Synergists help steady movements and fixators help stablize the prime movers origin.
Agonist muscles are the primary muscles responsible for producing movement. However, synergist muscles are helper muscles that assist the agonist in executing a particular movement. Synergists help stabilize the movement and control the direction in which the force is exerted.
prime movers : muscle that initiate a particular movement synergism : muscles that have the same action of the prime mover antagonist : muscles that come into play to oppose a certain movement
The primary movement is called the Prime mover or Agonist
The two functional characteristics used to classify muscles into classes are agonist and antagonist. Agonist muscles are responsible for causing movement, while antagonist muscles work in opposition to the agonist to help control the movement.
in the arm: bicep contracts (agonist) triceps relax (antagonist) in the leg: hamstrings contract (agonist) quadriceps relaxes (antagonist) remember the agonist is the muscle "agonising" to do the work - like pulling the joint.
Deltoid
The agonist muscle
The agonist muscle
The agonist being the biceps brachii group. The two synergist muscles that assist the biceps brachiiare the brachialis and to a lesser extent the brachioradialis.
A muscle that assists the primary mover or Agonist
Agonist & AntagonistsAgonist is the muscle responsible for the primary movement ( muscle that contracts)Antagonist is the opposite muscle that must relax to allow the agonist to move a joint.
