The term superficial refers to a structure that is b) toward or at the body surface.
In anatomy, the concept of superficiality refers to the position of a structure in relation to the surface of the body. When something is described as superficial, it means that it is closer to the outer surface, as opposed to being deeper within the body. This is a key term used to help describe locations of various structures in medical and anatomical contexts, making it easier for professionals to communicate about where things are located relative to one another.
