Which point is on the medial side of the lower leg, 3 cun superior to the prominence of the medial malleolus, in a depression close to the medial crest of the tibia?

• A. SP 5
• B. SP 7
• C. SP 6
• D. SP 8

Answer: (C)

The line of reasoning here relies on precise land-marks along the spleen channel on the medial leg. The point is located on the medial aspect of the lower leg, about three cun above the prominence of the medial malleolus, in a hollow that lies close to the medial crest of the tibia. That exact spot is Spleen 6. The tibial crest and the small depression just behind it are the key landmarks that distinguish this point from others along the channel.

So this is the best answer because it matches the described location: medial leg, 3 cun above the medial malleolus, in the hollow near the tibial crest. The other options lie at different spots along the channel or different parts of the ankle/foot and do not correspond to these landmarks.
