Physiology and Pathophysiology of Reciprocal Inhibition in the Human Forearm
Active inhibition of antagonist muscles during voluntary movement is accomplished largely from two sources: by central descending commands from the brain and by peripheral input from agonist muscle spindle Ia afferents. Work on animals has demonstrated that both the central and peripheral sources of inhibition act through the same system of spinal Ia inhibitory interneurones (see ).
