===Sympathetic (Adrenergic) Nervous System===
The adrenergic nervous system is a vital component of many processes throughout the body, including the cardiovascular system. Circulating catecholamines (e.g. adrenaline and noradrenaline) bind to and activate adrenergic receptors on cell membranes. Adrenergic receptors are a class of G-protein coupled receptors that elicit a variety of tissue-specific effects and exist in several subtypes.
