What are the sympathetic nervous system and the parasympathetic nervous system divisions of?
The autonomic nervous system.
Both are divisions of the autonomic nervous system.
What is the difference in function of the sympathetic and parasympathetic divisions of the autonomic nervous system as specifically relates to the operation of the cardiovascular system?
You have central and peripheral nervous system. This is anatomical or structural division. You have somatic as well as autonomic nervous system. It is the autonomic nervous system, that has got sympathetic as well as parasympathetic divisions. This is functional division. Somatic nervous system as well as autonomic nervous system has got central as well as peripheral components.
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.
What is the difference in function of the sympathetic and parasympathetic divisions of the autonomic nervous system as specifically relates to the operation of the cardiovascular and digestive system?
The autonomic nervous system is in charge of involuntary functions. There are two divisions-the sympathetic and parasympathetic. The sympathetic nervous system initiates the fight-or-flight response in emergency situations. The parasympathetic nervous system is referred to as the "rest and digest" stage in which the body "slows down" after the fight-or-flight response.
Which nervous system division controls smooth muscle contraction and secretion in the digestive system?
Autonomous nervous system. Consisting of Parasympathetic nervous system and Sympathetic nervous system. Parasympathetic nervous system increases the secretions of digestive tract and Sympathetic system decreases the secretions. Parasympathetic system increases the contractions of smooth muscles and increases the rate and force of peristalsis and Sympathetic system does vise verse.
