Where does the semitendinosus muscle insert?

The semitendinosus muscle inserts on the medial surface of the proximal shaft of the tibia, which is the correct answer. This muscle is one of the hamstring group located at the back of the thigh, and it plays a significant role in knee flexion and hip extension.

The insertion on the medial surface of the proximal shaft of the tibia occurs near the location known as the pes anserinus, where several muscles converge. This anatomical placement allows the semitendinosus to function effectively in its roles, contributing to leg movement and stability. Understanding this insertion point is vital for sports massage practitioners as it can help address potential issues related to muscle tension and flexibility in athletes who engage in activities involving running or kicking.
