Detailed explanation-1: -You don’t have to think about it because the response is a reflex that does not involve the brain. 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.
Detailed explanation-2: -So, the correct answer is ‘Brain’.
Detailed explanation-3: -Autonomic reflexes are not subject to conscious control, are mediated by the autonomic division of the nervous system, and usually involve the activation of smooth muscle, cardiac muscle, and glands. Somatic reflexes involve stimulation of skeletal muscles by the somatic division of the nervous system.
Detailed explanation-4: -Reflexes are unconscious responses, which means they are automatic and do not require the brain to create the action. There are many different types of reflexes, but the most basic is called a simple reflex.
Detailed explanation-5: -A reflex action is an automatic (involuntary) and rapid response to a stimulus, which minimises any damage to the body from potentially harmful conditions, such as touching something hot. Reflex actions are therefore essential to the survival of many organisms.
