The gluteal tuberosity is the lateral prolongation of three prolongations of the linea aspera that extending superior-ward from the superior extremity of the linea aspera [1] on the posterior surface of the femur. [2] The gluteal tuberosity takes the form of either an elongated depression [3] or a rough ridge.
The gluteus medius is a broad, thick, radiating muscle, situated on the outer surface of the pelvis. It lies profound to the gluteus maximus and its posterior third is covered by the gluteus maximus, its anterior two-thirds by the gluteal aponeurosis, which separates it from the superficial fascia and skin. The gluteus minimus is the smallest ...
The gluteal muscles include the gluteus maximus, gluteus medius, gluteus minimus, and tensor fasciae latae.They cover the lateral surface of the ilium.The gluteus maximus, which forms most of the muscle of the buttocks, originates primarily on the ilium and sacrum and inserts on the gluteal tuberosity of the femur as well as the iliotibial tract, a tract of strong fibrous tissue that runs ...
Above, the linea aspera is prolonged by three ridges. The lateral ridge is very rough, and runs almost vertically upward to the base of the greater trochanter.It is termed the gluteal tuberosity, and gives attachment to part of the gluteus maximus: its upper part is often elongated into a roughened crest, on which a more or less well-marked, rounded tubercle, the third trochanter, is ...
gluteal tuberosity of femur, iliotibial tract: superior gluteal artery, inferior gluteal artery: inferior gluteal nerve (L5, S1, S2 nerve roots) externally rotates and extends hip joint, supports extended knee through iliotibial tract, chief antigravity muscle in sitting: Iliacus, psoas major, psoas minor: 2 1 gluteus medius: Lower limb ...
The lateral ridge termed the gluteal tuberosity is very rough, and runs almost vertically upward to the base of the greater trochanter. It gives attachment to part of the gluteus maximus: its upper part is often elongated into a roughened crest, on which a more or less well-marked, rounded tubercle, the third trochanter, is occasionally developed.
In other primates, the correlate to the human gluteus maximus consists of the ischiofemoralis, a small muscle that corresponds to the human gluteus maximus and originates from the ilium and the ligaments of the sacroiliac, and the gluteus maximus proprius, a large muscle that extends from the ischial tuberosity to a relatively more distant ...
The gluteus maximus is primarily an extensor and lateral rotator of the hip joint, and it comes into action when climbing stairs or rising from a sitting to a standing posture. Furthermore, the part inserted into the fascia latae abducts and the part inserted into the gluteal tuberosity adducts the hip.
