Vastus medialis is one of the four muscles that make up the quadriceps group of muscles.

Vastus medialis origin and insertion and action. The vastus medialis arises medially along the entire length of the femur and attaches with the other. Origin insertion action innervation. Nerve posterior division of femoral nerve l3 4.

Attachments of vastus medialis muscle. Lower intertrochanteric line spiral line medial lineaaspera and medial intermuscular septum. Quadriceps tendon to base of patella and onto tibial tuberosity via the patellar ligament.

Into the medial side of the quadriceps tendon joining with rectus femoris vastus lateralis and vastus intermedius muscles enveloping the patella then by the patellar ligament into the tibial tuberosity. Medial base and border of patella. Lower part of the intertrochanteric line along the spiral line to the medial lip of the linea aspera and the medial intermuscular septum and the aponeurosis of adductor magnus.

The vastus medialis originates from the intertrochanteric line on the inner part of your thigh bone femur. Insertion quadriceps tendon to patella via ligamentum patellae into tubercle of tibia. The others are the vastus lateralis vastus intermedius and rectus femoris.

Also forms the medial patellar retinaculum and medial side of quadriceps femoris tendon. Inferior portion of intertrochanteric line spiral line medial lip of linea aspera superior part of medial supracondylar ridge of femur and medial intermuscular septum insertion. Origin anterior and lateral shaft of femur.

The vastus medialis is a muscle present in the anterior compartment of thigh and is one of the four muscles that make up the quadriceps muscle. It is the most medial of the vastus group of muscles. From there it courses down the front and inner portion of the kneecap patella and joins the other quadriceps muscles rectus femoris vastus intermedius and vastus lateralis.

Medial quadriceps tendon to patella and directly intomedial patella via ligamentum patellae into tubercle of tibia.
