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'.
In trunk flexion, the agonist is the rectus abdominis muscle, which contracts to flex the trunk forward. The antagonist is the erector spinae muscles, which lengthen to allow the trunk to flex.

The rectus femoris THe regular Muscle Action is hip flexion with knee extension, as in kicking a ball or doing a straight leg raise The reverse muscle action is still hip flexion with knee extension, but as in doing sit-ups while lying supine with knes straight ahead
prime mover (agonist)Not sure what you're asking here, but the biceps brachii is the prime mover facilitating flexion at the elbow joint.
