What about sympathetic nervous?
- The sympathetic nervous system is a portion of the nervous system that is responsible for producing reflex cardiovascular system adjustments as well as localized adjustments (like sweating in response to a rise in body temperature).
- The sympathetic nervous system's primary actions include expanding blood vessels, raising blood pressure, contracting muscles, releasing sweat from sweat glands, widening bronchi to allow for greater oxygen exchange, and contracting the heart, all of which aid in the body's preparation for emergency situations.
- The sympathetic nervous system can increase blood pressure, widen bronchial passages, decrease large intestine motility, constrict blood vessels, make pupils dilated, cause goosebumps, and activate sweat glands.
- Along with its opposite, the parasympathetic nervous system, the sympathetic nervous system is a component of the autonomic nervous system.
- The thoracic and lumbar spinal cord segments, collectively referred to as the thoracolumbar division, are where the sympathetic nervous system originates (T1 to L2,3).
