Under conditions of stress, the entire sympathetic nervous system is activated, producing an immediate widespread response called the fight-or-flight response.
What happens when the sympathetic nervous system is stimulated?
eg, the sympathetic nervous system can accelerate heart rate, widen bronchial passages, decrease motility (movement) of the large intestine, constrict blood vessels, cause pupil dilation, activate goose bumps, start sweating and raise blood pressure.
What occurs during sympathetic activation?
In the heart (beta-1, beta-2), sympathetic activation causes an increased heart rate, the force of contraction, and rate of conduction, allowing for increased cardiac output to supply the body with oxygenated blood.
