The prefix epi- denotes which directional relation to a surface?

Explanation:
The prefix epi- means located on or just above a surface. In anatomical terms, it describes something that is on the exterior surface or overlying the underlying structure. For example, the epidermis is the outermost surface layer of the skin, and the epigastric region is the area above the stomach. It’s not about being below or inside; those positions would use different prefixes like sub- or hypo- (below) or endo- or intra- (inside). So epi- specifically conveys "on" or "above" a surface.
