Gluteus maximusus

Gluteus gluteus , m. Gluteus maximus, in shape approaching the rhombus. The muscle is coarse-grained, powerful, flat and reaches a thickness of 2-3 cm; Overlaps a large spit, as well as the remaining muscles of this group. It starts from the back of the external surface of the ilium , posteriorly from the posterior gluteal line, from the lateral edge of the sacrum and coccyx and from the sacro-ligamentous ligament . Muscular bundles stretch obliquely downward and laterally and are attached by their upper fascicles to the broad fascia, which passes into the iliac-tibial tract, and the lower ones to the gluteal tuberosity of the femur ; Here between the large spit and the muscle there is a sternum bag of the gluteus maximus, bursa trochanterica m. Glutei maximi. Somewhat lower along the gluteal tuberosity, between the tendon of the gluteus maximus and the upper transverse bundles of the large adductor muscle, there are two, one on top of the other, small intermuscular bags of the gluteal muscles, bursae intermusculares mm. Gluteorum. In addition, between the outer surface of the ischial hillock and the large gluteus muscle surrounding it, at the attachment site of the tendons of the long head of the biceps femoris and the semitendinous muscle, the sciatic bag of the gluteus maximus is located, bursa ischiadica m. Glutei maximi.

Function: Straightens the bent forward trunk, unbends the thigh, simultaneously penetrating it, and also stretches the wide fascia of the thigh.

Innervation: n. Gluteus inferior (plexus sacralis) [LV, SI (SII)].

Blood supply: aa. Giuteae superior et inferior, circumflexa femoris medialis, profunda femoris (perforans).
