What is the Meaning of Sympathetic Nervous System?

The Sympathetic Nervous System (SNS) constitutes the primary division of the autonomic nervous system responsible for mobilizing the body's resources during acute stress, excitement, or physical exertion—the "fight or flight" response. Activation results in immediate physiological shifts, including increased heart rate, peripheral vasoconstriction, and bronchodilation, preparing the organism for immediate action. Chronic over-activation of the SNS is clinically associated with sustained high cortisol output and systemic inflammation, impacting overall hormonal resilience.

What is the Origin of Sympathetic Nervous System?

The term comes from the Greek sympatheia, meaning "suffering with" or "feeling with," describing its coordinated activation across various organs. It is anatomically one of the two main branches of the visceral motor system.

What is the Mechanism of Sympathetic Nervous System?

The SNS achieves its rapid effects primarily through the release of the neurotransmitter norepinephrine from postganglionic nerve terminals and the simultaneous release of epinephrine (adrenaline) from the adrenal medulla into the bloodstream. This dual action ensures widespread and rapid receptor binding across adrenergic receptors throughout the cardiovascular and metabolic systems. This acute hormonal surge temporarily prioritizes survival functions over long-term maintenance processes like digestion and reproduction.
