AP PSYCHOLOGY

Detailed explanation-1: -A spontaneous, automatic, involuntary, response to a stimulus that occurs without any conscious effort or thought and requires the involvement of the CNS, is known as the reflex action.

Detailed explanation-2: -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.

Detailed explanation-3: -A reflex is an involuntary (say: in-VAHL-un-ter-ee), or automatic, action that your body does in response to something-without you even having to think about it.

Detailed explanation-4: -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-5: -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.
