Muscles in the Inguinal Region:
TRIP Mnemonic

T=Tensor fasciae latae
R=Rectus femoris



The green line is the horizontal reference line along which the TRIP muscles are found. The sartorius muscle, labeled on the right side of the image, lies anterior to this line and to the muscles along it.

A single line in any axial section may not traverse all these muscles in a given individual, but the muscles are almost always found within one or two sections in the corresponding positions from the section in which the iliopsoas most prominently contacts the anterior neck of the femur.
