Reflexes are involuntary actions, whereby a stimulus - touching a boiling plate, for example - triggers an almost instantaneous response from our muscles. In this demonstrated case, the response would be to let go of the plate and retract your hand quickly.
They are innate, so we are born with the intuition necessary to respond fast to a stimulus. The reflex action does not involve the brain. It bypasses the brain and uses just the sensory, relay and motor neurones to ensure that we come to as little harm as possible.
Another reflex would be blinking when someone aims a punch at you. Because the response (blinking) does not need the brain's intervention, time is saved which could end up being the difference between losing, or saving, your sight.
