Which BL point is at the back of the knee, in the popliteal crease, in a depression midway between the tendons of the biceps femoris and semitendinosus?

Which BL point is at the back of the knee, in the popliteal crease, in a depression midway between the tendons of the biceps femoris and semitendinosus?

• A. BL 40
• B. BL 36
• C. BL 41
• D. BL 42

Answer: (A)

The line of the bladder channel on the back of the knee is captured by a single, well-defined spot: the center of the popliteal crease, right between the tendons of the biceps femoris laterally and the semitendinosus medially. This point, known as Weizhong, is the He-sea point of the Bladder channel. Its precise location at the mid-point of the popliteal fossa makes it the best match for the description. Because it’s the midpoint of the knee crease, it’s commonly used for knee and lower-leg issues and to clear damp-heat from the Bladder channel. The other options refer to different Bladder points that don’t sit at this popliteal crease location, so they don’t fit the description as closely.
