Quadratus Femoris

Quadratus Femoris The structure indicated is the quadratus femoris muscle. The quadratus femoris muscle is one of the muscles of the gluteal region. The muscles in the gluteal region are divided into a superficial and deep group. There are four muscles of the superficial group: Gluteus maximus Gluteus medius Gluteus minimus Tensor fasciae latae There are 5 muscles in the deep group: Gemellus superior Gemellus inferior Quadratus femoris Piriformis Obturator internus The deep muscles of the thigh are much smaller than the superficial group of muscles and generally serve to laterally rotate the femur at the hip joint. The quadratus …

Gemellus Superior

By Dr Peter de Souza

Gemellus Superior The structure indicated is the gemellus superior. The gemellus superior muscle is one of the muscles of the gluteal region. The muscles in the gluteal region are divided into a superficial and deep group. There are four muscles of the superficial group: Gluteus maximus Gluteus medius Gluteus minimus Tensor fasciae latae There are 5 muscles in the deep group: Gemellus superior Gemellus inferior Quadratus femoris Piriformis Obturator internus The word gemellus comes from the Latin “gemelli” which means “twins”. There are therefore two gemelli muscles, the gemellus superior, and the gemellus inferior. The gemelli muscles are located either …
