Detailed explanation-1: -An involuntary response to a stimulus is known as reflex action. Reflex actions occur when our body needs to react to immediate danger such as accidentally tough a hot object. A reflex arc is a neural pathway that controls a reflex action.
Detailed explanation-2: -A reflex is an automatic, involuntary response to an incoming stimulus. Sensory (afferent) neurons transmit information from the perimeter of the body to the central nervous system.
Detailed explanation-3: -A reflex is an involuntary (say: in-VAHL-un-ter-ee), or automatic, action that your body does in response to something-without you even having to think about it.
Detailed explanation-4: -Some functions are involuntarily performed, such as breathing, digestion, heart beating, eye reflexes, etc., but some involuntary actions have voluntary control to a certain extent – examples are breathing, salivation, deglutition (swallowing), defecation, micturition (urination) and others.
