NAMING MUSCLES Flashcards
Proximal or superior attachment
-closer to the origin
-proximal: appendicular muscles
-superior: axial muscles, usually more moveable
Distal or inferior attachment
-distal: appendicular muscles (more moveable)
-inferior: axial muscles
Prime mover/Agonist
-muscle primarily responsible for the movement
Antagonist
-stretches and yields to the effects against the agonist
Synergists
-muscles used to prevent unwanted movements at the intermediate joints
-or aid in the movement of the agonist
