What term is used for structures closer to the midline than another structure on the same side of the body?

Positions relative to the body's midline are described with directional terms. The midline is the imaginary vertical line that divides the body into left and right halves. When one structure lies closer to that midline than another structure on the same side, it is described as medial to the other structure. Medial means toward the midline; lateral means away from the midline. Proximal and distal describe closeness to the trunk or the limb’s point of attachment, not toward or away from the midline. So the term for being closer to the midline is medial.
