What does the term "dorsal" refer to in anatomical terms?

The term "dorsal" in anatomical terminology refers specifically to the top aspect or surface of a structure. In the context of the foot, the dorsal surface is the top side, where the toes are located. This term is commonly used in anatomy to describe the position of various body parts in relation to each other. For instance, when talking about the hand, the dorsal side would be the back of the hand.

In comparison to the other options, the bottom of the foot is referred to as the "plantar" surface, the inner side of the foot is termed the "medial" side, and the outer side is called the "lateral" side. Each of these terms describes specific orientations within anatomical terminology, but "dorsal" unmistakably indicates the top side, making it the correct choice in this case.
