SKELETAL SYSTEM, BONES OF AXIAL SKELETON, STUDY TOTAL 206 BONES OF THE HUMAN BODY, मानव कंकाल तंत्र

AXIAL SKELETON
Facial bone of Skull, 
Cranial bone of Skull, 
Vertebrae (vertebral column),
Ribs (24) and Sternum (1) (Rib cage),
Auditory ossicles,
Hyoid Bone,

SKELETAL SYSTEM
The skeletal system includes all of the bones and joints in the body. 
Each bone is a complex living organ that is made up of many cells, protein fibers, and minerals. 
The skeleton acts as a scaffold by providing support and protection for the soft tissues that make up the rest of the body

SKELETAL SYSTEM
SKELETAL SYSTEM divided into two divisions (206 bones)
1. Axial skeleton (80 bones)
Skull, 
Spinal column
Rib cage
2. Appendicular skeleton (126) 
Limbs and girdle

AXIAL SKELETON
The axial skeleton consists of the bones of the head and trunk of a vertebrate
Facial bone of Skull 
Cranial bone of Skull 
Vertebrae (vertebral column)
Ribs (24) and Sternum (1) (Rib cage)
Auditory ossicles
Hyoid Bone 

Skull (cephalic region) = 22 bones
SKULL TOTAL BONES 22
Cranial = 8 Facial = 14 
The skull is a bony structure that supports the face and forms a protective cavity for the brain. 
It is comprised of many bones, which are formed by intramembranous ossification, and joined by sutures (fibrous joints).

Skull (cephalic region) = 22 bones
Cranial = TOTAL 8
Frontal (1)
Occipital (1)
Ethmoid (1)
Sphenoid (1)
Parietal (2)
Temporal (2)

Skull (cephalic region) = 22 bones
Facial = TOTAL 14
Vomer (1)
Mandible (1)
Maxillae (2)
Zygomatic (2)
Nasal (2)
Nasal Concha(2)
Lacrimal (2)
Palatine (2)

Vertebral column = 26 bones
Also known as the spinal column, Central axis of the skeleton in all vertebrates. 
The vertebral column provides attachments to muscles, supports the trunk, protects the spinal cord and nerve roots & serves as a site for haemopoiesis (blood cell production)
Cervical (7)
Thoracic (12)
Lumbar (5)
Sacrum (1)
Coccyx (1)

Ribs and Sternum= 25 bones
The rib cage is the arrangement of ribs attached to the vertebral column and sternum in the thorax of most vertebrates
It encloses and protects the vital organs such as the heart, lungs and great vessels.
12 pairs of ribs = 24 ribs
1 sternum

The auditory ossicles are the three smallest bones in the human body, the malleus, the incus and the stapes
Total six Auditory ossicles (6) of both ear
–Malleus (2)
–Incus (2)
–Stapes (2)

HYOID BONE (1)
Only 1 single 
The hyoid bone (lingual bone or tongue-bone) is a horseshoe-shaped bone situated in the anterior midline of the neck between the chin and the thyroid cartilage. 
At rest, it lies at the level of the base of the mandible in the front and the third cervical vertebra (C3) behind.
