Los músculos gemelos superior e inferior se localizan en la región glútea de la extremidad inferior. Son estrechos y de forma triangular, separados por el tendón del obturador interno. Inserciones: El músculo gemelo superior se origina en la espina ciática. El músculo gemelo inferior se origina en la tuberosidad isquiática. Ambos se insertan en el trocánter mayor del fémur. Acciones: rotación lateral y abducción. Inervación: El músculo gemelo superior está inervado por el nervio del obturador interno. El gemelo inferior está inervado por el nervio del cuadrado femoral. Irrigación sanguínea: arteria glútea inferior. By TeachMeSeries Ltd (2026) Fig. 1.2: los músculos profundos de la región glútea.

Learn More Frequent questions What are the locations of the superior and inferior gemellus muscles? The superior and inferior gemellus muscles are situated in the gluteal region of the lower limb. They are narrow and triangular in shape, positioned adjacent to the tendon of the obturator internus. Where do the gemellus muscles originate and insert? The superior gemellus muscle originates from the ischial spine, while the inferior gemellus muscle arises from the ischial tuberosity. Both muscles insert into the greater trochanter of the femur. What actions do the gemellus muscles perform? The gemellus muscles are responsible for lateral rotation and abduction of the thigh. These actions are important for movements involving the hip joint. How are the gemellus muscles innervated? The superior gemellus muscle is innervated by the nerve to the obturator internus, whereas the inferior gemellus muscle receives innervation from the nerve to the quadratus femoris. This innervation is crucial for muscle function. What is the blood supply for the gemellus muscles? The blood supply to the gemellus muscles is primarily provided by the inferior gluteal artery. This vascularisation supports their metabolic needs during movement. Valora este artículo
