Gluteus maximus is supplied by
Correct Answer: Inferior gluteal nerve
Description: INFERIOR GLUTEAL NERVE:- Root value:L5,S1,S2Course: Enters gluteal region through greater sciatic notch below pyriformis muscle.Branches: Gluteus maximus.It is the sole supply to the large antigravity, postural muscle with red fibers, responsible for extending hip joint. SUPERIOR GLUTEAL NERVE Root value: L4,L5,S1Course: enters the gluteal region through greater sciatic notch above pyriformis muscle. Runs between gluteus medius and gluteus minimus to end in tensor fascia lata. Branches :-it supplies 1. Gluteus medius 2. Gluteus minimus3. Tensor fascia lata SCIATIC NERVE:-Root value: L4,L5,S1,S2,S3 ventral rami Thickest nerve in the body.Terminal branch of lumbosacral plexus.Tibial pa and common peroneal pa. Tibial pa:ventral division of ventral rami of L4,L5,S1,S2,S3.Common peroneal pa: dorsal division of ventral rami of L4, L5, S1, S2. Course: arises in pelvis.Leaves pelvis by passing through greater sciatic foramen below pyriformis to enter gluteal region.In gluteal region, it lies deep to gluteus maximus and crosses superior and inferior gamellus, obturator internus, quadratus femoris to reach thigh.During its sho course it lies between ischial tuberosity and greater trochanter.Gives no branches in gluteal region. Branches:--Muscular1. From tibial pa: semitendinosus, semimembranosus, long head of biceps femoris, ischial pa of Adductor Magnus.2. From common peroneal :Sho head of biceps femoris. Aicular: hip joint Terminal:tibial and common peroneal. {Reference: BDC 6E pg no.173}
