Question

Quizplus · Accepted Answer

Spinal reflexes are automatic, unconscious responses to stimuli that are integrated within the spinal cord. Examples of spinal reflexes include the withdrawal reflex, knee-jerk reflex, and pupil dilation reflex. The other choices listed involve complex physiological processes that involve higher brain centers, not just spinal reflexes. Hormone secretion is regulated by the endocrine system, which involves the hypothalamus, pituitary gland, and other glands. Erection and ejaculation involve the autonomic nervous system, which is regulated by the brainstem and higher brain centers. Pain perception and withdrawal involve both spinal reflexes and higher brain centers.
