In your arm
The above answer is incorrect. He/she is referring to the triceps brachii. The triceps femoris is a posterior thigh muscle in Anurans (frogs and toads); though I cannot say that it occurs in all species in the Order.
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
extends leg; straightens knee joint
The Quadriceps extend just like the triceps, which include the rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius. The Hamstrings flex just like the biceps, which include the biceps femoris, semitendinosus, and semimembranosus. Quads extend, Triceps extend Hamstrings flex, arm biceps (biceps brachii, brachialis) flex
The tricpes brachii muscle is one muscle. It is an extensor muscle, meaning that it opens, or extends the arm from the shoulder (as opposed to the bicpes, which is a flexor muscle, that closes the arm.)
There is no part of the body called the vastus femoris. The vasti muscles are a group of five muscles that are located on the anterior part of the femur. They function in the bending of the leg at the knee.
the real name is rectus femoris, the vastus muscles are the ones laterally, medially and intermedius, there is no vastus femoris. the Quadriceps Femoris are: rectus femoris, vastus lateralis, vastus medialis and vastus intermedius.
triceps
The term femoris refers to anything concerned with the thigh.
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.
There are 4 groups in the quadriceps femoris muscle.
