With the Paarhufern the muscle with the Musculus grew together gluteus superficialis to the Musculus gluteobiceps. With the four-legged mammals a Nebensehne of the Biceps irradiates femoris (heel leg chord, Tendo accessorius) also into the Achilles' tendon.

Function

The long head affects both on the hip joint (aspect ratio and external rotation) and the knee joint, the short head only on the knee joint. In the knee joint the effect of the two portions is identical: Both bend the knee joint and can with bent knee joint the Unterschenkel outward turn.

With the animals the effect of the Musculus is still more complex biceps femoris. However beside the aspect ratio and Abduktion of the hip joint he works with the put on leg ("“supporting leg"”) as Kniestrecker, with the raised ("“slope leg"”) as Kniebeuger. By its heel leg chord the muscle works also as Strecker of the jump joint.

Sometimes the Caput breve is missing. The external rotation in the bent knee joint must be implemented then by the Caput longum alone.
