In anatomical position, directional terms describe the relative positions of body parts. Superior means above, inferior means below, proximal means closer to the origin or trunk, distal means farther away, anterior (ventral) means front - facing, posterior (dorsal) means back - facing, medial means closer to the midline, and lateral means farther from the midline.
