A normal automatic response in a fight or flight situation or guage used by a neurologist when checking your natural reflex reactions during a neurological exam. Peace!

A reflex action or reflex is a biological control system linking stimulus to response and mediated by a reflex arc. Reflexes can be built-in or learned. It occurs very quickly before thinking. Before the message is sent to the brain, the spinal cord senses the sensory stimulus, and sends a signal (action potential) to an effector organ, (muscle) to create an immediate action to counter the stimulus. For example, a person stepping on a sharp object would initiate the reflex action through the creation of a stimulus, (pain) within specialized sense receptors located in the skin tissue of the foot. The resulting stimulus would be transmitted through afferent, or sensory neurons and processed at the lower end of the spinal cord, part of the central nervous system. This stimulus is processed by an interneuron to create an immediate response to pain by initiating a motor (muscular) response which is acted upon by muscles of the leg, retracting the foot away from the object. This activity would occur as the pain is arriving in the brain which would process a more cognitive evaluation of the situation

Reflex action.. the instant and typical reaction to an action that deems response. Normally talking about nerve-endings.
