Title: Human nose
Content:  The skin of the nose varies in thickness along its length. From the glabella to the bridge (the nasofrontal angle) the skin is thick, fairly flexible, and mobile. It tapers to the bridge where it is thinnest and least flexible as it is closest to the underlying bone. From the bridge until the tip of the nose the skin is thin. The tip is covered in skin that is as thick as the top section, and has many large sebaceous glands. The thickness of the skin varies but is still separated from the underlying bones and cartilage by four layers – a superficial fatty layer; a fibromuscular layer continued from the SMAS; a deep fatty layer, and the periosteum. Other areas of soft tissue are found where there is no support from cartilage; these include an area around the sides of the septum – the paraseptal area –, an area around the lateral cartilages, an area at the top of the nostril, and an area in the alae.
Title: Human nose
Content:  The nasal cavity is the large internal space of the nose, and is in two parts – the nasal vestibule and the nasal cavity proper. The nasal vestibule is the frontmost part of the nasal cavity, enclosed by cartilages. The vestibule is lined with skin, hair follicles, and a large number of sebaceous glands. A mucous ridge known as the limen nasi separates the vestibule from the rest of the nasal cavity and marks the change from the skin of the vestibule to the respiratory epithelium of the rest of the nasal cavity. This area is also known as a mucocutaneous junction and has a dense microvasculature. The nasal 
Title: Rhinarium
Content:  The rhinarium (New Latin, "belonging to the nose"; plural: rhinaria) is the furless skin surface surrounding the external openings of the nostrils in many mammals. Commonly it is referred to as the tip of the snout, and breeders of cats and dogs sometimes use the term nose leather. Informally, it may be called a "truffle", "wet snout" or "wet nose," because its surface is moist in some species: for example, healthy dogs and cats. In many species, the rhinarium has a mid-line groove (cleft) – the philtrum – and a wrinkled (crenellated) surface. The rhinarium is a separate sense organ: it is a touch-based chemosensory organ that connects with a well-developed vomeronasal organ (VNO). The rhinarium is used to touch a scent-marked object containing pheromones (usually large, non-volatile molecules), and transfer these pheromone molecules down the 
Title: Mucocutaneous junction
Content:  A mucocutaneous junction, or mucocutaneous boundary, is a region of the body in which mucosa transitions to skin. Mucocutaneous zones occur in animals, at the body orifices. In humans, mucocutaneous junctions are found at the lips, nostrils, conjunctivae, urethra, vagina (in females), foreskin (in males), and anus. In the nostrils the mucocutaneous junction has a dense microvascular network, and shows a marked similarity to that found in the mouth, between the oral mucosa and the lips. At a mucocutaneous junction, epithelium transitions to epidermis, lamina propria transitions to dermis, and smooth muscle transitions to skeletal muscle. A mucocutaneous junction is often the site of an arterial anastomosis, a watershed area of venous and lymphatic drainage, and sensory (but not motor) nerve overlap. Winkelmann (1959) documented that the mucocutaneous boundary is a "specific erogenous zone with rete ridges where the nerve endings rise closer to the surface".
Title: Nose
Content:  A nose is a protuberance in vertebrates that houses the nostrils, or nares, which receive and expel air for respiration alongside the mouth. Behind the nose are the olfactory mucosa and the sinuses. Behind the nasal cavity, air next passes through the pharynx, shared with the digestive system, and then into the rest of the respiratory system. In humans, the nose is located centrally on the face and serves as an alternative respiratory passage especially during suckling for infants. The protruding nose that completely separate from the mouth part is a characteristic found only in therian mammals. It has been theorized that this unique mammalian nose evolved from the anterior part of the upper jaw of the reptilian-like ancestors (synapsids).
Title: Rhinoplasty
Content: Nasal skin – Like the underlying bone-and-cartilage (osseo-cartilaginous) support framework of the nose, the external skin is divided into vertical thirds (anatomic sections); from the glabella (the space between the eyebrows), to the bridge, to the tip, for corrective plastic surgery, the nasal skin is anatomically considered, as the: 1) Upper third section – the skin of the upper nose is thin, subcutaneous fat layer is thicker and relatively distensible (flexible and mobile), but then tapers, adhering tightly to the osseo-cartilaginous framework, and becomes the thinner skin of the dorsal section, the bridge of the nose. ; 2) Middle third section – the skin overlying the bridge of the nose (mid-dorsal section) is the thinnest, least distensible, nasal skin, because it most adheres to the support framework. ; 3) Lower third section – the skin of the lower 
Title: Rhinoplasty
Content:  alar cartilage, which supports the nasal tip, and is responsible for the light reflex of the tip. ; 2) the nasal lining – A thin layer of vascular mucosa that adheres tightly to the deep surface of the bones and the cartilages of the nose. Said dense adherence to the nasal interior limits the mobility of the mucosa, consequently, only the smallest of mucosal defects (< 5 mm) can be sutured primarily. ; 3) the nasal skin – A tight envelope that proceeds inferiorly from the glabella (the smooth prominence between the eyebrows), which then becomes thinner and progressively inelastic (less distensible). The skin of the mid-third of the nose covers the cartilaginous 
Title: Nasal mucosa
Content:  The nasal mucosa lines the nasal cavity. It is part of the respiratory mucosa, the mucous membrane lining the respiratory tract. The nasal mucosa is intimately adherent to the periosteum or perichondrium of the nasal conchae. It is continuous with the skin through the nostrils, and with the mucous membrane of the nasal part of the pharynx through the choanae. From the nasal cavity its continuity with the conjunctiva may be traced, through the nasolacrimal and lacrimal ducts; and with the frontal, ethmoidal, sphenoidal, and maxillary sinuses, through the several openings in the nasal meatuses. The mucous membrane is thickest, and most vascular, over the nasal conchae. It is also thick over 
Title: Cartilage piercing
Content: Nostril: A piercing passing through the nostril on either side and ending in the inside of the nose. ; High Nostril: A piercing placed further towards the top of the nose, much closer to the bone than a standard nostril piercing. ; Nose Tip: A piercing that begins within either nostril and exits at the tip of the nose. ; Nasallang: A set of three piercings connected by one piece of jewelry, usually a barbell. Both nostrils are pierced, as well as the septum. Depending on anatomy, the piercer, and the preference of the client, the septum piercing may or may not go through cartilage. ; Septum: The piece of tissue in the middle of the nose separating the two nostrils. A septum piercing is often incorrectly regarded as a cartilage piercing. While some people do have septum piercings which pass through cartilage, most septum piercings pass through the small bit of tissue directly beneath the cartilage and above the skin. 
Title: Human nose
Content:  rhinion to the apex, or tip, the framework is of cartilage. The major alar cartilages are thin, U-shaped plates of cartilage on each side of the nose that form the lateral and medial walls of the vestibule, known as the medial and lateral crura. The medial crura are attached to the septal cartilage, forming fleshy parts at the front of the nostrils on each side of the septum, called the medial crural footpods. The medial crura meet at the midline below the end of the septum to form the columella and lobule. The lobule contains the tip of the nose and its base contains the
