actin
thin stringlike myofilament that acts along with myosin to produce muscular contraction

reciprocal inhibition
when an agonist receives a signal to contract its functional antagonists also receives an inhibitory signal allowing it to lengthen
altered reciprocal inhibition
occurs when an overactive agonist muscle decreases the neural drive to its functional antagonist
