MEDICAL PHYSIOLOGY

Detailed explanation-1: -The muscle primarily responsible for a movement is called the prime mover, and muscles that assist in this action are called synergists. A synergist that makes the insertion site more stable is called a fixator. Meanwhile, a muscle with the opposite action of the prime mover is called an antagonist.

Detailed explanation-2: -Synergists are muscles that assist the prime mover in its role.

Detailed explanation-3: -Synergist muscles act around a moveable joint to produce motion similar to or in concert with agonist muscles. They often act to reduce excessive force generated by the agonist muscle and are referred to as neutralizers.

Detailed explanation-4: -Synergists. Synergists help prime movers by producing the same movement or by reducing undesirable movements. Fixators. Fixators are specialized synergists; they hold a bone still or stabilize the origin of a prime mover so all tension can be used to move the insertion bone.

Detailed explanation-5: -Synergist muscles also called fixators, act around a joint to help the action of an agonist muscle.
