Which term refers to the direction toward the midline (toward the center of the body)?

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

Answer: (A)

Medial refers to direction toward the midline, the imaginary vertical line that runs down the center of the body and separates left from right. When something moves toward that line or is closer to it, it is described as medial. For example, the nose sits closer to the midline than the cheeks, so the nose is medial to the cheeks. In contrast, lateral describes something away from the midline toward the body's sides. Anterior means toward the front and posterior toward the back. Understanding medial helps you describe where structures are in relation to the center of the body, which is essential for talking about anatomy and movement.
