Question

What muscle works as a force couple with the hip extensors?

a) Iliopsoas
b) Tensor fasciae latae
c) Rectus femoris
d) Gluteus medius

Answer 1

The muscle that works as a force couple with the hip extensors is the Tensor fasciae latae (TFL). It acts as a synergist of the gluteus medius and iliopsoas in flexing and abducting the thigh. It also helps stabilize the lateral aspect of the knee.

Step-by-step explanation:

The muscle that works as a force couple with the hip extensors is the Tensor fasciae latae (TFL).

The TFL is a muscle located in the superior aspect of the lateral thigh. It acts as a synergist of the gluteus medius and iliopsoas in flexing and abducting the thigh. It also helps stabilize the lateral aspect of the knee by pulling on the iliotibial tract (band), making it taut.
