The type of muscle mover that is most responsible for a specific movement within the musculoskeletal system is which of the following?
a. synergist
b. stabilizer
c. agonist
d. antagonist
Answer: c. agonist
An agonist muscle (or prime mover) is the most responsible for producing a specific movement. The synergist, stabilizer, and antagonist muscles for that movement will assist the agonist in movement, help provide stability, and produce opposite actions to those of the agonist.
