Human Anatomy; the gluteal region - summary
The gluteal region can be divided into the gluteal muscles and the lateral rotators, which have separate functions.
The gluteal muscles, (gluteus maximus, gluteus medius and gluteus minimus) can be further divided, since gluteus maximus assists in different actions from the other gluteal muscles.
Gluteus medius and minimus both insert onto the greater trochanter (medius laterally and minimus anteriorly); both abduct and medially rotate the thigh, as well as stabilising during locomotion; both are served by the superior gluteal nerve, and both are served by the superior gluteal artery.
The lateral rotators all, to no one's surprise, laterally rotate the femur. Piriformis also aids in abduction, and obturator externus stabilise the femoral head in the acetabulum.
The first group (piriformis, obturator internus, and the gemelli) all insert onto the greater trochanter of the femur. The gemelli and quadratus femoris share origins on the ischium, and the nerves are nerve to piriformis (piriformis), the nerve to obturator internus (superior gemellus and obturator internus) and the nerve to quadratus femoris (inferior gemellus and quadratus femoris).
