Anatomical Association Between Articularis Genus and Vastus Medialis Oblique: A Cadaveric Investigation
Authors: Adds Philip , Javed Komal
Published: December 2023

Objectives The articularis genus (AG) muscle is thought to elevate the suprapatellar bursa during knee extension. Failure of this function may cause impingement of the bursa, and lead to anterior knee pain. The AG may work in synergy with the vastus medialis oblique (VMO) to fulfil this function. The AG and the VMO both attach to the vastus intermedius aponeurosis, and fibres of the VMO have been found to attach to the superficial layer of the AG. The VMO is also implicated in anterior knee pain, as VMO insufficiency can lead to patellar maltracking. The aim of the study was to investigate if an anatomical association could be shown between the AG and the VMO. Methods Twenty-nine lower limbs were dissected to show the muscles of the anterior thigh. The maximum VMO pennation angle and the VMO insertion ratio on the medial border of the patella were measured. The AG area was determined by measuring the length and maximum width of each individual muscle slip. Results The mean area of the AG was 2554.67 mm2. The mean VMO angle was 56.6°, whilst the mean insertion ratio was 48.93%. The association between area and each of the covariates was not statistically significant (VMO angle: P=0.921; insertion ratio: P=0.822). The mean area for the left leg was greater than that for the right (2876.12 versus 2233.22; P=0.049). Conclusion The articularis genus does not appear to have an anatomical association with the vastus medialis oblique. The dimensions of the superficial layer of the AG were not influenced by sex or age. However, the AG area was greater on the left limb than the right.
Pulmonary Fissures – How do they form?
Authors: May Christian Albrecht
Published: December 2023

For pulmonary surgery, the variation of pulmonary fissures matters but little is known about their development. Early fixation of the visceral pleura seems to be mediated by myofibroblasts and extracellular components like fibronectin. So far, no concepts explain sufficiently the origin of the shape and orientation of these fissures.
MACROMICROSCOPIC CHARACTERISTICS OF INDIVIDUAL AND AGED VARIABILITY OF THE GLANDS OF THE VAGINAL VESTIBULE
Authors: SV Shadlinskaya
Published: December 2023

The aim of the study was to obtain data on the aged and individual characteristics of the glands of the vaginal vestibule in women under conditions of a relative norm. Material and research methods. By the macromicroscopic way, the small glands of the vaginal vestibule wall were investigated in 163 women of different ages who died or died from accidental causes, without pathology of the urogenital system. The area of ​​the vestibule was dissected from the corpse by the preparation method. Next, the glands on the total preparation were stained in a 0.5% solution of acetic acid with a 0.05% solution of methylene blue in tap water [7] and fixed in a saturated solution of picric acid (molybdenum acid) ammonium. Using a MBS-9 binocular stereomicroscope (magnification. 8-64x), the total number of small glands, the length and width of their initial parts, the diameter of their common excretory duct (using an ocular ruler), and the percentage of glands with different numbers of initial parts were determined. The results of the study. We found that in newborns the glandular apparatus of the vaginal vestibule is structurally formed. The maximum number and size of small glands of the vaginal vestibule are determined in the 1st period of adulthood. At the macromicroscopic level, involution of the glands is manifested by a decrease in their total number and size. The expansion of the excretory ducts of the glands occurs sequentially throughout postnatal ontogenesis. In long-livers in comparison with senile age, there is almost no further decrease in the number and size of glands of the vaginal vestibule.
Palmaris Longus Inversus Muscle Present Bilaterally in an 82 Year-old White Female Cadaver and Unilaterally in a 68 Year-old White Female Cadaver
Authors: Granite Guinevere , Wind Gary , Leighton Ximena
Published: December 2023

