What term describes toward the midline of the body?

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

Answer: (A)

Understanding body directions helps describe where things are in relation to each other. The midline is an imaginary line that runs down the center of the body, dividing it into left and right halves. A structure described as toward the midline is closer to that line, which is called medial. So, medial means closer to the center of the body, like the nose being medial to the cheeks or the heart being medial to the lungs. In contrast, lateral means farther from the midline (toward the sides), proximal means closer to the point of attachment (like the elbow being proximal to the wrist), distal means farther from the point of attachment, and anterior means toward the front of the body.
