What is Semitendinosus?

Semitendinosus is muscles placed on the back of the human thigh. Together with semimembranosus and biceps femoris it is one of the three muscles of hamstrings. The long and narrow muscle, which stretches vertically from the underside of the pelvis to just below the knee, is found on the inside of the larger biceps femoric muscle on the back of the thigh. He is responsible for the movements of both hip and knee joints because it helps glual muscles in the extension of the hip and is also flexor knee. In addition, it contributes to the lower effect of media or internal rotation of the knee joint. Specifically, the Semitendinosus arises from the upper part of the ischial tuberosity on its lower inner aspect. It shares this point of origin with a long head of biceps femoris muscle next to him, with which it comes from a common tendon.

from this point on the bottom of the pelvis Semitendinosus extends about two -thirds of the way down along the back of the thighKNA narrows to form a long tendon. This tendon passes inside the rear knee parallel to the sartorius tendons and gracilis of the inner thigh muscles. Exceeding the media condyle of the tibia, one of the two rounded pardonings on the upper part of the tibia bone, connects to the inner aspect of the bone shaft just below the knee.

The

part of the tendon of the Semitendinosus exceeds this insertion point and merges with sections of the sartorius tendon and gracilis. These cuts are attached to the deep fascia of the foot, the fibrous tissue that separates the muscles of the lower leg into the compartments. Together, three are referred to as a dog anserinus as their similarity to the goose leg.

Semitendinosus is stronger in its kneeling joint than on the hips, because its insertion of the tendon directly passes through the knee. It helps biceps femoris in bending or bending the knee, especially when the hip is stretched thigh behind the body. Although it is involved in the extension of the hip and its effect becomes dominant in individuals with weak glutes, this oneMovement performs the gluteal muscles in the hip joint.
