The hamstrings in the back of the thigh consist of three separate muscles.

Hamstring muscle anatomy. The hamstring muscles have their origin where their tendons attach to bone at the ischial tuberosity of the hip often called the sitting bones and the linea aspera of the femur. The hamstrings are comprised of three separate muscles. The three hamstring muscles alone make up the classification of muscles known as the posterior compartment of the thigh.

They are the antagonistic muscles to the quads. The biceps femoris semitendinosus and semimembranosus. These muscles originate just underneath the gluteus maximus on the pelvic bone and attach on the tibia.

The hamstring tendons flank the space behind the knee. The hamstrings are found medial to the gracilis and adductor magnus and lateral to the vastus lateralis. At the back of the upper leg behind the thigh quadriceps there are three muscles known as the hamstrings.

The hamstrings refer to 3 long posterior leg muscles the biceps femoris semitendinosus and semimembranosus. Anatomy of the hamstring muscles. The most medial muscle the semimembranosus.

Because these muscles have a common site of origin on the ischial tuberosity and have similar positions in the posterior thigh they are often difficult to distinguish from each other.
