The semitendinosus is a fusiform muscle in the posterior compartment of the thigh and hamstrings muscles. It is often divided into two parts by a tendinous inscription 2. It accompanies the semimembranosus muscle in the medial aspect of the posterior thigh. It is named for its cord-like tendon which forms half way down the thigh.
Summary
- origin: ischial tuberosity
- insertion: as part of the pes anserine tendon, onto the medial superior tibia
-
action
- flexes knee joint
- medially rotates knee joint (when the knee is flexed beyond 90°)
- extends hip joint (less than biceps femoris)
-
arterial supply
- inferior gluteal artery
- perforating arteries
- popliteal artery
- innervation: tibial nerve
- antagonist: quadriceps
