Definition
| Three hamstrings all arise from the ischial tuberosity. All hamstring muscles extend the thigh and flex the leg. All are innervated by the tibial division of the sciatic nerve except for the biceps femoris short head. When knee flexion is held by the action of quadriceps, the hamstrings extend the hip, which is the action that propels forward in normal walking. |

Thick flat sheet overlying the hamstrings.
Origin- Back of the ilium, dorsal surface of sacrum and sacrotuberous ligament.
Insertion- Iliotibial tract and gluteal tuberosity of femur.
Innervation- Inferior gluteal nerve
