Definition:Any measurement of or directly related to the part of the autonomic nervous system (the part of the nervous system that regulates involuntary action) that is concerned especially with preparing the body to react to situations of stress or emergency. The sympathetic nervous system contains chiefly adrenergic fibers and tends to depress secretion, decrease the tone and contractility of smooth muscle, and increase heart rate. The nervous system is the organ system which, along with the endocrine system, correlates the adjustments and reactions of the organism to its internal and external environment via transmission of information, in the form of electrochemical impulses, throughout the body.
