The <u>autonomic</u> nervous system provides involuntary regulation of smooth muscle, cardiac muscle, and glandular activity.
The peripheral nervous system's autonomic nervous system controls physiologic functions including digestion, breathing, blood pressure, and sexual arousal in addition to other involuntary functions like heart rate. It is divided into sympathetic, parasympathetic, and enteric regions, each of which has a unique anatomical structure. Some bodily functions, like blood pressure and respiratory rate, are regulated by the autonomic nervous system. The paraventricular nucleus of the hypothalamus is the critical brain region for the central regulation of the autonomic nervous system. Autonomic neuropathy most frequently results from diabetes. Infections with viruses or bacteria, certain drugs, or other medical disorders might potentially be the reason. The type of injured nerve affects the symptoms and course of therapy.
