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.
- Fingernails grow four times faster than toenails.

due to ordinary wear and tear.
- The skin is the largest organ in the body.
- There are 650 sweat glands in one square
inch of skin.
