What else can I help you with?
Is the vagus nerve sympathetic or parasympathetic?
The vagus nerve is parasympathetic.
Which nerves contain the most parasympathetic preganglionic fibers a trigeminal b splanchnic c optic d vagus?
D. vagus. this is the largest Cranial nerve, carrying parasympathetic information to much of the body (ie. esophagus, GI tract, heart). parasympathetic fibers, unlike sympathetic fibers, do not synapse until they are pretty much on in or near the organ. So the vagus is made up of preganglionic parasympathetics.trigeminal contains somatic afferents, and somatic efferents. neither of these are visceral efferents (which could be para or sympathetic).wikipedia tells you correctly that splanchnic nerves are generally sympathetic autonomics, except for one spot.optic nerve is carrying Afferent sensory information Away from the eye.
The route of major parasympathetic outflow from the head is the?
The route of major parasympathetic outflow from the head is through the cranial nerve known as the vagus nerve (CN X). This nerve innervates many structures in the head, including the heart, lungs, and digestive system, to regulate functions such as heart rate, breathing, and digestion.
What is the function of the vagus nerve in the human body?
The vagus nerve is responsible for regulating various bodily functions, including heart rate, digestion, and breathing. It plays a crucial role in the parasympathetic nervous system, which helps the body relax and rest.
Which is the only cranial nerve to extend to the abdomen?
The vagus nerve (cranial nerve X) is the only cranial nerve that extends all the way down to the abdomen, providing parasympathetic innervation to organs in the chest and abdomen.
Is the vagus nerve sympathetic or parasympathetic?
The vagus nerve is parasympathetic.
Is the vagus nerve sympathetic?
No. The vagus nerve is in the parasympathetic system
What is the function of vagus nerve?
sympathetic fuction and the motor function mainly on the production of voice. http://www.answers.com/topic/vagus-nerve
What is the difference between the vagus nerve and the parasympathetic nerve relating to the respiratory system?
Vagus nerve has a lot of branches. Some of them form a motor supply to the muscle (thru recurrent laryngeal nerve) whereas some form a parasympathetic chain that supply the respiratory system and other system too (ie: Cardiovascular parasympathetic also supplied by the brach of vagus) The branches of the vagus that differ the motor function and the parasympathetic fuction related to the respiratory system.
Parasympathetic innervation of the stomach is provided by?
Parasympathetic innervation of the stomach is provided by the vagus nerve. The vagus nerve is located in the brain and is also known as the pneumogastric nerve.
What nerve initiates the SA node to initiate an impulse?
The sinoatrial (SA) node is innervated by the vagus nerve (parasympathetic) and sympathetic nerves. However, the sympathetic nerves play a more significant role in initiating an impulse in the SA node by releasing norepinephrine, which increases heart rate.
What nerves innervate the heart?
vagus nerve and sympathetic fibers
Do the vagus nerve increase heart rate?
it decreased heart rate , since vagus nerve innervate parasympathetic never and we know parasympathetic nerve reduce heart rate.
Vagal escape occurs when heart is stimulated by what?
Vagal escape occurs when the parasympathetic nervous system, specifically the vagus nerve, fails to regulate the heart rate and the heart muscle is instead stimulated by other mechanisms. This can happen in situations where there is a prolonged increase in sympathetic nerve activity or when there is a dysfunction in the parasympathetic nervous system.
What happens to your heart rate when you innervate your vagus nerve?
Stimulation of the vagus nerve decreases heart rate. The vagus nerve is an important part of the parasympathetic nervous system.

Which of these is stimulated by parasympathetic nerves?
Parasympathetic nerves stimulate resting and digesting. Therefore, stomach activity is stimulated by parasympathetic nerves.
