The Axial Skeleton


The bones of the human body can be divided into two broad groups, the axial skeleton and the appendicular skeleton. The axial skeleton comprises the bones found along the central axis traveling down the center of the body. The appendicular skeleton comprises the bones appended to the central axis.

The axial skeleton consists of the bones of the skull, the bones of the inner ear (known as ossicles), the hyoid bone in the throat, and the bones of the veterbral column, including the sacrum and coccyx bones from center of the pelvic girdle.
