- Semitendinosus muscle
Semitendinosus muscle Muscles of the gluteal and posterior femoral regions. Semitendinosus labeled at bottom left. Semitendinosus visible at bottom left. Latin musculus semitendinosus Gray's subject #128 479 Origin tuberosity of the ischium Insertion pes anserinus Artery inferior gluteal artery, perforating arteries Nerve sciatic (tibial, L5, S1, S2) Actions flex knee, extend hip joint Antagonist Quadriceps muscle
It arises from the lower and medial impression on the tuberosity of the ischium, by a tendon common to it and the long head of the biceps femoris; it also arises from an aponeurosis which connects the adjacent surfaces of the two muscles to the extent of about 7.5 cm. from their origin.
The muscle is fusiform and ends a little below the middle of the thigh in a long round tendon which lies along the medial side of the popliteal fossa; it then curves around the medial condyle of the tibia and passes over the tibial collateral ligament of the knee-joint, from which it is separated by a bursa, and is inserted into the upper part of the medial surface of the body of the tibia, nearly as far forward as its anterior crest.
At its insertion it gives off from its lower border a prolongation to the deep fascia of the leg and lies behind the tendon of the sartorius, and below that of the gracilis, to which it is united. These three tendons form what is known as the pes anserinus, so named because it looks like the foot of a goose.
A tendinous intersection is usually observed about the middle of the muscle.
The semitendinosus is innervated by the tibial part of the sciatic nerve.
