anon272083. Post 5. A synergist muscle joins in and assists the prime mover; it is not a stabilizer! A fixator helps maintaining a stable position. The antagonist muscle (in relation to the prime mover) relaxes, as muscles tend to work in pairs-one side contracts as the opposite side relaxes.lchemy. Post 3. @ Fiorite-Think of the terms synergist and agonist as a descriptor that describes the purpose of the muscle it is referred to. A synergist muscle can be the same as an agonist,or it can work with an agonist to perform a similar function. A synergist muscle prevents a muscle from oversextnding.
