The Rectus femoris muscle is one of the four quadriceps muscles of the human body. (The others are the vastus medialis, the vastus intermedius, and the vastus lateralis. All four combine to form the quadriceps tendon, which inserts into the patella and continues as the patellar ligament. ) The Rectus femoris is situated in the middle of the front of the thigh; it is fusiform in shape, and its superficial fibers are arranged in a bipenniform manner, the deep fibers running straight down to the deep aponeurosis.
