Musculus vastus intermedius

The vastus intermedius (/ˈvæstəs ˌɪntərˈmiːdiəs/) (Cruraeus) arises from the front and lateral surfaces of the body of the femur in its upper two-thirds, sitting under the rectus femoris muscle and from the lower part of the lateral intermuscular septum. Its fibers end in a superficial aponeurosis, which forms the deep part of the quadriceps femoris tendon.Right femur. Anterior surface.Right femur.
