Final answer:
In anatomical terms, 'superficial' describes structures near the body's surface, like the skin; 'deep' refers to structures further inside, like the brain. The brain is an example of a deep structure since it is located inside the skull, away from the body's surface.
Step-by-step explanation:
The term superficial is used in anatomy to describe a structure that is closer to the surface of the body. For example, the skin is considered superficial to the bones because it is on the outside, covering the bones. On the other hand, structures that are located deeper within the body are described as deep. The brain is an example of a deep structure since it is located inside the skull, away from the body's surface. On the other hand, deep describes a position farther from the surface of the body. The brain is deep to the skull.
