Talk:Vagus nerve

message: Where exactly is the vagus nerve? (asked 70.57.70.99).
* Well, like the article says: "starts in the brainstem (somewhere in the medulla oblongata) and extends way down past the head, all the way down to the abdomen." Don't know that I'd phrase it exactly like that, but it gets the idea across. -- Dcfleck 19:44, 2005 Apr 23 (UTC)
::Perhaps naming the organs enervated would be helpful? I know that it enervates as far south (distal) as the uterus and large colon. Thank you, Wordreader (talk) 12:50, 25 July 2014 (UTC)

message: I don't know if anyone wants to mention this, but the common boxing/martial arts knockouts from being hit on the chin are due to the jaws forcing back onto the Vagus nerves just behind the jaws. I thought that was a pretty neat fact.  Amnion (talk) 14:46, 18 September 2008 (UTC)

message: Please reference research backing: "Mild degree of intermittent VNS by daily performance of certain breathing exercises (Pranayama) over a period of several weeks lowers blood pressure and the heart rate in persons with elevated blood pressure and/or elevated heart rate."
Psychology today had useful articles which may provide a reference.  — Preceding unsigned comment added by 165.255.120.189 (talk) 23:35, 19 February 2018 (UTC)
thread_title:  Pranayama Reference 

message: I have a good friend who was about to undergo a vasectomy, when the doctor inserted a needle to numb the area my friend went into a seizure. The procedure was stopped and he was told to see a cardiologist. Before the appointment he was having trouble breathing, his heart would start to race and he was very tired. He went to the hospital but all cardiac tests showed nothing wrong. The symptoms still persist 3 weeks after their onset. Any information would be appreciated.

replies: text: There are several things wrong with that sentence and your proposed edit. It does not give motor inntervation down to the second third of the transverse colon, it gives parasympathetic all the way down to and inc.  2/3 of the transverse colon. It gives motor to diff muscles, as described already in the article. I would say that 'parasympathetic' is fine, although 'sensory parasympthetic' is not wrong.

thread_title:  Vagus nerve problems 

message: I suppose vagotonia would be the opposite of what is mentioned in the article as vagolytic innervation. Maybe that could be mentioned, as I am working on an article which references this term (vagotonia). __meco 16:33, 7 June 2006 (UTC)
thread_title:  Vagolytic v. vagotonia 

message: I believe these statements are incorrect: 
"Symptoms of nervousness, especially in a social context, such as increased heart rate/palpitation, impediment or inability to speak, stomach irritation, and excessive perspiration are caused in part by the vagus nerve.
An effective method of curbing these symptoms is by taking a deep breath, and forcefully blowing out through a small hole in your mouth, letting your cheeks puff out. This puts pressure on the nerve, and tells it to reset."
The symptoms mentioned are mostly due to increased sympathetic activity rather than withdrawal of resting vagal tone, and the maneuver described, sort of a mini-Valsalva, will act as a vagal stimulus alright, but the 'press the reset button' explanation is lacking.Moioci 02:25, 13 July 2006 (UTC)
replies: text: Moioci is correct. Stimulation of the Vagus nerve decreases the heart rate and the blood pressure, too. Thus, the mini-Valsalva was mentioned. Depending on your personal physiology, use it with caution, though. Ask your MD first. Thank you, Wordreader (talk) 13:13, 25 July 2014 (UTC)
thread_title:  Backwards Explanation 

message: I have recently seen a Chinese Dr regarding why I am always so tired and rundown.  Yes I do have a 21 month old son, however I new it was more than that as my fatigue goes back at least 7 years (I am now 33).  He looked at me for only a few minutes and explained that my Vagus nerve on my left side was being jammed by extremely tight neck muscles. This was pushing on my wind pipe making it difficult for me to get a full breath.  Also I believe (but do not fully understand as yet) that it is also pushing on my Pitutitary Gland and thus effecting my adrenals.  Both these problems would create a very marked drop in my energy levels.  
Any comments or further explainations regarding this would be appreciated.

message: I have been hearing in the news about losing weight by having the Vagus nerve cut. Now I caught the tail end of the report and I was unable to get more info. Is there any info on this subject.

thread_title:  Vagus Nerve and Weight loss 

message: May I suggest that the innervation section be subdivided into smaller sections with the following headings: motor, somatosensory, special sensory, autonomic? The meat of this article should be the functions and pathway of the nerve, not the extraneous facts that make up the majority of it currently.
Activation of the vagus nerve typically leads to a reduction in heart rate, blood pressure, or both. This occurs commonly in the setting of gastrointestinal illness such as viral gastroenteritis or acute cholecystitis
I think a reference should be provided for such a statement. As a doctor, I have never heard of this effect, and a quick seearch on pubmed, I could only find some weak animal studies

thread_title:  Better organization for "innervation" section needed 

message: Thank you for deleting the word "simply". Good call. 
However, for the rest of your change, can you provide your source? "The vagus nerve [. . .], also called the pneumogastric nerve, is known as the tenth cranial nerve or CNX, and interfaces primarily with the stomach." I doubt that the women I've met who are flat on the floor, diaphoretic with an alarming pallor, due to vagal stimulation from severe menstrual cramps would agree with you about the stomach thing. I've never met anyone in my personal life suffering a vasovagal episode from stomach distress, but in college, it happens a lot to menstruating women. The culprit seems to be excess prostaglandins that increase the severity of the cramps that in turn stimulate the vagus nerve (along with other uncomfortable effects). This UCSD site explains the effects of prostaglandins on menstruation: "Painful Periods (Dysmorrhea)", Student Health Services, University of California San Diego, http://studenthealth.ucsd.edu/painfulperiods.shtml. Uterine tumors can also cause severe cramping leading to vasovagal episodes. Thank you, Wordreader (talk) 20:20, 9 August 2014 (UTC)
thread_title:  Br77ino's lede changes 

message: If the level of English was chosen to explain Vagus nerve 
to people who already know what it is - this article 
may be just fine.
However, if this article is intended to explain Vagus nerve 
to those (such as me) who do NOT know what it is - this 
article is a near complete failure.
After perusing the opaque article, I still have little idea 
where it is so I can't even suggest any new language.

replies: text: Also, the question of *where* the vagus nerve is located is complex. It starts in the brain, exits from a hole in the bottom corner of the skull (not the big hole with the spinal cord), travels down the front of the neck on each side (in front of the SCM muscle), then interweaves like lace in the walls of the esophagus. Here the left and right vagus become completely mixed and after this point they both travel to the various organs: heart, lungs, and most of the other organs in the abdomen down to a certain point in the large intestine. Hope that helps - I've tried to phrase it in common terms. However, I don't have printed citations to add for this, it's just what I learned in science lectures, so more book time is needed for trying to improve the article in a meaningful way.

thread_title:  Role in appetite, mood etc 

message: The  makes claims of a sympathetic function via peripheral chemoreceptors that has remained without a source to back it up for at least a year. There is a citation but it is to a page that updates frequently that does not currently back up the claims. I am unable to find anything to support the claims. The closest I've found is  but although this backs up a sympathetic component it doesn't mention chemoreceptors. I have for now removed the claims until a supporting source can be found.
