Which term describes something that is located further beneath the surface of the body?

The term that describes something located further beneath the surface of the body is "deep." In anatomical terminology, "deep" refers to structures that are situated away from the surface of the body, indicating a position that is more internal compared to other structures. For example, muscles are often considered deep when compared to skin and fat tissues, which are more superficial or closer to the surface.

In contrast, "superficial" specifically denotes structures that are closer to the skin or surface, while "distal" and "proximal" relate to the distance from the point of attachment or trunk of the body, typically used in reference to limbs. Understanding these terms is critical in anatomy, as it helps in accurately describing the locations of various structures in relation to each other.
