Muscles of the posterior thigh and the hamstrings

This tutorial by Ron from Ken Hub covers the anatomy of the posterior thigh muscles, focusing on the biceps femoris, semimembranosus, and semitendinosus. It discusses their origins, insertions, innervations, and functions, emphasizing their role in hip extension and knee flexion. The tutorial also explains the pes anserinus, a conjoined tendon at the knee. The video concludes with resources for further learning.
