No bones in the body have the simplified shape of dog treat bones especially the bones of the head and neck many of which have very complex shapes. The configuration of a bone depends on its function. Bones surrounding important organs like the brain, eyes and hearing/equilibrium apparatus are shaped to protect, while bones that are not necessary for protection are often paper thin. Bones that encase the brain also have to allow for passage of nerves and blood vessels into and out of the cranium. Areas where muscles attach are thicker to be able to anchor the muscle without breaking. As each bone is discussed in the course, we will discuss the various depressions, openings and protrusions found on that particular bone.
