This muscle is primarily responsible for hip, torso extension, and returning from a squat position. It works hard to rise from chair. The gluteal region is located posterior to the pelvic girdle and extends distally into the upper leg Leg The lower leg, or just "leg" in anatomical terms, is the part of the lower limb between the knee and the ankle joint. Shaw popularized the myocutaneous superior gluteal artery free flap; however, a short vascular pedicle often led to additional vein grafting, thus decreasing The muscle is innervated by the ventral rami of S1 and S2 (and L5 to a lesser extent), which join to form the nerve to the piriformis. The inferior branch innervates the gluteus minimus, piriformis and tensor fascia latae.

The inferior gluteal nerve is also a motor branch of the sacral plexus, arising from the posterior divisions of the L5, S1, and S2 anterior roots. The inferior gluteal nerve leaves the pelvis through the greater sciatic foramen and runs underneath the piriformis muscle. Its primary role is in the extension and lateral rotation of the hip. inferior gluteal area and most of the posterior thigh and proximal leg. The gluteus maximus muscle .

Through what foramen does it exit the pelvis? The muscle is supplied by the inferior gluteal nerve which arises from the dorsal branches of the ventral rami of the fifth (L5), the first (S1) and second (S2) sacral nerves. The inferior gluteal nerve is the main motor neuron that innervates the gluteus maximus muscle. The sciatic nerve is a really important one and is the largest nerve to come out of the sacral plexus.

The bony structure is composed of the tibia and fibula bones, and the muscles of the leg are grouped into the anterior, lateral, and posterior compartments by extensions of . N to . ischial tuberosity. The inferior gluteal nerve has been traditionally described as a solely motor branch innervating the gluteus maximus.
