stimulus-response apparatus

a receptor region responding directly to a stimulus, e.g. sound, touch, smell, vision, an afferent neuron which conveys the stimulus towards the central nervous system, a synapse where the afferent path meets the efferent path, an efferent neuron conveying stimuli from the CNS, and an effector (a muscle, gland or neurosecretory cell).
