Inferior gemellus then inserts into the medial surface of the greater trochanter of femur via this tendon. Last's Anatomy. The combination of thigh external rotation and abduction from a flexed hip has important functions in our everyday lives. After obturator internus exits the pelvis through the lesser sciatic foramen, inferior gemellus forms a muscular canal for its tendon. Gray's Anatomy for Students: With STUDENT CONSULT Online Access, 3e. (accessed on 22 Jul 2022) https://doi.org/10.53347/rID-44264. 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. Clinically Oriented Anatomy.

We'll assume you're ok with this, but you can opt-out if you wish. 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.

Register now It is part of a larger, tricipital (three-headed) muscle complex called triceps coxae (triceps of the hip) which also includes the superior gemellus and obturator internus muscles. :). Some of them require your consent. Contraction of inferior gemellus aids with external rotation and abduction of the thigh (the latter only from thigh flexion).
It also maintains the stability of the head of femur inside the acetabulum of coxal bone. After vascularizing the muscle, the medial circumflex femoral artery continues further to supply the neck of femur. The gemellus inferior and superior are a pair of triangular muscles associated with the upper and lower margins of the obturator internus tendon. This action is compensated by the lower femur moving laterally, resulting in thigh abduction.

The nerve to quadratus femoris descends deep to inferior gemellus after exiting the pelvis through the greater sciatic foramen. When the thigh is in an anatomical position, it pulls the greater trochanter of femur posteriorly, around the bones longitudinal axis, causing external (lateral) rotation of the thigh. The Gemelli are two small muscular fasciculi, accessories to the tendon of the Obturator internus which is received into a groove between them.The Gemellus inferior arises from the upper part of the tuberosity of the ischium, immediately below the groove for the Obturator internus tendon. The Inferior Gemellus is a member of the Deep Lateral Rotator Group (also known as the Deep 6), composed of the following six muscles (from superior to inferior): NOTE: The distal tendon of the inferior gemellus usually blends with the distal tendons of the superior gemellus and obturator internus. Anatomy and human movement: structure and function (6th ed.). Inferior gemellus is overlaid superficially by the gluteus maximus muscle, while the hip joint is located deep, or anterior, to it. They stabilize the trunk in a sitting position during side to side jerking and help with squatting and crawling. Necessary cookies are absolutely essential for the website to function properly. Inferior gemellus forms part of the triceps coxae muscle complex, which is located in the deep layer of the gluteal region between the piriformis and quadratus femoris muscles.

Last reviewed: July 19, 2022 These actions allow you to move sideways when seated and to swing your lower extremity sideways when stepping outside of a car. This article will describe the anatomy and functions of the inferior gemellus muscle. Inferior gemellus extends from the ischium of coxal bone until the greater trochanter of femur, hence it is sometimes referred to as an inner hip muscle.
