WebReflex arc: definition and characteristics. The reflex arc is a neurophysiological mechanism of the nervous system that is activated in response to an external stimulus, as when we give ourselves a strong blow or bring a source of heat closer to our body. The reflex movements are automatic and involuntary, since, unlike what happens with most ... WebA neural reflex arc is characterized by peripheral afferent sensory input that is transmitted to the central nervous system and processed; the resultant action is carried by efferent motor neurons to the periphery. Thus, at least two synaptic connections are …
