Concept 6: Superfi cial and Deep
The terms superficial and l deep describe locations in relation to the surface of
the body. If a body part is superficial, it is closer to the surface of the body. If a
body part is deep, it is farther from the surface of the body. For example, the
muscles of the face are superficial to the brain. The brain is deep to the muscles
of the face. The skull is deep to the muscles of the face, but superficial to the
brain (Figure 9.15).
