BICEPS FEMORIS

The biceps femoris (biceps flexor cruris) muscle is included with the hamstring muscle group. The biceps femoris is a large muscle comprised of two heads (two points of attachment to the bone), the long head (caput longum) and the short head (caput breve). The long head originates from the tuberosity of the ischium near the semitendinosus muscle and the short head originates from the linea aspera between the adductor magnus and the vastus lateralis muscles. The two muscles converge to a single tendon and insert in the fibula. This common tendon is located on the outer back corner of the knee and forms the outer hamstring. The long head of the biceps femoris is innervated by the tibial nerve and the short head is innervated by the peroneal nerves. This muscle is supplied by a deep branch of the femoral artery, the profunda femoris. Both heads of the muscle flex the lower leg at the knee joint and rotate the tibia outward. The long head also assists with the extension and outward rotation of the thigh at the hip joint, making it a two-joint muscle, while the short head is a single-joint muscle.

BICEPS FEMORIS TENDON

The biceps femoris tendon connects the patella to the femur. It is responsible for extension of the knee joint and is given its name because it features two muscular heads, one at the femur and one at the patella.
