hip flexion and hip extention
The prim mover for hip flexion is the Rectus femoris. This is a quadricep muscle that crosses the hip joint.
The flexor carpi radialis is the agonist muscle in wrist flexion. This muscle, know as a wrist flexor, is located in the forearm.
The agonist muscle for wrist flexion is the flexor carpi radialis, while the antagonist muscle is the extensor carpi radialis longus. These muscles work in opposition to produce movement at the wrist joint.
Technically speaking it's the abs. The agonist muscle in a situp is actually the hip flexors.
the tensia fascia muscle does abduction, medial rotation and flexion of the hip joint
Function of the sartorius is flexion of the hip and knee joints. It is also called as 'Tailor's muscle'.
Rectus abdominis is the prime agonist and the superior and inferior oblique muscles are synergists. Erector spinae is an antagonist including a number of other muscles of the back.
The agonist in the hamstring muscles, primarily when flexing the knee, is the hamstring group itself, which includes the biceps femoris, semitendinosus, and semimembranosus. These muscles contract to produce the movement, while the quadriceps act as the antagonist, opposing the action of knee flexion. The hamstrings also assist in hip extension when the hip is flexed.
The muscle that produces a movement is called the "agonist," while the muscle that produces the opposite movement is known as the "antagonist." For example, during elbow flexion, the biceps brachii acts as the agonist, while the triceps brachii serves as the antagonist. This relationship allows for coordinated movement and control in the body.