The palmaris longus muscle is one of the most variable muscles in the human body. Palmaris longus muscle anatomical variations include reversed (palmaris longus inversus muscle), duplicated, triplicated, bifid, hypertrophied, accessory (additional) slips, and/or complete absence. During anatomical dissection of fifty cadavers in the 2019 undergraduate first-year anatomy course at the Uniformed Services University of the Health Sciences, we found a palmaris longus inversus muscle bilaterally on an 82 year-old White female cadaver and a unilateral palmaris longus inversus muscle on the right forearm of a 68 year-old White female cadaver. Due to the prevalence of anatomical variations in the palmaris longus muscle, adequate knowledge of such prevalence and clinical significance is needed in multiple medical specialties for its reconstructive use, and the possibility and treatment of clinical syndromes. An accessory (additional) palmaris longus muscle, hypertrophied palmaris longus muscle, hypertrophied palmaris longus inversus muscle, or just the presence of a palmaris longus inversus muscle, can all cause compression to adjacent neurovascular structures, such as the median nerve, ulnar nerve, ulnar artery, and/or the anterior interosseous artery, in the distal forearm and wrist. Palmaris longus tendons are used as grafts in various surgeries, such as extensor tendon repair in rheumatoid arthritis patients, injuries of flexor tendons and repair, lip augmentation, reconstructive hand surgery, frontalis suspension sling in ptosis correction, plastic surgery, and pulley reconstructions. Surgeons, physicians, radiologists, and physiotherapists must be knowledgeable of the many PLM anatomical variations and their possible contributions to pathological processes.
Polythelia associated with hypogonadotropic hypogonadism in young male: A case report
Authors: Hegazy Abdelmonem Awad Mustafa , Hadhoud Khaled , Hegazy Mustafa Abdelmonem Hegazy
Published: December 2023

Polythelia is a congenital anomaly in which there is a third or more nipples. Although it is a relatively rare condition, it is frequently associated with other congenital malformations including the cardiovascular, urogenital, and skeletal systems. It may occur sporadically or with a familial tendency with some genetic factors. We report an association of polythelia with congenital hypogonadotropic hypogonadism (CHH) in a young male. The patient was complaining of delayed puberty. He was short in stature and had hypogonadism. On physical examination, a third nipple was found below the normal left nipple along the left mammary line. The case was carefully evaluated to exclude other disorders. It has been suggested that every newborn can be checked for the presence of accessory nipples which could indicate another internal problem in its body. We report the association of accessory nipple and right-sided hydronephrosis in a female term newborn.
The musculocutaneous nerve completely fused with lateral root , partially with median nerve while not perforating coracobrachialis muscle: Its embryological basis and literature review
Authors: KOPUZ Cem , İçten Nihal
Published: December 2023

An rare anomaly of the musculocutaneous nerve was detected during routine dissection of the left upper limb of a 42-year-old Turkish male cadaver. MCN extend in a common sheath together with the lateral cord (LC) and lateral root of MN without leaving LC. The lateral and medial roots combined ventral to the axillary artery forming a common trunk of the MCN and MN. The MCN left the MN 0,5 cm distal to the junction of the lateral and medial roots of MN. It traveled between the biceps brachii and coracobrachial muscles without piercing the coracobrachial muscle and crossed over the axillary artery. Later, the MCN passed between the biceps and brahial muscles and continued as the lateral cutaneous nerve. No a prominent branch to the coracobrachialis muscle originating from MCN. It was observed that very thin branches extend from the lateral cord and MCN to the coracobrachialis muscle. A connection extending from the proximal of the LC to the point where the ulnar nerve originated in the distal part of the MC was also detected. A good knowledge of the anatomical variations for upper extremity surgical interventions and treatments helps surgeons to avoid potential errors during surgery. Considering that our case does not fit the cases in the classifications found in the literature, or is compatible with more than one proposed variation, we rarely find this variation, as we cannot really find anything similar.
A look at early human embryonic development and the importance of darkness for embryogenesis
Authors: Hegazy Abdelmonem Awad Mustafa
Published: December 2023

Human development is a highly complex process where a single cell called zygote forms a multicellular body made up of trillions of cells. Human pregnancy takes about 10 lunar months or 40 weeks. Prenatal life is divided into three stages namely germinal, embryonic and fetal stages. All stages are critical, but the most important is the embryonic stage through which embryogenesis occurs. It normally occurs in the upper segment of the uterus into its endometrium, called decidua after occurrence of conception. Many factors can affect embryogenesis including the mother's use of medications and even the mother's psychological state. Of these factors, light may be. The embryo is surrounded by three regions of darkness These areas from the inside out are the amniotic cavity, the uterine cavity, and the abdominal cavity. Light could affect embryonic development either by direct toxic effect on the embryo, or indirectly by photo-oxidation of components in media. Therefore, it is necessary to study them in future studies to investigate the potentially harmful effect of light exposure on embryonic development. This may be useful to avoid potential obstacles to the IVF process as embryos can be exposed to light sources of varying intensity.
A Cadaveric Study on Morphology and Morphometry of Pectoralis Major Muscle
Authors: Waghray Nitya , Pusala Bheemesh , Kishve Prajakta
Published: December 2023

