The skeleton consists of 206 bones and provides the framework of support for the attachment of ligaments and tendons. It is a store of calcium and provides cavities within various bones to produce blood cells.
Bone is made and broken constantly.
The first set of bones to be considered are the skeletal bones, overall. Figure 1 illustrates the skeleton with the key so you may learn the bones in their proper orientation. Figure 7 illustrates the mandible. Figure 8 illustrates the first two vertebra in the neck, i.e., the first two cervical vertebra. Note how the mechanics of rocking and rolling and pivoting the head have been built into these two vertebra.
