The thigh a.k.a. The quadriceps femoris consists of four individual muscles. The three vastus muscles and the rectus femoris. It forms the main bulk of the anterior thigh, and is one of the most powerful muscles in the body. The four muscles collectively insert onto the patella via the quadriceps tendon. The patella, in turn, is attached to the tibial tuberosity by the patella ligament.
