Which term describes a direction toward the head end of the body?

The term that describes a direction toward the head end of the body is "superior." In anatomical terminology, superior refers to a position that is higher or closer to the head when compared to another part of the body. For example, the head is superior to the neck, meaning it is located above the neck in the body's anatomical hierarchy.

In contrast, "inferior" refers to a position lower or closer to the feet, such as the stomach being inferior to the chest. "Lateral" indicates a position away from the midline of the body, like the arms being lateral to the torso. "Medial," on the other hand, describes a position closer to the midline, such as the nose being medial to the cheeks. Thus, superior is the precise term to convey upward direction in relation to the anatomical structure.
