Question

One of the following is a set of antagonistic muscles. Select the wrong set.

• A. Fexor, Relaxor
• B. Abductor, Adductor
• C. Pronator, Supinator
• D. Elevator, Depressor

Answer 1

The correct option is A Fexor, Relaxor

In antagonistic muscle pairs, one muscle contracts and another relaxes. The muscle that contracts is called agonist and the other one which relaxes is called antagonist. E.g. Flexor and Extensor, Adductor and Abductor, Pronator and Supinator, Elevator and Depressor are some examples of important antagonist muscle pairs.
So, "Fexor and Relaxor" are not the correct set of antagonistic muscles.

Thus, the correct answer is (A).
