(Quadriceps Femoris) Vastus Medialis

Muscle Origin

Linea aspera to tibial tuberosity.

The (Quadriceps Femoris) Vastus Medialis attaches to the distal ½ of the intertrochanteric line, to the proximal part of the medial supracondylar line, to the medial intermuscular septum, and to the tendon of the adductor magnus. American Academy of Manual Madicine.

Insertion

Quadriceps tendon.

Into the medial side of the quadriceps tendon joining with the rectus femoris and the other vasti muscles, enveloping the patella, then by the patellar ligament into the tibial tuberosity. The insertion attachment points are the large Quadricep tendon which is an aponeurosis which covers about half of the lower shaft of the femur and merges into the supra patella tendon as well as the laurel borders of the patella. Muscles Used
