Vastus Medialis

The vastus medialis muscle is one of the four quadriceps muscles and is also known as the teardrop muscle.

Anatomy of the Vastus Medialis

The main nerves and artery that are located in the vastus medialis muscle are the femoral artery and the femoral nerve.

The vastus medialis muscle arises from the lower half of the intertrochanteric line, the medial lip of the linea aspera, the upper part of the medial supracondylar line, the tendons of the Adductor longus and the Adductor magnus and the medial intermuscular septum.

Its fibers are directed downward and forward, and are mainly attached to an aponeurosis which lies on the deep surface of the muscle and is inserted into the medial border of the patella and the Quadriceps femoris tendon.

Functions of the Vastus Medialis muscle

The main function of the vastus medialis is to extend the leg. Together with the other vasti muscles; they work in a coordinated manner to control the extension of the knee.

Medical practitioners often insist on improving the strength of this muscle especially in the treatment of anterior knee pain. The common exercise to do this is doing lunges to target this particular muscle.
