Which term describes a position closer to the midline than another structure?

• A. Midline
• B. Medial
• C. Lateral Recumbent
• D. Proximal

Answer: (B)

Medial describes being closer to the midline, the imaginary vertical line that splits the body into left and right halves. If one structure lies nearer to that line than another, it is medial. For example, the medial malleolus is closer to the midline than the lateral malleolus. The other terms don’t describe proximity to the midline: midline is just the reference line itself; lateral recumbent is a body position (lying on the side); proximal refers to closeness to the trunk or point of origin, not to the midline.
