Webreflexes The term ‘reflex’ was first used to describe an automatic, almost immediate movement in response to a stimulus, involving a nerve circuit that traverses the spinal cord. It is now applied also to other types of automatic response to a stimulus, including those involving the brain. WebReflex action: Not all activities of animals are the results of judgement and deliberations. Certain actions occur without even the animal being aware of it, e.g. sudden withdrawal of hand or feet from hot, cold, sharp and pointed objects; sudden closure of eyelids in strong light, etc. Such actions are termed reflex actions.
