What are the role of agonist, antagonist and synergistic muscles in accomplishing joint motion?
AGONIST-Prime mover which can cause a specifif joint motion.For eg., the biceps brachii contracts to cause elbow flexion ANTAGONIST -Any muscle that can produce a motion oppoosite to the specific agonist motion.For eg., triceps brachii is an antagonist to elbow flexion. SYNERGIST -These muscles normally contract to remove unwanted actions of agonists or to stabilize other (usually more proximal) joints. For eg., during elbow flexion by the biceps brachii, the forearm pronators contract to remove the undesirable supination which the biceps would produce.
