Detailed explanation-1: -The visceral (or autonomic) motor system controls involuntary functions mediated by the activity of smooth muscle fibers, cardiac muscle fibers, and glands.
Detailed explanation-2: -Although most of the autonomic nervous system responses are involuntary, they can integrate with the somatic nervous system, which is responsible for the voluntary movements.
Detailed explanation-3: -The visceral motor system is regulated in part by circuitry in the cerebral cortex: Involuntary visceral reactions such as blushing in response to consciously embarrassing stimuli, vasoconstriction and pallor in response to fear, and autonomic responses to sexual situations make this plain.
Detailed explanation-4: -Heart rhythm problems (including arrhythmias). Dizziness or passing out when standing up. Trouble swallowing (dysphagia). Trouble digesting food (including gastroparesis). Constipation. Incontinence (bladder or bowel). Sexual dysfunction. More items •15-Jun-2022
