Description. Biceps femoris is a muscle of the posterior compartment of the thigh, and lies in the posterolateral aspect. It arises proximally by two 'heads', termed the 'long head' (superficial) and the 'short head' (deep). It is part of the hamstrings.
What is the biceps femoris function?
Function: The primary function is flexion of the knee. With the knee semi-flexed, the muscle functions as a lateral rotator of the lower leg on the knee. With the hip extended, the biceps femoris is a lateral rotator of the thigh.
Are hamstrings and biceps femoris the same?
Structure and Function The semitendinosus, semimembranosus, and biceps femoris muscles comprise the hamstring muscle group. Beginning at the pelvis and running posteriorly along the length of the femur, the majority of muscles within the hamstring complex cross both the femoroacetabular and tibiofemoral joints.
Where are your bicep femoris?
The biceps femoris is one of the hamstring muscles at the back of the thigh. It originates in two places: the ischium (lower, rear portion of the pelvis, or hipbone) and the back of the femur (thighbone).
Why is it called biceps femoris?
The biceps femoris muscle of the leg derives its name from having two heads of origin, long and short. The long head arises from the medial facet on the ischial tuberosity in continuity with the tendon of origin of semitendinosus.
How do I strengthen my biceps femoris?
Workouts For HamstringsExercise #1: Straight-Legged Deficit Deadlifts.Exercise #2: Lying Leg Curls.Exercise #3: Good Mornings.Exercise #4: Standing Leg Curl.Exercise #5: Weighted Hip Thrusts Dropsetted Into Bodyweight Hip Thrusts.
What causes tight biceps femoris?
NERVE ENTRAPMENT & HAMSTRING TIGHTNESS: One of the major causes of hamstring symptoms stems from nerve entrapment. The bicep femoris muscle runs overtop of the sciatic nerve, and sometimes the sciatic nerve can get trapped under it.
How do you test biceps femoris?
PalpationPosition the client in prone lying with the knee in slight flexion.Starting distally locate the lateral proximal border of the popliteal fossa to locate the insertion of the tendon.Palpate the hamstrings laterally to locate the biceps femoris.More items...
What does biceps femoris pain feel like?
The patients suffering from the biceps femoris tendon rupture may complain of sharp pain at the back of the knee and posterior thigh following hyperextension of the affected knee. They may feel a pop on the affected knee during knee extension. In proximal avulsion cases, the patient can complain of pain on sitting.
What does femoris mean in anatomy?
femura Latin word meaning "femur" (= the long bone in the upper part of the leg), used in medical names and descriptions.
Does the biceps femoris extend the hip?
In general, the biceps femoris muscle acts on both the knee and hip joints. Although, due to its attachments, the short head of this muscle acts only on the knee joint while the long head acts on both. When acting on the hip joint, biceps femoris produces the movement of hip extension.
What is the difference between the biceps femoris and the biceps brachii?
Biceps muscles are any group of muscles that have two points of origin. There are two types of biceps in the human body, the biceps brachii on the front side of the upper arm and the biceps femoris, which pulls the thigh near the trunk.
What is the proper name for the hamstring muscle?
The muscles in the posterior compartment of the thigh are collectively known as the hamstrings. They consist of the biceps femoris, semitendinosus and semimembranosus, which form prominent tendons medially and laterally at the back of the knee. As group, these muscles act to extend at the hip, and flex at the knee.

The biceps femoris is a long muscle in the posterior compartment of the thigh responsible for movement at both the hip and knee joints. Along with the semitendinosus and semimembranosus, the biceps femoris makes up the hamstrings muscle. The muscles of the hamstring border the popliteal fossa, which is a triangular space behind the knee.

Biceps Femoris is one of the three hamstring muscles found on the back of the thigh. Its name means: Biceps: 2 headed muscle; Femoris: at the femur (thigh bone) The two heads of biceps femoris originate quite far apart from each other - he "long head" arises from the pelvis, and the "short head" arises from the femur.

The biceps femoris is a two-part spindle-shaped muscle. It has two heads: the long head and the short head. The two heads have different sites of origin and are innervated by different nerves, but they join together distally, inserting at the same location. The functions of the biceps femoris are in controlling knee and hip joint movements.
