Final answer:
Anterior (ventral) refers to the front of the body, while posterior (dorsal) refers to the back. Superior (cranial) describes a position above another body part.
Step-by-step explanation:
Anterior (or ventral) describes the front or direction toward the front of the body. For example, the toes are anterior to the foot. On the other hand, posterior (or dorsal) describes the back or direction toward the back of the body, like the popliteus muscle being posterior to the patella.
Superior (or cranial) describes a position above or higher than another part of the body. The orbits of the eyes are superior.
