Is autonomic central system part of central nervous 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.
Which nervous system dominates the control of effector organs under normal everyday conditions?
The autonomic nervous system dominates the control of effector organs under normal everyday conditions. It consists of the sympathetic and parasympathetic divisions, which work together to maintain homeostasis by regulating functions such as heart rate, digestion, and respiration without conscious effort.
What does the parasympathetic nervous system do in the body?
The parasympathetic nervous system helps regulate the body's rest and digest functions, such as slowing heart rate, promoting digestion, and conserving energy.
What is the function of the parasympathetic nervous system in the body?
The parasympathetic nervous system helps regulate the body's rest and digest functions, such as slowing heart rate, promoting digestion, and conserving energy.
The effects of the sympathetic nervous system are essentially opposite of which nervous system?
The effects of the sympathetic nervous system are essential opposite those of the parasympathetic nervous system. The sympathetic nervous system accelerates functions such as heart rate and breathing and the parasympathetic slows these bodily processes down. The sympathetic also inhibits digestion, whereas the parasympathetic stimulates digestion. The sympathetic nervous system produces "fight-or-flight" reactions, while the parasympathetic functions under relaxed conditions.
Decreasing heart rate is under the control of what nervous division?
The parasympathetic division of the autonomic nervous system is responsible for decreasing heart rate. It releases acetylcholine to slow down the heart's activity.
Which nervous system controls involuntary functions such as heart rate and digestion and is divided into the sympathetic nervous system and the parasympathetic nervous system?
The autonomic nervous system is divided into the sympathetic and parasympathetic systems.
What does the parasympathetic nervous system release to affect heart rate?
epinephrine
Is autonomic central system part of central nervous system?

What is the antagonistic nerves to the parasympathetic nervous system?
The sympathetic nervous system is antagonistic to the parasympathetic nervous system. It is responsible for the "fight or flight" response, increasing heart rate, dilating airways, and mobilizing energy stores, in contrast to the parasympathetic system's role in promoting relaxation and digestion.
Which nervous system dominates the control of effector organs under normal everyday conditions?
The autonomic nervous system dominates the control of effector organs under normal everyday conditions. It consists of the sympathetic and parasympathetic divisions, which work together to maintain homeostasis by regulating functions such as heart rate, digestion, and respiration without conscious effort.
What does the parasympathetic nervous system do in the body?
The parasympathetic nervous system helps regulate the body's rest and digest functions, such as slowing heart rate, promoting digestion, and conserving energy.
What part of the nervous system that regulates heart beat digestion?
Parasympathetic division

Regulates heart activity via the vagus nerve?
The vagus nerve plays a key role in regulating heart activity by controlling the parasympathetic nervous system. Stimulation of the vagus nerve can slow down heart rate and decrease blood pressure, helping to maintain cardiovascular function and stability. It acts as the main connection between the brain and the heart for controlling heart rate and other cardiac functions.
Does the parasympathetic nervous system increase or decrease heart rate?
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.
