The hamstring muscles actively bend (flex) the knee. They also act to straighten or (extend) the hip (as in the motion of moving the thigh backward). Surprisingly, these large muscles are not very active with normal walking or standing. However, they are extremely important in power activities such as running, jumping, and climbing.
The hamstrings are the main group of muscles that make the knee flex. There are also other muscles that aid flexion which also rotate the knee in the medial lateral directions. There are two parts to this muscle, the long head and short head. The long head originates from the rear of the pelvis and the short head from the rear of the femur.