Background: The Pectoralis Major (PM) muscle is considered one of the key anatomical structures in plastic and reconstructive surgery. The objective is to study the morphology of PM along with a thorough assessment of its dimensions and to note any other anatomic variations. Subjects and Methods: The study was carried out on 30 upper limb specimens (Right 15 & Left 15) of both sexes available in the department of anatomy. The morphometric analysis at the origin and insertion was done and the muscle was thoroughly observed for any other anatomical variations. Results: We observed that the entire length of the clavicle gave origin to the clavicular head in 6.6% of the specimens and the deltopectoral groove was absent in 6.6% of the cases. 66.6% of the specimens showed the continuation of the pectoralis muscle at its insertion along with the brachial fascia. In 3.3% of the cases, the three heads of the pectoralis major were not distinguishable. The mean height at the midclavicular line was found to be 13.8 cm and at the midaxillary line, it was found to be 6.6 cm. The average width was found to be 18.7cm at the origin. The average length at the insertion was found to be 4.8 cm and the height was found to be 0.89cm. Conclusion: The knowledge regarding pectoralis major is imperative for surgeons in performing surgeries in the pectoral region, especially the surgeries involving the mammary gland.
Pyramidal Lobe of the Human Thyroid Gland: A Case Report
Authors: Ochieng John Juma
Published: December 2023

Background The thyroid gland is amongst the most anatomically variable structures in the human body, with incidence of the pyramidal lobe ranging from 57-65%. While these anatomical variations remain overlooked or misinterpreted by students during routine laboratory dissection, they are of clinical relevance in terms of functional disorders and illnesses associated with thyroid gland. Multiple patterns of the pyramidal lobe have been identified during routine dissections and reported in the literature. The knowledge of these pattern differences is vital for surgical practice and patient management. This is a report on a 42-year-old African male cadaver with a pyramidal lobe noticed during routine dissection in Human Anatomy Laboratory, Department of Human Anatomy of Uzima University. Method: Dissimilarity was encountered during routine cadaveric dissections, overlying neck muscles were exposed, and the tissue was examined. Results: The macroscopic assessment revealed a capsulated glandular tissue with three lobes. Pyramidal lobe was located deep to the strap muscles of the neck at the midline below the Adam’s apple. Conclusion: Pyramidal lobe is considered a normal component of the thyroid gland with variable morphology and position. Its removal during surgery of the thyroid to treat non-malignant disease cases has proven to significantly reduce chances of cancer recurrence.
Flexor Carpi Radialis Brevis: A Case Report
Authors: Calhoun Wesley , Ford Seth , Caulkins R Mark , McKeon Kathleen E , Washmuth Nicholas
Published: December 2023

The flexor carpi radialis brevis is a rare anomalous muscle, with incidence ranging from 1.6-7.5%. While this anatomical variation is typically benign, it is of clinical importance as it can contribute to neurovascular and musculoskeletal dysfunction. Surgeons should be made aware of this variation during distal radius volar plating procedures and carpal tunnel releases. The flexor carpi radialis brevis muscle may also cause confusion when interpreting imaging results. We report here a rare case of bilateral flexor carpi radialis brevis muscles that travel through the carpal tunnel found during cadaveric dissection in a graduate course for physical therapy students. To our knowledge, this is the second published example of a flexor carpi radialis brevis muscle traveling through the carpal tunnel.
A Case Report on Carpal Synostosis in an Eight-Year-Old Male
Authors: Arkoh Samuel , Denteh Stephen
Published: December 2023

Introduction: Carpal synostosis is a medical condition in which adjacent carpal bones become fused with or without other associated limb deformities. According to literature, carpal synostosis has a relatively low incidence rate of 0.1%. Case report: We report a case of an isolated complete lunotriquetral synostosis of an eight year-old male revealed incidentally upon x-ray examination to rule out fracture of the distal forearm post trauma. Discussion: There is but little literature of an isolated carpal coalition of a pediatric at the time of this report. Also, there is no standardized classification system for carpal coalition due to insufficient imaging data by virtue of rarity of the condition and incomprehensive description of the morphology of coalitions, among others. Though patient’s lunotriquetral synostosis was not seen to impair wrist function, the radiologist report revealed negative ulnar variance, thus the need for further investigation into its possible association. Conclusion: This report adds up to existing literature to contribute a better classification system of carpal synostosis. Association between carpal synostosis and ulnar variance should be further explored.

