Gluteus Maximus - Podcast Version 0:00 / 0:00 1x 0.25x 0.5x 0.75x 1x 1.25x 1.5x 1.75x 2x The gluteus maximus is a muscle of the gluteal region in the lower limb. It the largest and most superficial gluteal muscle. Attachments: Originates from the gluteal (posterior) surface of the ilium, sacrum and coccyx. The fibres slope across the buttock at a 45 degree angle and insert onto the iliotibial tract and gluteal tuberosity of the femur. Actions: Thigh extension. It also assists with lateral rotation of the lower limb. Innervation: Inferior gluteal nerve. Blood Supply: Superior and inferior gluteal arteries By TeachMeSeries Ltd (2026) Fig 1The superficial muscles of the gluteal region. The gluteus maximus and medius have been partly removed.

Learn More Frequent questions What is the gluteus maximus muscle? The gluteus maximus is the largest and most superficial muscle in the gluteal region of the lower limb. It plays a crucial role in thigh extension and lateral rotation. Where does the gluteus maximus originate and insert? This muscle originates from the gluteal surface of the ilium, sacrum, and coccyx, and its fibres insert onto the iliotibial tract and gluteal tuberosity of the femur. What are the primary actions of the gluteus maximus? The primary actions of the gluteus maximus include extending the thigh and assisting with the lateral rotation of the lower limb, making it vital for movements such as climbing and running. Which nerve innervates the gluteus maximus? The gluteus maximus is innervated by the inferior gluteal nerve, which is essential for its function in thigh movement. What is the blood supply to the gluteus maximus? The blood supply to the gluteus maximus comes from the superior and inferior gluteal arteries, ensuring that the muscle receives adequate nutrients and oxygen for its activities. Rate This Article
