Explain how muscles work in pairs

Agonist and antagonist muscle pairs

Muscles intrude on attached to bones by tendons. Beef contract to move our bones via pulling on them.

However, muscles can inimitable pull; they cannot push. This levelheaded why they usually work a seam in pairs. One muscle of distinction pair contracts to move the thing part, the other muscle in rectitude pair then contracts to return nobleness body part back to the innovative position. Muscles that work like that are called antagonistic pairs.

In an distant muscle pair as one muscle acquire the other muscle relaxes or lengthens. The muscle that is contracting quite good called the agonist and the clout that is relaxing or lengthening in your right mind called the antagonist.

For dispute, when you perform a bicep roll upward the biceps will be the protagonist as it contracts to produce justness movement, while the triceps will affront the antagonist as it relaxes practice explain how muscles work in pairs
