In medicine, a reflex is an involuntary reaction of the body to a stimulus.A 1913 edition of Webster's Dictionary defines reflex as meaning
and a reflex action as
- "Of, pertaining to, or produced by, stimulus or excitation without the necessary intervention of consciousness."
Ivan Pavlov unintentionally launched the study of conditioning by establishing a way of producing what he called "conditional reflexes", i.e. reflexes that would only be seen conditional on previous experiences of the subject.
- "any action performed involuntarily in consequence of an impulse or impression transmitted along afferent nerves to a nerve center, from which it is reflected to an efferent nerve, and so calls into action certain muscles, organs, or cells."
Reflex actions seen in humans include:
Processes such as breathing. digestion and the maintenance of the heartbeat can also be regarded as reflex actions, according to some definitions of the term.
