What following muscles acts on the knee joint?
The muscles that act on the knee joint include the quadriceps femoris, which extends the knee, and the hamstrings, which flex the knee. Additionally, the gastrocnemius, which also contributes to knee flexion, and the popliteus, which aids in unlocking the knee, play significant roles. The stabilizing muscles around the knee, such as the iliotibial band and some of the adductors, also contribute to its function and stability.
What muscles act to flex the leg?
