Which Nerves Innervate Sartorius?

The sartorius is supplied by the femoral nerve

. It is a flexor of the hip and knee and also, along with other long muscles connecting the hip bone to the leg, balances the hip bone on the femur.

What nerve Innervates the Pectineus?

Pectineus is predominately innervated by the femoral nerve (L2, L3)]. However, in some people pectineus may receive innervation from two separate nerves of the lumber plexus. This composite innervation reflects the dual compartmentalisation of pectineus into both the anterior and medial compartments of the thigh.

What movement does the sartorius perform?

Function. At the hip it flexes, weakly abducts, and rotates the thigh laterally. At the knee, it can flex the leg; when the knee is flexed, it also rotates the leg medially. This muscle plays an important part in stabilisation of the pelvis—especially in women.
