Stimulation of the vagus nerve decreases heart rate. The vagus nerve is an important part of the parasympathetic nervous system.
Both the parasympathetic and sympathetic nervous systems innervate the heart. The parasympathetic nervous system functions in regulating heart rate through the vagus nerve, with increased vagal activity producing a slowing of heart reate. The sympathetic nervous system has an excitatory influence on heart rate and contractlitiy, and it serves as the final common pathway for controlling the smooth muscle tone of the blood vessels.

The 'fight or flight' system also called the sympathetic system causes this response.
each and every part of body is controlled by the nervous system.
No, the brain is not part of the cardiovascular system. The cardiovascular system consists of the heart and blood vessels responsible for pumping and circulating blood throughout the body. The brain is part of the central nervous system and controls cognitive and physiological functions.
the part of the nervous system of vertebrates that controls involuntary actions of the smooth muscles and heart and glands
sympathetic system
The autonomic nervous system is a division of the peripheral nervous system that controls automatic responses in the body, such as the heart rate, hormone levels, gastrointestinal functions, and metabolism.
Parasympathetic division
lkhfiuhfsldhufshd
There are two parts of the autonomic nervous system-the sympathetic and the parasympathetic. The sympathetic nervous system initiates the fight-or-flight response, which increases heart rate, blood pressure, and cardiac output.
The somatic and autonomic nervous systems are part of the peripheral nervous system. The somatic nervous system controls voluntary movements and receives sensory information, while the autonomic nervous system regulates involuntary actions, such as heart rate and digestion.
although the heartbeat is not controlled by the nervous system,the autonomic nervous system does influence the heart rate.
