The long head of the bicep femoris, extends the hip, and it also, along with the short head of the bicep femoris, flexes and externally(laterally) rotates the knee.
Biceps femoris performs knee flexion.
The primary antagonist to the rectus femoris is the biceps femoris, a muscle of the hamstring group. When the rectus femoris contracts to flex the hip and extend the knee, the biceps femoris acts to flex the knee and extend the hip, helping to create balanced movement.
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 part of the hamstring. The other parts of the hamstring are the semitendonous and the semimembranous.
The biceps femoris is lateral to the semimembranosus. The semimembranosus is closer to the midline of the body.
The biceps femoris is one of the hamstring muscles located at the back of the thigh, and its primary function is to flex the knee and extend the hip. During knee extension, the quadriceps muscles contract to straighten the leg, while the biceps femoris must relax to allow this movement to occur. Hence, it acts as an antagonist to the quadriceps during knee extension, opposing their action and facilitating smooth movement.
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
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.
Biceps Femoris, Semimembranosus, and Semitendinosus
