Structure And Function Of the Living Organisms: How Impulse Travels in Reflex Movement

Reflex movements occur without conscious awareness and are faster than voluntary actions. An example is the quick withdrawal of a hand from a hot object to prevent injury. Reflex actions are processed in the spinal cord and brainstem, bypassing the brain for faster response. The reflex arc involves a stimulus being detected by receptors, sending an impulse through sensory nerves to the spinal cord, and then through motor nerves to muscles, resulting in a quick reaction.
