Which directional term means closest to the point of attachment?

Which directional term means closest to the point of attachment?

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

Answer: (A)

In anatomy, directional terms describe location relative to the body or a point of attachment. Proximal means closest to the point where a limb attaches to the trunk. So, for the upper limb, the elbow is proximal to the wrist because the elbow is nearer to the shoulder (the limb’s attachment). Similarly, in the lower limb, the thigh is proximal to the knee, and the knee is proximal to the ankle. This is the opposite idea of distal, which means farther from the attachment point. Medial and lateral describe position toward or away from the body's midline, not distance to the attachment point.
