Match functional catagories: Agonist                                                     Muscle that opposes and reverses the action of another muscle. Synergist                                                  Muscle that stabilizes the origin of another muscle. Antagonist                                               Muscle that is primarily responsible for bringing about a particular movement. Fixator                                                                       Muscle that aids another by  promoting the same movement.
