The hamstrings refer to 3 long posterior leg muscles the biceps femoris semitendinosus and semimembranosus. As group these muscles act to extend at the hip and flex at the knee. The hamstrings flex the knee joint adduct the leg and extend the thigh to the backside of the body.

Semimembranosus and semitendinosus apart from the short head of biceps femoris the muscles share two common features. Muscle will participate in flexion of the knee. Muscles will be innervated by the tibial branch of the sciatic nerve.

Muscles should originate from ischial tuberosity. Usually a bit of midmuscle discomfort on the back of the thigh wont cause problems. Originate from the ischial tuberosity.

Some anatomists consider the adductor magnus muscle to be a hamstring muscle but for the purposes of this review it will not be considered as such. The semitendinosus lies superficial to the semimembranosus though the semimembranosus is so wide that part of it is left uncovered on either side of semitendinosus. The hamstrings are a group of muscles and their tendons at the rear of the upper leg.

The semitendinosus muscle is located between the semimembranosus. Muscles should be inserted over the knee joint in the tibia or in the fibula. These muscles originate just underneath the gluteus maximus on the pelvic bone and attach on the tibia.
