All muscles that are agonists or synergists in knee extention, are antagonists in knee flexion.
The prime mover for knee flexion is the hamstring muscle group, including the biceps femoris, semitendinosus, and semimembranosus. These muscles originate from the ischial tuberosity in the pelvis and insert on the tibia and fibula, allowing them to flex the knee joint when contracting. Strengthening these muscles through exercises like hamstring curls can improve knee flexion strength and function.
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.
I came to this website to know the answers of my questions not answering the question
Prime mover is the bicep and the antagonist is the tricep.
Yes, and knee extension would be when the knee is straight.
The antagonist is your mom
The flexor carpi radialis is the agonist muscle in wrist flexion. This muscle, know as a wrist flexor, is located in the forearm.
The prime mover for knee flexion is biceps femoris, semimembranosus, and semitendinosus. The prime mover for knee extension is the Quadriceps â?? vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris
Tiil adidas is the prime mover of ankle plantar flexion.
Tibialis Posterior
rectus femoris
Function of the sartorius is flexion of the hip and knee joints. It is also called as 'Tailor's muscle'.

If a prime mover produces flexion, its antagonist will be the muscle responsible for producing extension at the same joint. They work in opposition to each other to create movement and stabilize the joint.

Sternocleidomastoid and the Scalenes are Synergists, which mean that they work together to provide the same movements (flexion, rotation and lateral flexion of the head and neck)An Antagonist is a muscle that does the opposite movements. In this case, Antagonists of the Scalenes would be your posterior neck muscles, such as:Upper TrapeziusSplenius CapitusSplenius CervicisSemispinalis Capitis, etc
