APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -The knee flexors include the set of hamstrings, gracilis, sartorius, gastrocnemius, plantaris, and popliteus . Most of these knee flexors also internally or externally rotate the knee. The hamstring muscles are the primary knee flexors. They play a key role in everyday movements, eg running, walking.

Detailed explanation-2: -The quadriceps muscles and hamstring muscles provide most of the power and control for the knee joint. The quadriceps muscles. This is a group of four muscles: (vastus lateralis, vastus intermedius, vastus medialis, and rectus femoris) located on the front of the thigh.

Detailed explanation-3: -The quadriceps femoris muscle group (rectus femoris, vastus lateralis, vastus medius, and vastus intermedius) crosses the knee via the patella and acts to extend the leg. The hamstring group muscles (semitendinosus, semimembranosus, and biceps femoris) flex the knee and extend the hip.
