Bone markings, processes, and cavities



Most bones have some combination of bumps, ridges, projections, depressions, cavities, and holes in them that help them carry out their functions. These are where other structures like muscles, blood vessels and nerves, or other bones are attached to or articulate with or travel through the bone. Collectively, these kinds of features are called markings.

Although they are not always used consistently, there are general categories of these bone markings that you need to know before learning specific structural features on specific bones. Table 6.1 lists the types of structural features you need to know.
