What are the general functions of the sympathetic nervous system and the parasympathetic nervous system?
The sympathetic and parasympathetic nervous systems are part of the autonomic nervous system (ANS) which innervates (supplies) smooth muscle, glands, and cardiac muscle.
- The sympathetic (thoracolumbar) nervous system deals with the fight-or-flight response. It gets the body ready to deal with emergency situations by increasing heart rate, dilating the pupils and airways, decreasing digestive tract motility, and stimulating adrenal glands and sweat glands.
- The parasympathetic (craniosacral) nervous system restores the body to homeostasis after a stressful or traumatic event/situation. It stimulates the body to decrease heart rate, increase digestive tract motility, constrict pupils, produce tears and saliva, and stimulate thoracic and abdominal viscera.

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.
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.
Sympathetic and parasympathetic nervous system's are subdivisions of what nervous system?
The sympathetic and parasympathetic nervous systems are subdivisions of the autonomic nervous system.
Ephinephrine is secreted from sympathetic or parasympathetic nervous system?
the ephinephrine is secreted from sympathetic or parasympathetic
What is between the sympathetic and the parasympathetic nervous system?
The parasympathetic and sympathetic divisions of the autonomic nervous system or antagonistic. They have opposing effects.
What is the relationship between the parasympathetic nervous system and the autonomic nervous system?
The parasympathetic nervous system is a division of the autonomic nervous system. It works in opposition to the sympathetic nervous system to regulate bodily functions at rest and promote relaxation.
Is the autonomic nervous system primarily sympathetic or parasympathetic in its function?
The autonomic nervous system has two main branches: sympathetic and parasympathetic. The sympathetic branch is responsible for the "fight or flight" response, while the parasympathetic branch is responsible for the "rest and digest" response. Both branches work together to maintain balance in the body's functions.
What system of the peripheral nervous system is further divided into the sympathetic and parasympathetic divisions?
The parasympathetic and sympathetic systems are branches of the autonomic nervous system.
What are the autonomic nervous system?
parasympathetic and sympathetic nervous systems
What are the two nervous systems?
parasympathetic and sympathetic nervous systems
Does morphine affect the parasympathetic or the sympathetic nervous system?
Sympathetic
How do sympathetic and parasympathetic nerves work together in the autonomic nervous system?
Sympathetic and parasympathetic nerves work together in the autonomic nervous system to regulate involuntary bodily functions. The sympathetic nervous system activates the "fight or flight" response, increasing heart rate and blood pressure, while the parasympathetic nervous system promotes relaxation and digestion. These two systems work in balance to maintain homeostasis in the body.
