Which point lies on the medial side of the foot, distal and inferior to the medial malleolus, in the depression distal and inferior to the navicular tuberosity?

• A. KD 1
• B. KD 3
• C. KD 2
• D. BL 66

Answer: (C)

The position described is a point on the Kidney channel located on the medial side of the foot, in the hollow distal and inferior to the navicular tuberosity. This exactly matches KD2, which sits in the depression distal and inferior to the navicular tuberosity along the medial arch of the foot. KD3 would be behind the medial malleolus in the ankle groove, not in that navicular region. KD1 is on the sole, not on the medial side near the navicular tuberosity. BL66 lies on the bladder channel on the lateral side of the foot, not medially. Thus the described location is KD2.
