1. Sympathetic nervous system

   The sympathetic nervous system (SNS) is one of the three divisions of the autonomic nervous system, the others being the parasympathetic nervous system and the enteric nervous system. The enteric nervous system is sometimes considered part of the autonomic nervous system, and sometimes considered an independent system.The autonomic nervous system functions to regulate the body's unconscious actions. The sympathetic nervous system's primary process is to stimulate the body's fight or flight response. It is, however, constantly active at a basic level to maintain homeostasis. The sympathetic nervous system is described as being antagonistic to the parasympathetic nervous system which stimulates the body to "feed and breed" and to (then) "rest-and-digest".

1. sympathetic nervous system

   The sympathetic nervous system is a part of the autonomic nervous system that controls the body's 'fight or flight' reactions in response to perceived threats. It stimulates changes in the body such as increased heart rate, dilation of the pupils, slowing of digestion, and release of adrenaline, allowing the body to react quickly and effectively to dangerous situations. It works in balance with the parasympathetic nervous system, which controls rest and digestion.

1. Sympathetic Nervous System

   The thoracolumbar division of the autonomic nervous system. Sympathetic preganglionic fibers originate in neurons of the intermediolateral column of the spinal cord and project to the paravertebral and prevertebral ganglia, which in turn project to target organs. The sympathetic nervous system mediates the body's response to stressful situations, i.e., the fight or flight reactions. It often acts reciprocally to the parasympathetic system.
