Final answer:
Proximal describes a position in a limb that is nearer to the point of attachment or the trunk of the body. It is intermediate between more medial and more lateral structures.
Step-by-step explanation:
Proximal describes a position in a limb that is nearer to the point of attachment or the trunk of the body. For example, the brachium is proximal to the antebrachium. In this case, proximal is intermediate between the more medial (closer to the middle) and more lateral (closer to the side) structures.
