Question

7. How do muscles work in antagonistic pairs?
The muscles alternate, producing wavelike contractions,
When one muscle pulls, the other muscle relaxes,
Each muscle is attached to a different ligament,
Both muscles always contract at the same time,

Answer 1

Answer:

As one muscle contracts, the other relaxes.

An example of an antagonistic pair is the biceps and triceps; to contract, the triceps relaxes while the biceps contracts to lift the arm.
