quadriceps femoris

A

muscles crossing the hip and knee joints, movements of the thigh and leg<br></br>anterior and medial muscles<br></br>muscles of the anterior compartment of thigh<br></br>hos four separate heads (quadriceps=four heads) that form the flest of front and sides of thigh. these heads (rectus femoris, and lateral, medial, and intermediate vastus muscles) have a common insertion tendon, the quadriceps tendon, which inserts into the patella and then via the patellar ligament into tebial tuberosity. the quadriceps is a powerful leg extensor used in climbing, jumping, running, and rising from seated position. the group is innervated by femoral nerve. the tone of quadriceps is important in strengthening the knee joint
