What are the three parts of the hamstring group?
Biceps femoris, semitendinosus, semimembranosus.
True or False: The vastus lateralis is part of the quadriceps group.
True.
What is the origin of the biceps femoris?
Ischial tuberosity and linea aspera of the femur.
What is the main action of the semimembranosus?
Flexion of the knee and extension of the hip.

What is the role of the vastus intermedius?
Knee extension.
True or False: The adductor magnus is located in the posterior thigh.
False.
Which muscle group is primarily responsible for knee flexion?
