APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Gluteus maximus is one of the strongest muscles in the human body. It works with the semitendinosus and semimembranosus to extend the hip.

Detailed explanation-2: -The action of gluteus maximus extends the hip from a position of full flexion, as in climbing stairs, or rising from a squatting or sitting position.

Detailed explanation-3: -The primary hip extensors include the gluteus maximus, posterior head of the adductor magnus, and the hamstrings (TABLE 2).13, 17 In the anatomic position, the posterior head of the adductor magnus has the greatest moment arm for extension, followed closely by the semitendinosus.

Detailed explanation-4: -The gluteus maximus works with the semitendinosus and semimembranosus muscles to extend the hip. The muscle also works in conjunction with the iliopsoas, piriformis, and obturator muscles to externally rotate the hip.

Detailed explanation-5: -The gluteus medius runs underneath the gluteus maximus and the gluteus minimus is located in front (or underneath) the gluteus medius. Together, the glutes help support your hips.
