What are muscles that work in opposing pairs called?

Answer 1

One is the agonist and the other is called the antagonist.

Agonist: muscle which is the main mover, it contracts and shortens

Antagonist: muscle that lengthens and controls

e.g. flexion at the elbow: the biceps are the agonist and the triceps are the antagonist.

Answer 2

they are called antagonistic, usually in pairs.
Antagonist muscles. The main muscle is the prime mover, and the antagonist muscle is the muscle that moves in opposition, and as a result of, the movement of the Prime Mover. E.g. Biceps and Triceps Flexing hand TOWARDS body. Bicep=Prime Mover=Contracts to produce movement Tricep=Antagonist Musce=Relaxes to allow movement. This works in opposite for an extension of the arm.

Answer 3

These muscles are known as antagonistic pairs of muscles, Most common example is biceps and triceps muscles which are responsible for contraction and relaxation of arm.

Answer 4

An opposing pair of skeletal muscles are usually called the prime mover and the antagonist.

Answer 5

opposing muscle groups produce smooth, controlled motions. they protect the joint from strong contraction.

Answer 6

A pair of muscles that work together.

Answer 7

Agonist
