Gluteus Maximus

Muscle Origin

Posterior iliac crest/sacrum/coccyx to gluteal tuberosity.

From a broad area on the posterior surface of the ilium, the posterior gluteal line, the rough area of bone superior and inferior to this line, upward to the iliac crest, the aponeurosis of erector spinae, the dorsal surface of the lower part of the sacrum and the side of the coccyx, the sacrotuberous ligament, and the fascia that covers gluteus medius.anatomy-model-muscles-back-040-edited

Insertion

Gluteal tuberosity of the femur and iliotibial tract.

The gluteus maximus has two insertions: those forming the upper and larger portion of the muscle, together with the superficial fibers of the lower portion, end in a thick tendinous lamina, which passes across the greater trochanter, and inserts into the iliotibial band of the fascia lata; the deeper fibers of the lower portion of the muscle are inserted into the gluteal tuberosity between the vastus lateralis and adductor magnus. Wiki

Action

Extends thigh at hip.

External rotation and extension of the hip joint, supports the extended knee through the iliotibial tract, chief antigravity muscle in sitting and abduction of the hip.

Innervation – Nerve control

Inferior gluteal nerve (L5, S1 and S2 nerve roots).

The inferior gluteal nerve is the main motor neuron that innervates the gluteus maximus muscle. Wiki

Artery

Superior and inferior gluteal arteries.

The superior gluteal artery is the largest branch of the internal iliac artery, and appears to be the continuation of the posterior division of that vessel. Wiki The inferior gluteal artery is a branch of the anterior division of the internal iliac artery.

Antagonist muscles

Iliacus, psoas major and psoas minor.
