The muscle also helps stabilize the hip joint. That is usually the journal article where the information was first stated. The obturator muscles and both gemelli insert in the trochanteric fossa. Therefore, it belongs to the deep gluteal muscle group. Get Top Tips Tuesday and The Latest Physiopedia updates, The content on or accessible through Physiopedia is for informational purposes only.

Superior gemellus muscle. Please contact. It supplies a small branch to the superior gemellus muscle before continuing to pierce the medial surface of the obturator internus muscle.

The base of the superior gemellus muscle originates from the gluteal surface of the ischial spine, a thin pointed eminence that emerges from the posterior border of the ischium (the sacrospinous ligament is attached to the point of the ischial spine).

Transverse tarsal joint (Chopart's joint), Tarsometatarsal joints (Lisfranc's joint), Medial aspect of greater trochanter of femur, Internal pudendal and inferior gluteal arteries. These four muscles work with gluteus maximus to resist anterior forces of the hip. Testing of the external rotators would be done in a normal hip assessment.

Available from: I give my consent to Physiopedia to be in touch with me via email using the information I have provided in this form for the purpose of news, updates and marketing. Reference article, Radiopaedia.org. It works with gemellus inferior and obturator internus, to form the triceps coxae, to externally rotate the hip[1]. In most cases Physiopedia articles are a secondary source and so should not be used as references. The superior gemellus muscle is innervated by the nerve to obturator internus (L5, S1, S2),a branch of the sacral plexus. Kenhub - Learn human anatomy. In isolation the superior gemellus muscle is incapable of independent action however working synergistically with other external rotators of the hip, the muscle aids lateral rotation of the hip when the thigh is extended and supports abduction when the thigh is flexed. The superior gemellus muscle receives its blood supply from branches of the inferior gluteal artery. Medial surface of greater trochanter of femur, in common with obturator internus, Rotates the thigh laterally; also helps abduct the flexed thigh, Quadrangular Space, Triangular Space, Triangular Interval, Cards - Algorithmic Flashcards by Orthobullets, Global Orthopaedic Benchmark Exam (GLOBE). hbbd``b`J @q`$d-&Fe YF /

.v#^#Bt[F 6;dR"JTIU The superior and inferior gemellus muscles are closely related to the obturator internus muscle. The superior gemellus muscle travels almost horizontally to insert in to the middle part of the medial aspect of the greater trochanter, known as the trochanteric fossa, which is a smooth faceted area of bone bounded posteriorly by the intertrochanteric crest.

ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. hb```f``ba`b`4ed@ A3GE The superior gemellus (Latin: musculus gemellus superior) is a small triangular-shaped pelvic muscle that stretches between the ischium of the hip bone and femur. The gemelli muscles act to externally (laterally) rotate the hip. It is located inferior to the gluteal muscles and deep within the posterior pelvis. Physiopedia is not a substitute for professional advice or expert medical services from a qualified healthcare provider. The superior gemellus muscle lies directly inferior to the piriformis muscle and above the obturator internus muscle. Mcminn. 
Thank you. 
Inferior gluteal and internal pudendal arteries. 
Together with its twin: gemellus inferior as well as obturator internus and piriformis, gemellus superior is a deep stabiliser of the hip joint. When refering to evidence in academic writing, you should always try to reference the primary (original) source. V3,j !u2fbV$^L&@| 7

Shinohara H. Gemelli and Obturator Internus Muscles: Different Heads of One Muscle? It is difficult to assess gemellus superior in isolation due to its proximity to the other external rotators of the hip. 
Gray's Anatomy for Students. The superior gemellus inserts on the medial aspect of the greater trochanter (of the femur) via the tendon of the obturator internus muscle. The superior gemelus is innervated by the nerve to obturator internus (L5 - S2) that arises from the sacral plexus. The nerve exits the pelvis via the greater sciatic foramen inferior to the piriformis muscle and typically between the posterior cutaneous nerve of the thigh and the pudendal nerve. Nerve to obturator internus, which is formed from portions of the L5, S1, and S2 spinal nerves. [2], Gemellus superior originates from the outer (gluteal) surface of the spine of theischium[3], It has a blended insertion with the upper part of the tendon of theObturator internus.[3]. Functions of the gemelli muscles (preview) - 3D Human Anatomy | Kenhub. Together these muscles act primarily to laterally rotate the extended thigh and are also hip stabilizers steadying the femoral head in the acetabulum. [5].

The superior gemellus muscle is a small triangular muscle in the gluteal region that together with the inferior gemellus and obturator internus muscles form the tricipital (three headed) triceps coxae which occupies the space between the piriformis muscle (superiorly) and quadratus femoris muscle (inferiorly). posterior suprapatellar (prefemoral or supratrochlear) fat pad, anterior suprapatellar (quadriceps) fat pad, accessory anterior inferior tibiofibular ligament, superficial posterior tibiotalar ligament, superficial posterior compartment of the leg (calf), accessory extensor digiti secundus muscle, descending branch of the lateral circumflex, hip stabilizer (helps steady femoral head in acetabulum), 1. Anatomy Next 2022. Both are branches of the internal iliac artery. The small gemelli are narrow triangular extraperitoneal muscles that may be considered as reinforcements of the obturator internus muscle. For questions regarding business inquiries. Unable to process the form. The superior gemellus muscle receives arterial blood supply from the internal pudendal and inferior gluteal arteries. Richard Lee Drake, Henry Gray, Wayne Vogl et al. Also, as the superior gemellus provides external (lateral) rotation of the thigh, it is classified as one of the lateral rotators.
