Nerve Actions

Nerve Actions

There are three types of nerve actionsvoluntary, involuntary, and reflex. Voluntary nerve action is under the control or command of the brain, e.g., talking, writing, Involuntary nerve action operates without the command of the brain as per the requirement of sensation generated in internal organs, e.g., peristalsis. Reflex action is a nerve-mediated automatic, mechanical, and immediate response to a stimulus for protection and functional efficiency, e.g., closing of eyes when strong light is flashed over them, pulling of hand from a hot surface before brain feeling the pain.
