Gemelli Muscles - Podcast Version 0:00 / 0:00 1x 0.25x 0.5x 0.75x 1x 1.25x 1.5x 1.75x 2x The superior and inferior gemelli muscles are located within the gluteal region in the lower limb. They are narrow and triangular-shaped, separated by the obturator internus tendon. Attachments: Superior gemellus muscle originates from the ischial spine Inferior gemellus muscle originates from the ischial tuberosity. They both attach onto the greater trochanter of the femur. Actions: Lateral rotation and abduction. Innervation: Superior gemellus muscle is innervated by the nerve to obturator internus Inferior gemellus is innervated by the nerve to quadratus femoris. Blood Supply: Inferior gluteal artery By TeachMeSeries Ltd (2026) Fig 1.2The deep muscles of the gluteal region.

Learn More Frequent questions What are the gemelli muscles and where are they located? The gemelli muscles, comprising the superior and inferior gemelli, are situated in the gluteal region of the lower limb. They are narrow, triangular muscles positioned adjacent to the obturator internus tendon. What are the origins of the superior and inferior gemelli muscles? The superior gemellus originates from the ischial spine, while the inferior gemellus arises from the ischial tuberosity. Both muscles insert onto the greater trochanter of the femur. What actions do the gemelli muscles perform? The gemelli muscles are responsible for lateral rotation and abduction of the hip joint. Their positioning allows them to aid in these movements effectively. How are the gemelli muscles innervated? The superior gemellus is innervated by the nerve to obturator internus, whereas the inferior gemellus receives innervation from the nerve to quadratus femoris. This innervation is crucial for their functional activity. What is the blood supply to the gemelli muscles? The blood supply to the gemelli muscles comes from the inferior gluteal artery. This vascularisation is essential for their metabolic needs and overall function. Rate This Article
