All muscles that are agonists or synergists in knee extention, are antagonists in knee flexion.
Quadriceps group:
-Rectus femoris
-Vastus medialis
-Vastus lateralis
-Vastus intermedius
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.
Bicep Femoris
The bicep
The antagonist is your mom
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
The flexor carpi radialis is the agonist muscle in wrist flexion. This muscle, know as a wrist flexor, is located in the forearm.
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'.

Rectus femoris+ anterior thigh; quadriceps+ extension of leg at knee Vastus lateralis+ lateral anterior thigh; quadriceps+ extension of leg at knee Vastus Medialis+ medial anterior thigh; quadriceps+ extension of leg at knee Vastus intermedius+ deep anterior thigh; quadriceps+ extension of leg at knee Sartorius (*) parallel strap-like muscle that crosses thigh flexion of knee forward Biceps femoris* posterior thigh; hamstring* flexion of leg at knee Semitendinosus* posterior thigh; hamstring* flexion of leg at knee Semimembranosus* posterior thigh; hamstring* flexion of leg at knee

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
knee flexion and hip extension.Biceps femoris also: knee external rotation and hip external rotation.Semi tendinosus and Semi membranosus also: knee internal rotation and hip internal rotation.hamstrings eccentric contraction causes knee extension and hip flexion, whilst the antagonist muscles are passive.
