what effect does the nervous system have on the heart rate? stimulation by sympathetic nerves sets the resting heart rate of the

pacemaker cells in the sa node. stimulation by sympathetic nerves causes the pacemaker cells of the av node to depolarize more rapidly than the pacemaker cells of the sa node. stimulation by either the sympathetic or parasympathetic nerves causes pacemaker cells in the sa node to depolarize more slowly. stimulation by parasympathetic nerves causes the heart rate to slow down. the nervous system does not directly affect the heart rate.

The effect nervous system has on the heart rate is

Stimulation by parasympathetic nerves causes the heart rate to slow down.

The two branches of the autonomic (involuntary) nervous system regulate heart rate. The parasympathetic nervous system and the sympathetic nervous system (SNS and PNS) (PNS). To increase heart rate, the sympathetic nervous system (SNS) produces the catecholamines epinephrine and norepinephrine. The hormone acetylcholine is released by the parasympathetic nervous system (PNS) to reduce the heart rate. Your heart rate may briefly increase due to stress, coffee, and excitement, whereas it may temporarily decrease due to meditation or deep, steady breathing. Any amount of exercise will raise your heart rate, which will stay up as long as you keep exercising.

kari74 [83]

[ C. Coriolis Effect ]

If the Earth didn't rotate, winds would travel north or south because of the differences in pressure and temperature. The Earth does rotate, so, the Coriolis Effect diverts the wind to the left of the Southern Hemisphere and right of the Northern Hemisphere. The Coriolis Effect is very important because it creates cyclonic weather system.s

Best of Luck!
