biceps brachii
An antagonist muscle reverses the action of a prime mover. When the prime mover contracts to produce a movement, the antagonist muscle relaxes to allow that movement to occur in the opposite direction. This coordination between prime movers and antagonists is essential for controlled and coordinated movement.
The antagonist muscle in the flexion of the knee is the quadriceps muscle group. When the knee is being flexed, the quadriceps relax to allow the hamstrings to contract and bring about the flexion movement.
The antagonists to the pectorals are the muscles in the upper back, specifically the rhomboids and trapezius. These muscles work in opposition to the pectorals to allow for controlled movement and to prevent injury.
Muscles that cause primary movement are called agonist muscles. These muscles contract to produce the desired movement, while antagonists relax to allow the action to occur. For example, during a bicep curl, the biceps act as the agonist, facilitating the lifting of the weight.
Muscle tissues allow the human body to move its limbs and to move parts of the organs. Muscle tissues contract or expand in order to provide the required motion.
Muscles allow the skeleton to move.
