3. Knee & Leg Muscle AnatomyWhen looking at knee and leg muscle anatomy, the main knee muscles controlling the leg are the: Quadriceps: four muscles on the front of the thigh which straighten the knee - rectus femoris, vastus medialis, vastus lateralis and vastus intermedius Hamstrings: ...

Vastus Medialis Muscle Toggle Anatomy System Knee Joint (Deep Anterior View) × +− Click to View Larger Image The muscles of the knee include the quadriceps, hamstrings, and the muscles of the calf. These muscles work in groups to flex, extend and stabilize the knee joint. These motions...
The pouch of synovial membrane between the Quadriceps and front of the femur is supported, during the movements of the knee, by a small muscle, the Articularis genu, which is inserted into it. On either side of the patella, the synovial membrane extends beneath the aponeuroses of the ...
The largest bursae in the knee joint is thesuprapatellarbursa, located above the patella between the femur and thequadriceps femorismuscle. The function of this bursa is to allow the quadriceps tendon to move freely over the femur. This is acommunicatingbursa, meaning it is attached to the syn...
SeeKnee Anatomy The stretches described below can be done once or twice a day. When doing the stretches, it is important to maintain the right form to avoid straining joints. Use modifications if necessary. With all the stretches, as the person feels the muscle loosening up they can work ...
Patella - A sesamoid bone that enhances leverage for the quadriceps muscle Cartilage: Articular cartilage - It covers the surfaces of the femur, tibia, and patella, reducing friction and absorbing shock. Menisci - Medial and lateral menisci are fibrocartilaginous structures that stabilize the joint ...
