Vastus medialis – anterior, medial surface of the femur Vastus intermedius – anterior, middle surface of the femur Insertion - - four muscles have a common tendon of insertion into the patella Actions - - extension at the knee, (great extensor of the leg) Hamstring Muscle Group Origin – all originate from the tuberosity on the ischium (3 muscles) Insertion – semitendinosus – upper part of the medial surface of the tibia - semimembranosus – posterior medial aspect near the top of the tibia - biceps femoris – lateral aspect of the tibia near the top and the head of the fibula Actions – flexion at the knee joint, extension at the hip joint Ankle Joint Bones Tibia Talus Calcaneus Movements Dorsiflexion – raising the foot towards the anterior surface of the leg Plantar Flexion – movement of the sole of the foot downwards, pointing the toes downward. Muscles Gastrocnemius Muscle Origin – posterior femoral condyles (bilaterally) Insertion – via the Achilles tendon to the posterior surface of the calcaneus
