Expert Solution & Answer

Summary Introduction

To determine:

The type of muscle that assists an agonist either by causing a like movement or by providing the stability to the joint on which agonist acts upon is:

  1. Antagonist

  2. Prime mover

  3. Synergist

  4. Agonist

Answer to Problem 1MC

Correct answer:

(c) Synergist: The term “synergist” refers to the working together of two or more components. Similarly, the combined effect thus generated is referred to as the synergistic effect.

Explanation of Solution

Explanation for the correct answer:

An agonist is a muscle that is responsible for generating a specific movement. It might also be referred to as the prime mover, for example, the pectoralis muscle. Synergists help the agonist or the prime mover in completing its movement by aiding a small amount of force or avoiding the movements that are not necessary. Thus option (c) is considered as a correct answer.

Explanation for the incorrect answers:

Option (a) is given as antagonist. Antagonistic muscle is defined as the muscle that opposes the action of another muscle. Example: biceps and triceps. Thus this option is considered as an incorrect answer.

Option (b) is given as prime mover. Prime mover is defined as the muscle that is primarily responsible for the generation or control of a specific movement. Example: pectoralis major muscle is a prime mover of arm flexion. Thus this option is considered as an incorrect answer.

Option (d) is given as agonist. Agonist or Prime mover are the words used interchangeably for the muscle that is primarily responsible for producing a specific movement. Thus this option is considered as an incorrect answer.

Hence, option (a), (b) and (d) are considered as incorrect options.

Conclusion

Thus, it is concluded that synergist is a muscle that help the prime mover in completing its movement by aiding a small amount of force or avoiding the movements that are not necessary.
