1Where is Biguan?

On the front of the thigh, in the hollow framed by three muscles: the upper rectus femoris, the sartorius and the tensor fasciae latae.

Reference: where the line from the anterior superior iliac spine to the lateral end of the patellar base crosses the level of the lower border of the pubic symphysis.

Beneath the point

Rectus femoris muscle · Sartorius muscle · Tensor fasciae latae

Our 3D measurement · In our 3D model: skin at the level of the lower border of the pubic symphysis, centred on the 17.6 mm gap between the tensor fasciae latae and the sartorius (over the rectus femoris).

2How do I find it on my body?

Bend the hip and knee slightly.
Open the thigh a little and push its inner front against resistance; a triangular hollow appears.
See the rectus femoris running down between the sartorius (inside) and the tensor fasciae latae (outside).
Press the deepest dip just below the triangle's apex.

Check · it matches where the ASIS–patellar-base line crosses the level of the pubic symphysis's lower border.

📖 Words explained

tensor fasciae latae: A short muscle on the outer front of the pelvis. It pulls tight the tough band on the outer thigh (iliotibial tract).
rectus femoris: The muscle running straight down the middle of the front of the thigh. It starts on the pelvis, joins the kneecap tendon, straightens the knee and lifts the leg.
pubic symphysis: Where the two pubic bones join with cartilage at the bottom middle of the belly; going straight down from the navel you meet it as a hard bony edge. The center of the navel to its upper edge is taken as 5 cun.
