The semimembranosus and semitendinosus muscles attach on what side of the knee?

  1. Lateral

  2. Anterior

  3. Medial

  4. Posterior

The correct answer is: Medial

The semimembranosus and semitendinosus muscles are part of the hamstring group, which is located at the back of the thigh. These muscles play a crucial role in knee flexion and hip extension. The key aspect here is their attachment points. Both semimembranosus and semitendinosus attach to the medial aspect of the knee, which is significant for their function. Their medial position allows them to contribute to stabilizing the knee during various activities like running and jumping. Furthermore, the semimembranosus provides support and stability to the posterior and medial aspects of the knee joint, while the semitendinosus helps with the rotational movement at the knee. Recognizing the importance of this medial attachment is essential for understanding the biomechanics of the knee and how different muscles interact during movement.
