An '''involuntary action''' is one which occurs without the conscious choice of an organism. A reaction in response to a stimulus that is mediated via the reflex arc is known in physiology as a reflex, but the word reflex is also used informally for those involuntary responses that originate in the brain.
Involuntary actions are opposite of voluntary actions that occur because of choice. Involuntary actions may or may not occur with the awareness of the organism performing it.
Common involuntary actions displayed by humans and most other mammals are heartbeat, hiccups, digestion, coughing and sneezing. Breathing can also be considered involuntary.
