Muscles; Muscular system > As the gemelli muscles (superior, inferior) are the smaller of the three and less capable of independent actions, they are considered accessory reinforcements to obturator internus. Copyright It blends with the lower part of the tendon of the Obturator internus, and is inserted with it it into the medial surface of the greater trochanter. This article will describe the anatomy and functions of the inferior gemellus muscle. Inferior gemellus is overlaid superficially by the gluteus maximus muscle, while the hip joint is located deep, or anterior, to it.

Inferior gemellus travels inferior to the tendon initially, and then passes anterior to it as they approach the insertion point on the femur. This aspect is necessary because obturator internus loses a proportion of its power once it leaves the pelvis and turns almost ninety degrees when crossing the lesser sciatic foramen. Last's Anatomy. This action is compensated by the lower femur moving laterally, resulting in thigh abduction.

It courses horizontally in a lateral direction, merging with the inferior border of the tendon of obturator internus. All content published on Kenhub is reviewed by medical and anatomy experts. When the hip, and hence the thigh, are flexed, inferior gemellus pulls the upper femur medially. It originates from the lateral surface (upper part) of ischial tuberosity, inferior to the groove occupied by the tendon of the obturator internus muscle.
