Which BL point is located on the back of the knee, 1 cun superior to BL39, on the medial side of the tendon of biceps femoris?

• A. BL 37
• B. BL 39
• C. BL 38
• D. BL 40

Answer: (C)

The main idea is matching a precise knee-region location to the correct Bladder point. Behind the knee, in the popliteal area, BL38 sits 1 cun above BL39 and to the medial side of the tendon of the biceps femoris. So the described spot—back of the knee, 1 cun above BL39, medial to that tendon—fits BL38 exactly. The other points lie in different spots around the knee and do not match this specific location, so they aren’t correct for this description. When locating, picture the popliteal fossa, identify the tendons of the hamstrings, then move upward one cun and toward the middle to find BL38.
