The entire quadriceps femoris muscle is innervated by the femoral nerve (L2-L4) Musculus quadratus femoris är en muskel i höften, och är en av sex muskler i lateralrotationsgruppen.. Muskeln har sitt ursprung i tuberositas ischiadica laterala kant och fäster i tuberculum quadratum på crista intertrochanterica och inferiort om denna på lårbenet.Muskeln roterar låret lateralt. Muskeln innerveras av nervus musculi quadrati femoris (som går vidare till lumbarnerven.

the quadratus femoris. CONCLUSION. Lesions of the quadratus femoris have been implicated as a cause of hip pain. It therefore is important to be familiar with the anatomy of the quadratus muscle and to be able to diagnose the causes of abnormal signal intensity in the quadratus femoris, which include tears and impingement.

When pronator quadratus contracts, it pulls the lateral side of the radius towards the ulna, thus pronating the hand. Its deep fibers serve to keep the two bones in the forearm bound together. Moreover, this muscle can be absent in some humans, however, that does not affect the action of pronation very notably, as the pronator teres does the major role in that action accessory innervation of other branches often arise from the nerves to muscles overlying the hip joint (Kawaguchi et al .; Bhatia et al .).
