Latinmusculus articularis genus

Origin:femur
Insertion:suprapatellar bursa
Artery:femoral artery
Nerve:femoral nerve
Action:Pulling the suprapatellar bursa during extension of the knee.
Dorlands/Elsevier m_22/12548413
The Articularis genu (Subcrureus) is a small muscle, usually distinct from the Vastus intermedius, but occasionally blended with it; it arises from the anterior surface of the lower part of the body of the femur, and is inserted into the upper part of the synovial membrane of the knee-joint.

Articularis genu pulls the suprapatellar bursa during extension of the knee, allowing the patella to move freely without friction with the femur.

It sometimes consists of several separate muscular bundles.

The term Iliopsoas refers to the combination of three muscles:
  • psoas major
  • psoas minor
  • iliacus
These muscles are distinct in the abdomen, but in the thigh, they are usually indistinguishable, and so in that context, they are usually given a common name.
