MEDICAL PHYSIOLOGY

Detailed explanation-1: -Deep refers to structures closer to the interior center of the body. For example, bones in an appendage are located deeper than the muscles. Superficial is used to describe structures that are closer to the exterior surface of the body. For example, the outer layers of skin are superficial to deeper layers of skin.

Detailed explanation-2: -Inferior. Below another structure. e.g. The feet are at the inferior part of the body.

Detailed explanation-3: -The term superficial is a directional term used to describe the position of one structure relative to the surface of the body or to another underlying structure. The opposite of superficial is deep, which indicates that a structure is further away from the external surface of the body.

Detailed explanation-4: -Lateral. Away from the midline of the body (the arms are lateral to the heart) Deep. On the inside; underneath another structure (muscles are deep to the skin)
