The biceps femoris (/ ˈ b aɪ s ɛ p s ˈ f ɛ m ər ɪ s /) is a muscle of the thigh located to the posterior, or back. As its name implies, it consists of two heads; the long head is considered part of the hamstring muscle group, while the short head is sometimes excluded from this characterization, as it only causes knee flexion (but not hip extension) [1] and is activated by a separate ...
biceps femoris muscle, which consists of a short head and a long head. semitendinosus muscle; semimembranosus muscle; These muscles (or their tendons) apart from the short head of the biceps femoris, are commonly known as the hamstrings. The depression at the back of the knee, or kneepit is the popliteal fossa, colloquially called the ham. The ...
Immediately below its origin is the groove for the tendon of the popliteus. [citation needed]The greater part of its lateral surface is covered by the tendon of the biceps femoris; the tendon, however, divides at its insertion into two parts, which are separated by the ligament.
The lower border of the ligament was found to be directly continuous with the tendon of origin of the long head of the biceps femoris in approximately 50% of subjects. [3] biceps femoris could therefore act to stabilise the sacroiliac joint via the sacrotuberous ligament.
Green is the medial compartment (gracilis and adductor magnus), blue is the posterior (semimembrosus to biceps c. brevis) and red is the anterior (vastus lateralis to sartorius). The fascial compartments of thigh are the three fascial compartments that divide and contain the thigh muscles .

It runs over the long head of the biceps femoris to the back of the knee. [citation needed] It pierces the fascia lata posterior to the knee. It then accompanies the small saphenous vein to about the middle of the posterior leg (i.e. lower leg). [2] Its terminal branches communicate with the sural nerve. [citation needed]
The biceps femoris has two heads: The long head has its origin on the ischial tuberosity together with the semitendinosus and acts on two joints. The short head originates from the middle third of the linea aspera on the shaft of the femur and the lateral intermuscular septum of thigh , and acts on only one joint.
