Axial skeleton of Humans

Axial Skeleton of the humans comprises of the Skull, the vertebrae and the sternum.
Skull :  It is made up of cranial and facial bones. The cranium consists of 8 bones ( 4 unpaireed and 2 paired which protects the Brain ). Parietal and temporal are paired bones while frontal, occipital, sphenoid and ethmoid are unpaired bones. Besides that there are 14 facial bones of which 6 are paired and unpaired. The paired facial bones are maxilla, zygomatic, lacrimal, palatine and inferior concha. The unpaired facial bones are mandible and vomer.
Vertebral column : Vertebral column extends from the skull to the pelvis to form backbone, which protects the spinal cord. Normally the vertebral column has 4 curvatures, which provide more strength than does the straight column. The vertebral column consists of 33 vertebrae. The vertebrae are named due to their location in the body, viz, cervical, thoracic, lumbar and pelvic.
Rib cage : It is composed of 12 pairs of ribs. that articulate with the thoracic vertebrae. Ten of them connect anteriorly with sternum, either directly or through the costal arch. The lower two pairs of ribs are called "floating ribs" because the do not attach to the sternum. The rib cage provides support to the semi-vaccum chamber called the "chest cavity".
