Which directional term means the middle?

• A. Medial
• B. Lateral
• C. Sagittal
• D. Posterior

Answer: (A)

In anatomy, directional terms describe where a body part is relative to the body's midline. Medial means toward that midline—the center line that divides the body into left and right halves. So structures closer to the midline are medial, while those farther away are lateral. For example, the nose is closer to the midline than the ears. Sagittal describes a plane or direction that runs front to back and divides left from right, not specifically the middle. Posterior means toward the back, with anterior toward the front. Therefore, the term for the middle is medial.