Published: December 2023

Anatomical variations of peripheral nerves are commonly reported in the literature. While typically benign, they are of clinical importance as they can contribute to atypical clinical presentations, cause difficulty with imaging and nerve conduction studies, and lead to surgical challenges for surgeons. We report here a communicating branch between the musculocutaneous nerve and median nerve found during cadaveric dissection in a Doctor of Nursing Practice course in the Department of Nurse Anesthesia at Samford University. Although the case described here is among the most common anatomical variations of the peripheral nerves, there are classification systems for this variation that need to be recognized and applied by anatomists, clinicians, and surgeons.
Bilateral Long Head of the Triceps Brachii Muscle Innervation via Axillary Nerve: A Case Report
Authors: Scogin William M. , Vinson Alexandra R , Pfister Cristina B
Published: December 2023

The radial nerve has traditionally been considered the innervation of the long head of the triceps brachii (LHT). However, cadaveric studies have discovered LHT innervation via the axillary nerve in roughly 6-15 % of shoulders. A cadaver with exclusive axillary nerve innervation to the LHT bilaterally was discovered during cadaveric dissection in a graduate course at Samford University. This anatomical variation may have clinical implications for surgeries, shoulder dislocations, and quadrilateral space syndrome. Axillary nerve injuries may additionally present with shoulder extension and elbow extension weakness if this variation is present.

Published: December 2023

Head and neck anatomic variations are common and generally go undetected, but may be clinically significant or have important surgical consequences. Knowledge of various abnormalities is important for clinical decision making and the avoidance of iatrogenic complications. Anomalies of the aortic arch and its various branches are relatively common. However, rare variations with profound clinical sequelae can occur. During recent cadaveric dissection, we identified an 83-year-old and a 93-year-old White male donor who both had a right retroesophageal subclavian artery with an associated non-recurrent right laryngeal nerve. Lack of knowledge of this anatomic variation can directly result in severe consequences for patients and lead to major morbidity. Understanding this variation and recognizing it will be important for anatomists, radiologists and surgeons.
Potential Rheumatological Heart Disease Causing Triple Valve Replacement: A Case Report
Authors: Karmilkar Kunal , Collier Larissa
Published: December 2023

INTRODUCTION: Mechanical valves were identified in the aortic, mitral, and tricuspid valves of an 88-year-old donor. The presence of these valves along with the donor's past medical history and body habitus indicate a triple valve replacement surgery was performed. CASE PRESENTATION: Here we describe our 88-year-old donor’s body habitus during routine anatomical dissection. DISCUSSION: Evidence of a rare triple valve surgery is discussed along with how this type of case report acts as a useful exercise contributing towards medical student education. CONCLUSION: A rare triple valve replacement appears to have been performed on our donor.
A conservation program for the yellow-breasted capuchin monkey, Cebus apella xanthosternos
Authors: Santos Ilmar B. , Lernould Jean-Marc
Published: December 2023

The yellow-breasted capuchin is one of the four currently recognized subspecies of the tufted, or brown, capuchin monkeys which occur in central, northeastern and southeastern Brazil. It is a phenotypically and genetically distinct animal (Seudnez et al.,1986; Matayoshi ef al.,1987) and, depending on a taxonomic revision of the genus, may well be considered a valid species. It quite evidently had a widespread distribution in the past, east and south of the Rio Sao Francisco, east as far as the coastal forests in the state of Bahia. Today it is limited mainly to the coastal region of southern Bahia in Brazil, although evidence is coming to light that some populations may remain further inland in regions devastated in the distant past and now comprising mainly dry desert thorn scrub (caatinga). Populations inland are extremiely rare, and have disappeared over enormous areas. They are evidently declining drastically throughout their rangc, not only because of forest destruction, which has accelerated dramatically over the last two decades, but also because of hunting (Mittermeier ef al., 1982, 1989; Coimbra-filho, 1986; Santos et al., 1987; Oliver and Santos, 1991).

