The autonomic nervous system (ANS) is a branch of the peripheral nervous system (PNS) that regulates the function of the viscera.It innervates smooth muscle as well as glands and is further divided into the parasympathetic and sympathetic systems.. Consequently, up to 91% of patients in the United States remain undiagnosed, and Both classic and more recent (4, 5) models of emotional processing assume that subjective emotional feelings are triggered by the perception of emotion-related bodily states that reflect changes in the skeletomuscular, neuroendocrine, and autonomic nervous systems ().These conscious feelings help the individuals to voluntarily fine-tune their behavior to better The term feeling is closely related to, but not the same as emotion.
