Vastus Intermedialis
O: Anterior femur
I: Tibial tuberosity via patella tendon
A: extends knee
Rectus Femoris
O: Anterior inferior iliac spine
I: Tibial tuberosity via patella tendon
A: extends knee and flexes hip
Semimembranous
O: Ischial tuberosity
I: Posterior portion of the medial tibial condyle
A: flexes knee and extends hip
Semitendinous
O: Ischial tuberosity
I: pes ancerine
A: flexes knee and extends hip
Biceps Femoris
O: Ischial tuberosity and linea aspera of femur
I: fibular head
A: flexes knee and extends hip and lateral knee rotation
Sartorius
O: Anterior superior iliac spine

O: Gluteal surface of ilium
I: Greater trochanter
A: abducts hip and medial rotation
Piriformis
O: Anterior sacrum
