What directional term denotes a structure that is toward the head end or upper part of the body?

The term that denotes a structure toward the head end or upper part of the body is superior, also referred to as cranial in anatomical terminology. This term is commonly used to describe the relative position of body parts. For example, the head is superior to the neck, indicating that it is located above the neck.

In contrast, inferior refers to structures that are positioned toward the lower part of the body. Lateral describes a position farther away from the midline of the body, indicating a more outward location compared to other parts. Proximal is used to describe a position closer to the point of attachment of a limb to the body or closer to the trunk in general. By understanding these directional terms, one can accurately describe the location of various structures in relation to one another in the body.