Two new species of marmoset, genus Callithrix Erxleben, 1777 (Callitrichidae, Primates), from the Tapajós/Madeira interfluvium, south central Amazonia, Brazil
Authors: Van Roosmalen Marc G. M. , Van Roosmalen Tomas , Mittermeier Russell A. , Rylands Anthony B.
Published: December 2023

Two new species of marmoset, Callithrix manicorensis sp. n. and Callithrix acariensi sp. n., are described; the first from the interfluvium of the Rios Madeira, Aripuanã and Manicoré, and the second from the interfluvium of the Rios Acarí and Sucundurí, south of their confluence with the Rio Canumã, both in the state of Amazonas, south central Amazonia, Brazil. The new species are members of the Callithrix argentata group of marmosets, sensu Hershkovitz (1977). Callithrix manicorensis appears to be most closely related to C. nigriceps, C. marcai and C. aff. emiliae, its neighbors to the south, and Callithrix acariensis appears to be most closely related to Callithrix saterei, its neighbor to the north, and Callithrix melanura to the south, but they are easily distinguished from them. The most noticeable features of Callithrix manicorensis are the almost white or silvery upper parts including the arms, hands, chest, mande, nape and forehead, and the indistinct light gray (rather than black) cap on the head. The back is grayish and transversely white or silvery striped or mottled. The under parts are yellowish or orange. The legs and feet are orange. The tail is black. Those of Callithrix acariensis include the almost entirely snow white upper parts including the upper arms, chest, mande, nape and forehead, and the lack of a dark cap on the head. The back is grayish. The under parts are white. The legs and feet are bright orange. The tail is dark black with a bright orange dorsal patch at the proximal end. Most strikingly, this species shows a broad white hip and thigh stripe running from the mid dorsum (almost continuing across the back) to the knee. The phylogenetic status of the two new marmoset taxa is presented based on 902 base pairs (bp) of the mitochondrial control region and combined with previously determined sequences from related species. Additionally, 635 bp of intron 2 of the nuclear b2-microglobulin gene was sequenced for C. manicorensis and combined with sequences from related species. Callithrix manicorensis is shown to be a member of the C. argentata clade according to mitochondrial control region and b2-microglobulin intron 2 sequences. Callithrix acariensis is found to be most closely related to C. mauesi and C. humeralifera (the tufted-ear marmoset clade) based on mitochondrial control sequence. The phylogeography of the marmosets is discussed, as well as possible scenarios for historic patterns of dispersal and speciation. With the discovery of these two marmosets, the number of species of Callithrix increases to 21, of which 20 are endemic to Brazil (considering C. aff. emiliae from Rondônia a valid species as it is widely separated from C. emiliae). The total number of primate species for the country as a whole increases to 79, 41 of which are endemic.

Entre Enero y Mayo del 2000 se llevaron a cabo tres reconocimientos de la población del mono aullador negro existente en la selva del sitio arqueológico de Palenque, Chiapas, México. Detectamos la presencia de 99 individuas repartidos en 13 tropas, con la posible existencia de 3-5 tropas adicionales. La densidad ecologica estimada fue de 33 individuos/km2 . El tamafio media de las tropas fue 7.6 (rango 2-13). Todos los avistamientos de los manos aulladores fueron en selva alta perennifolia y en árboles >20m en altura. Las densidades reportadas para Palenque son más altas que aquellas reportadas para la misma especie en Belice y Guatemala y en Quintana Roo en México y otro contrast es que, en Palenque, la mayoría de las tropas (70%) eran multimacho. La protección de un perímetro amplio (c. 1700 ha) alrededor de la selva que cubre el sitio arqueológico por el gobierno Mexicano asegura la conservación de la selva y de la población del mono aullador negro existente en el sitio.

La fragmentación y aislamiento del hábitat natural de los primates silvestrespor la actividad humana tiene un impacto importante sobre el comportamiento alimenticio y los patrones de actividad general de morros aulladores. La variaciones en estos comportamientos pueden representar ajustes por parte de los aulladores a condiciones ambientales cambiantes. Sin embargo, lainformación disponibleenlaliteraturaacercadeestosefectosesescasa.Enestetrabajoreportamoslaspreferenciasalimenticias de tropas de morros aulladores (A. palliata) existiendo en un fragmento pequeno (3 ha), uno m.ediano (35 ha) y uno grande (250 ha) en la región de Los Tuxtlas, México. Los resultados mostraron una tendencia hacia una dieta más diversa del fragmento pequeno al grande. Una tendencia similar fue observada en cuanto al número de especies arbóreas utilizadas por los aulladores, el cual varió de 6 a 15 a 22. La dieta de la tropa en el fragmento pequeno estuvo dominada por el consumo de hojas (80% del tiempo alimenticio), mientras que en el fragmento mediano y grande el consumo de hojas contribuyó al 44% y 22% del tiempo alimenticio respectivamente. En estos últimos dos sitios los aulladores también consumieron proporciones importantes de frutos y flores. Observamos una tendencia, en la proporción de tiempo invertido por los aulladores en viajar de un lado a otro, a disminuir del fragmento grande al pequeno, sugiriendo limitaciones importantes en los desplazamientos de la tropa dentro de su área de suministro. Nuestro estudio sugiere el uso de una perspectiva a nivel del paisaje en el estudio y conservación de tropas de morros aulladores existiendo en hábitats fragmentados.

