Sequence of nerve impulse

WebThe nervous system of our body detects certain stimuli and performs a response action before we become aware of the stimulus. Reflex action is one example of such responses. A reflex action is an involuntary response to a stimulus, mostly a pain stimulus, that takes place instantaneously.
