Biceps femoris performs knee flexion.
There is no such muscle. Their is a biceps femoris and it is in the thigh as one of the three hamstring muscles. They are: biceps femoris, semitendinosus, and semimembranosus. yes there is this guy doesnt know what he is talking about. it is in a frog
The biceps femoris are the large muscles in the back of the upper legs, where they connect to the hamstring tendons.(Similarly, the biceps or biceps brachii, are muscles of the upper arm.)
biceps femoris
The biceps femoris is lateral to the semimembranosus. The semimembranosus is closer to the midline of the body.
The biceps femoris is part of the hamstring. The other parts of the hamstring are the semitendonous and the semimembranous.
biceps femoris, semitendinosus and semimembranosus
I believe it is the Biceps Femoris muscle.
“femoris” refers to the femur bone on the thigh, “biceps” to the two origins of the muscle.
- Popliteus - Semimembranosus - Semitendinosus

Biceps Femoris, Semimembranosus, and Semitendinosus
The name of the biceps femoris muscle implies two aspects. Biceps means two headed (bi- means two, ceph/s means head), and femoris referrs to the bone of the upper leg. So just by its name you know that the biceps femoris is a muscle in the upper leg that has two heads (attachment points).
