Etymology

Semitendinosus comes from the Latin parts semi- ('half') and tendin- (from tendon, 'a strong cord that joins muscle to bone'), a neat image of a muscle with a long tendon. That's why the semitendinosus is the back-of-thigh muscle known for its long tendon and its job in bending the knee.
