The thigh is proximal to the knee. Which term describes this relationship?

• A. Proximal
• B. Distal
• C. Superficial
• D. Deep

Answer: (A)

This question tests understanding of how directional terms describe location along a limb. Proximal means closer to the point of attachment to the trunk, while distal means farther away from that attachment. The thigh sits closer to the hip (the body's trunk) than the knee does, so the thigh is proximal to the knee. Superficial and deep describe how close something is to the body surface, not its position relative to the trunk, so they don’t describe this relationship. Distal would place the knee farther from the trunk, which is the opposite of the statement.
