Question

Quizplus · Accepted Answer

A reflex occurs when a stimulus triggers a rapid and involuntary response through direct connections between sensory and motor neurons, bypassing conscious control in the brain. This typically involves the spinal cord and sometimes other parts of the nervous system, but not exclusively so. Choice B) and D) are incorrect because not all brain activity is reflexive, and not all reflexive behavior is unrelated to conscious control. Choice C) is incorrect because some basic reflexes do not require involvement of the spinal cord.
