Quadriceps Strengthening Exercises

Quadriceps muscle is actually made up of 4 muscles viz.

Rectus Femoris

Vastus Medialis

Vastus Intermedialis

Vastus Lateralis

ORIGIN AND INSERTION

Rectus Femoris Originates from Anterior inferior iliac spine and the exterior surface of the bony ridge which forms the groove on the iliac portion of the acetabulum and Inserts in the base of patella in the patellar tendon as one of the four quadriceps muscles.

Vastus Medialis Originates from medial side of femur and Inserts into medial border of patella.

Vastus Intermedialis Originates 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 and Inserts in the deep part of quadriceps tendon.

Vastus Lateralis Originates from the Greater trochanter, Intertrochanteric line, and Linea aspera of the Femur and Inserts in the patella via quadriceps tendon and tibial tuberosity via patellar ligament.
