APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -The primary hip extensors are the gluteus maximus and the hamstrings (i.e., the long head of the biceps femoris, the semitendinosus, and the semimembranosus).

Detailed explanation-2: -Now we’ll move on to look at the four muscles that extend the hip. The first three, which are known collectively as the hamstring muscles, act at the hip and at the knee. The fourth one, gluteus maximus, acts only at the hip.

Detailed explanation-3: -The main muscle involved in hip extension is the gluteus maximus, which is the largest muscle in your buttocks. The gluteus medius also helps with hip extension, though to a lesser extent.
