Semitendinosus muscle (3D)

The video tutorial explores the semitendinosus muscle, a posterior thigh muscle part of the hamstrings. It covers the muscle's location, nerve supply via the tibial nerve, and its origin from the ischial tuberosity. The semitendinosus is involved in extending the thigh at the hip joint, flexing the leg at the knee joint, and facilitating internal rotation when the knee is flexed. The tutorial concludes with a recap of these functions.

Explain the significance of the term 'Pez anserinus' in relation to the semitendinosus muscle.

How does the semitendinosus muscle contribute to internal rotation at the knee joint?
