Which point lies on the medial side of the lower leg, 3 cun superior to the prominence of the medial malleolus?

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

Answer: (A)

The point described is SP6. It lies on the medial side of the lower leg, 3 cun above the prominence of the medial malleolus, along the posterior border of the tibia. This exact landmark—medial leg, a specific distance above the ankle—defines SP6, a key point on the spleen channel.

Other options don’t match that precise location: they are either situated on the foot or at different vertical positions along the leg, not at the 3-cun level above the medial malleolus on the posteromedial leg.
