PATHOLOGY

Detailed explanation-1: -A reflex is a rapid, unlearned, involuntary (automatic) response to a stimulus (change in the environment). Reflexes are responses that protect the body from potentially harmful events that require immediate action. They involve relatively few neurons (nerve cells) so that they can occur rapidly.

Detailed explanation-2: -Reflexes are unconscious responses, which means they are automatic and do not require the brain to create the action.

Detailed explanation-3: -Autonomic reflexes are unconscious motor reflexes relayed from the organs and glands to the CNS through visceral afferent signaling.

Detailed explanation-4: -Within the reflex arc, specific receptors trigger a response that occurs without the need for conscious thought. The receptor works together with the nervous system, which carries the signal to an effector. The effector carries out the response to the stimulus.
