Document Summary

There are 206 bones in the body. The axial skeleton consists of the skull, vertebral column, and thoracic cage. There are 126 appendicular bones (64 upper limb, 62 lower limb). There are 80 axial bones skull (29), thorax (25), vertebral column (26). The skull actually has 22 bones because 6 are bones of the middle ear (3 pairs stapes, incus, malleus), and there s also a hyoid bone. Of the 22 bones, 8 are cranial bones (neurocranium) and 14 are facial bones (viscerocranium). The cranial bones are parietal (2), temporal (2), frontal (1), occipital (1), sphenoid (1), ethmoid (1). These tend to be flat plates of bone, with some bony landmarks. They are protective armour for the brain and are connected to each other by sutures. The facial bones are maxillae (2), zygomatic (2), lacrimal (2), inferior nasal concha (2), nasal (2), palatine (2), vomer (1), mandible (1). These tend to define sensory organs (eyes, nose, ears).
