SYMPATHETIC NERVOUS SYSTEM Meaning and Definition

1. The sympathetic nervous system refers to a division of the autonomic nervous system that primarily operates in response to stress, danger, or any situation requiring the preparation of the body for action. It is responsible for the body's "fight-or-flight" response, which encompasses physiological changes geared towards survival. This system consists of a network of nerves located in the spinal cord and ganglia, extending throughout the body.

   When activated, the sympathetic nervous system triggers a range of physiological responses aimed at increasing alertness, boosting energy, and preparing the body for physical exertion. It releases stress hormones, such as adrenaline and noradrenaline, into the bloodstream, causing various effects throughout the body. Some of these effects include increased heart rate, dilation of blood vessels, heightened blood pressure, enhanced blood sugar levels, and increased respiratory rate, all of which promote a higher level of physical readiness.

   Furthermore, the sympathetic nervous system also regulates other bodily functions unrelated to the fight-or-flight response. For instance, it influences the constriction of certain muscles and blood vessels, governs the release of neurotransmitters, and controls sweat production.

   Overall, the sympathetic nervous system plays a crucial role in facilitating rapid responses to stress and maintaining optimal bodily functions. Its intricate network enables seamless communication between organs, allowing the body to adapt, respond, and prepare for various situations, ensuring survival and overall well-being.
