Quadratus Femoris - Podcast Version 0:00 / 0:00 1x 0.25x 0.5x 0.75x 1x 1.25x 1.5x 1.75x 2x The quadratus femoris is a muscle of the gluteal region in the lower limb. It is the most inferior of the deep gluteal muscles, located below the gemelli and obturator internus. Attachments: Originates from the lateral aspect of the ischial tuberosity and attaches to the quadrate tuberosity on the intertrochanteric crest. Actions: Lateral rotation of the lower limb. Innervation: Nerve to quadratus femoris. Blood Supply: Inferior gluteal artery and medial circumflex femoral artery By TeachMeSeries Ltd (2026) Fig 1The deep muscles of the gluteal region.

Learn More Frequent questions What is the quadratus femoris muscle? The quadratus femoris is a deep muscle in the gluteal region of the lower limb, situated inferiorly to the gemelli and obturator internus muscles. It plays a key role in the lateral rotation of the lower limb. Where does the quadratus femoris originate and insert? This muscle originates from the lateral aspect of the ischial tuberosity and inserts at the quadrate tuberosity on the intertrochanteric crest of the femur. These attachments allow it to effectively perform its functions. What is the primary action of the quadratus femoris? The primary action of the quadratus femoris is to facilitate lateral rotation of the lower limb. This movement is crucial for various activities, including walking and changing direction. Which nerve innervates the quadratus femoris? The quadratus femoris is innervated by the nerve to quadratus femoris. This nerve provides the necessary motor function for the muscle's actions. What is the blood supply to the quadratus femoris muscle? The blood supply to the quadratus femoris comes from the inferior gluteal artery and the medial circumflex femoral artery. These vessels ensure the muscle receives adequate oxygen and nutrients for its function. Rate This Article
