Question

write the effect of sympathitic and parasympathetic nervous system on heart

Answer 1

Hey buddy

here is your answer..........

effect of parasympathetic nervous system on heart :

parasympathetic nervous system(vagal nerves to the heart) increases the resting potential and decreases the rate of diastolic depolarization; under these circumstances the heart rate slows.

effect of sympathitic nervous system on heart :

The sympathetic nervous system (SNS) releases the hormones (catecholamines - epinephrine and norepinephrine) to accelerate the heart rate. ... The reduced heart rate results from an increase in activity of the parasympathetic nervous system, and perhaps from a decrease in activity of the sympathetic nervous system.
