Question

Antagonistic muscles are responsible for opposing movements.

• A. True
• B. False

Answer 1

The correct option is A

True

A structure which has been moved by a muscle cannot return to its original position without the action of another muscle. Such muscles causing opposing movements are called antagonistic muscles. For example, the biceps muscle of the upper arm bends the lower arm over the upper arm. Straightening of the lower arm is brought about by the triceps muscle.
