Surface Anatomy

The study of form and markings of the body's surface, especially as they relate to internal structures.

In other words, even though your body is mostly covered with skin, you can still locate areas of internal anatomy by noticing creases, bulges and other characteristics in the skin.

You can picture exactly where a certain bone or muscle lines up, and follow it as the body moves. Where the bone connects to the skin you often find creases. Where the skin bulges you often have muscle. When the skin looks as if a cord is lying underneath, you're looking at a tendon. Where you find bumps as in the face, you're observing bone or cartilage protruding. In a way, by learning surface anatomy, you can virtually look through someone's skin and accurately imagine what's happening underneath.

In addition surface anatomy includes those structures that are outwardly exposed or openings to the outside of the body, including the eyes, ears, nose, mouth, nipples, belly button or umbillicus, anus, and external genitals or external sexual organs.
