What is the antagonistic muscles?

Antagonist muscle is one that works in opposition to movement initiated by the agonist muscle. The antagonist muscle in the muscle set brings a limb or other anatomical part back to the original position of rest. These muscle sets are referred to as antagonistic couples that are needed by the body, because muscles can only evolve the power that pulls the ligaments and bones; He needs the opposite muscles in the pair to return to his original position. The muscle responsible for relocating part of the body from its position is shortened or the antagonistic muscle reacts by stretching, which allows second movement. One example of this pairing includes biceps brachii and triceps brachii. When biceps brachii happens, Triceps Brachii relaxes, allowing him to reach back to his resting position; The opposite occurs when Brachii closes. Agonist/antagonist pairing can also be identified as a flexor/extensor pairing. Flexor moves to open the joint while the extensor makes aboutThen and reduces the joint angle. The antagonist's muscle is particularly important when a person expands or holds limb contracts against gravity and seeks to maintain balance during the exhibition.

The movement of agonistic/antagonistic muscle groups is coordinated by the central and peripheral nervous system. The motor cortex inside the brain sends a message and the peripheral nervous system into an agonistic muscle. The motor cortex in the right hemisphere controls movements on the left side of the body and the movement on the left controls the right. This signal begins with a complex movement, which eventually leads to antagonistic muscles that bring part of the body back to the resting place. The antagonistic muscle helps the body to maintain a state of relaxation.

All muscles contain receptors or muscle spindles that receive specific reports from the motor cortex. Muscle spindles placed in an antagonistic muscle receive signals that inform them about the muscle that KTErý is in a state of contraction. It begins to stretch in response to this information. Sometimes muscle signaling can work the opposite; The agonist muscle receives a message that the other muscle is in the state of the section and then downloads or shortens to reverse the section. Most muscle systems in the body work on the basis of this basic principle.
