Biceps Femoris – Anatomy, Purpose and Injury Prevention

The biceps femoris muscle is a significant muscle in the body. It is part of the group that makes up the hamstring. The other muscles of the hamstring are:

  • Semitendinosus muscle
  • Semimembranosus muscle

The hamstring muscles are popular amongst athletes because of the role they play in hip extension when running. It is also one of the muscles that are easily injured by any athlete that runs full speed due to poor running mechanics and a lack of strength.

It is important to note and not confuse the biceps femoris which is a muscle in the posterior part of the thigh with the biceps brachii which is a muscle in the upper arm of the body.

In this article, we will be discussing the anatomy, functions and how to prevent and treat injuries that affect the biceps femoris muscle.

Biceps Femoris: Anatomy

Biceps Femoris

The biceps femoris is a muscle with two heads or branches that are located in the posterior part of the thigh. It has a long head and a short head.

It is the long head that forms part of the hamstring muscles. The short head extends up the thigh and joins with a muscle known as the gluteus maximus or glutes for short.

The sciatic nerve provides the nerve supply to both heads of the muscle. Blood is supplied to both heads of the muscle through the profundal femoris artery, inferior gluteal artery, and the popliteal artery.

Biceps Femoris: Function

The biceps femoris is a criticalย muscle for knee flexion and hip extension joint. This is why an injury to this muscle is always harmful to an athlete.

The important functions of the biceps femoris muscle to note are:

  • It gives posterior stability to the pelvic region of the body.
  • The two heads of the biceps femoris muscle provide stability known as rotatory stability and prevent dislocation between the tibia and the femur.
  • It helps the leg to perform outward rotation movements.
  • Flexion of the knee (Flexion is the action of bending a limb or a joint in the body)
