Articularis genus muscle
Template:Short description Script error: No such module "Infobox".Template:Template otherScript error: No such module "Check for unknown parameters".Script error: No such module "Check for unknown parameters". The articularis genus (also known as the subcrureus muscle[1]) is a small skeletal muscle located anteriorly on the thigh just above the knee.
Structure
It arises from the anterior surface of the lower part of the body of the femur,[2] deep to the vastus intermedius,[3] close to the knee and from the deep fibers of the vastus intermedius.[2]
Its insertion is on the synovial membrane of the knee-joint.[2]
Blood supply
It is supplied by the lateral femoral circumflex artery.[2]
Innervation
It is innervated by branches of the femoral nerve (L2-L4).[2]
Variation
Flat, wispy and highly variable,[4] sometimes consisting of several separate muscular bundles,[5] this muscle is without a distinct investing fascia and ranges 1.5–3 cm in width.[4]
It is usually distinct from the vastus intermedius, but occasionally blended with it.[5]Script error: No such module "Unsubst".Script error: No such module "Check for unknown parameters".
Function
Articularis genus pulls the suprapatellar bursa superiorly during extension of the knee,[3] and prevents impingement of the synovial membrane between the patella and the femur.[2]
