ANATOMY

Detailed explanation-1: -As with the other markings, their size and shape reflect the size of the vessels and nerves that penetrate the bone at these points. Figure 7.2. 1 – Bone Features: The surface features of bones depend on their function, location, attachment of ligaments and tendons, or the penetration of blood vessels and nerves.

Detailed explanation-2: -There are three general classes of bone markings: (1) articulations, (2) projections, and (3) holes. As the name implies, an articulation is where two bone surfaces come together (articulus = “joint”).

Detailed explanation-3: -Bone markings are very important since they allow for identification of bones and bony pieces, enable joints to form, enable bones to slide past each other, enable bones to lock in place, and provide places for muscle and connective tissues to attach and provide structural support.

Detailed explanation-4: -Bone markings are projections and depressions found on bones, which help us to identify the location of other body structures, such as muscles. Their importance comes when we try to describe the shape of the bone or to understand how the muscles, ligaments and other structures affect this bone and vice versa.
