Which of the following characteristics apply to the autonomic nervous system? Not under conscious control, activated by centers in the cerebral cortex, divided into sympathetic and parasympathetic divisions, controls smooth muscle throughout the body, composed of the brain and spinal cord. Incorrect: One or more selected answers are incorrect. The autonomic nervous system controls many processes throughout the body such as digestion, hormone release, and pupil dilation. Consider the role that consciousness has on these processes. Which parts of the brain are involved in these types of processes? Additionally, consider that skeletal muscle is the type of muscle that results in voluntary movement.