Population growth in the Belizean black howling monkey (Alouatta pigra)
Authors: Horwich Robert H. , Brockett Robin C. , James Roxie A. , Jones Clara B.
Published: December 2023

Population growth in black howling monkeys (Alouatta pigra) was studied in an area of 0.63 km2 from 1990 to 1999 at the Community Baboon Sanctuary, Bermudian Landing, Belize, Central America. Population density increased over time, and population growth was found to be density-dependent, with a higher rate of increase between 1991-1996 than between 1997-1999. The shape of the age distribution of the population was similar across years, although the proportion of adult males in the population decreased significantly with increased population density. Changes in membership over time for 18 monkey groups suggested that population growth may also result from an increase in the number of groups and length of tenure of groups. Groups with no or only one immature (infant, juvenile, or subadult) were confined to the period of population increase. Although more male infants were estimated to have survived to the juvenile age class, the result was statistically insignificant. Interbirth intervals were within the range for other species of Alouatta. Our results also indicate that increased population density and consequent increases in mean group size decrease the ability of single males to monopolize female groups due, in part, to decreased opportunities for single males to found new groups. A consequence of this condition would be increased male-male competition for mates.

Presence of the muriqui (Brachyteles hypoxanthus) in a rural property in the vicinity of the Augusto Ruschi Biological Reserve, Santa Teresa, Espírito Santo
Authors: Vieira Luciano A. , Mendes Sérgio L.
Published: December 2023

This note reports on three sightings, in 2005, of muriquis in a forest on private land to the north of the Augusto Ruschi Biological Reserve. The forest there is dense montane evergreen forest. The sightings were of four, three and four individuals respectively, one of them including a female with an infant. We emphasize the importance of maintaining forest patches on private land and their role in enhancing the survival of populations of threatened species in small protected areas such as the Augusto Ruschi Biological Reserve.
Survey and status of the muriquis (Brachyteles arachnoides) in the Serra dos Órgãos National Park, Rio de Janeiro
Authors: Garcia Vânia Luciane Alves
Published: December 2023

The Serra dos Órgãos National Park protects 11,800 ha of Atlantic forest in the state of Rio de Janeiro (22°30'S, 43°06'W; 300 to 2,263 m above sea level). Vegetation types include montane dense evergreeen forest up to altitudes of 1,800 m; cloud forest from 1,800 to 2,000 m; and high altitude grassland above 2,000 m. This paper reports on surveys carried out in 10 localities in the park specifically to obtain a minimum estimate of the population of northern muriquis (Brachyteles arachnoides). Muriquis were sighted 26 times at altitudes ranging from 800 to 1,500 m. It is possible that they belonged to four groups in which case the minimum number of individuals recorded would be 56. If in fact the sightings were of just two groups, the minimum number of individuals would be 32. Black-horned capuchin (Cebus nigritus) and brown howler monkeys (Alouatta guariba) were also recorded for the park. The buffy-tufted-ear marmoset (Callithrix aurita) was not seen.

We briefly describe in this paper the objectives, structure and organization of the International Committee for the Conservation and Management of the Atlantic Forest Atelids. This is an advisory group established to assist the Brazilian Institute for the Environment (Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis – IBAMA) in the definition of effective conservation measures for the two species of muriqui (Brachyteles hypoxanthus and B. arachnoides) along with the northern brown howling monkey (Alouatta guariba guariba), all of which are on the Brazilian Official List of Fauna Threatened of Extinction. We also describe the participation of IBAMA’s Center for the Protection of Brazilian Primates (Centro de Proteção de Primatas Brasileiros – CPB) and the Coordination for the Conservation of Threatened Fauna and Migratory Species (Coordenação de Conservação das Espécies da Fauna Ameaçada de Extinção e Migratória – COFAU). These are the sectors of IBAMA most involved with the planning and execution of conservation actions for threatened primates in Brazil.
