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)

[edit] Pranayama Reference

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."

[edit] Vagus nerve problems

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.

Sorry, but this is the wrong place to ask for medical advice. I hope your friend recovers. -Will Beback 21:25, 7 March 2006 (UTC)

This nerve supplies motor and sensory parasympathetic fibers to virtually everything from the neck down to the first third of the transverse colon can i change that? cause like this one could think it gies motor innervation to everything til the transverse colon, and if i remember right its down to the two thirds of the transverse colon. And is it ok to say sensory parasympathetic? why not simply parasympathetic, without sensory. Someone explain me please user:gaboo

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.

[edit] Effects of cutting vagus nerve

What symtoms would someone expect if the Vagus nerve was cut during a hiatal hernia operation? Will this nerve grow back together without surgery over time? -- unsigned comment by 70.255.180.205, 5/3/2006

[edit] Vagolytic v. vagotonia

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)


[edit] Backwards Explanation

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)

[edit] Outrunning the Vagus Nerve

I was chatting to a friend about vagus nerve, and apparently it tells you when you are full (have eaten enough). There is nothing in this article about that sensation, or 'outrunning the vagus nerve' (eating as much as you can in the 20 minutes before the nerve recognises that you are full). Is this all correct? —Preceding unsigned comment added by 137.166.4.130 (talk) 04:01, August 25, 2006 (UTC)

[edit] "Full-time fetus"?

The vagus nerve is a pathway not an interpreter. It carrys the message to a part of the brain that then interprets the message that you are full. get a decent medical book and its quite simple. ( tutoria)

[edit] Vagus Nerve and Acupuncture

The comment regarding the rare occurance of accupunture hitting the vagus nerve needs better attribution/verification/citation. The link to the rotary club and yingyang website do not back up the statement. User:J. Bryant Evans 03:20, 6 April 2007 (UTC)

    • Please don't think I am questioning you -- I'm not. Just needs the reference you are searching for. JBEvans 03:28, 6 April 2007 (UTC)
      • Oh not at all, hope that wasn't short. You're absolutely right, it needs a citation. User:Sweetmoose6
Dizziness and fainting have been reported from acupuncture, but I've never heard of seizure attributed to injury of the vagus nerve. It's not reported anywhere at Pubmed, and seems anatomically unlikely. I'm removing it pending a reliable source. The problem with unsourced anecdotal claims is addressed at WP:NOTTRUTH. Thanks, Jim Butler(talk) 07:29, 7 April 2007 (UTC)
In the interest of full disclosure my post was deleted by an accupuncturist. The inclusion of my post could have been perceived as a negative occurence (bad for business), and was deleted because our ever so reliable media could not be depended on to produce the story. While rare, this is a documented occurence and should be examined. User: Sweetmoose6
Actually, I deleted it precisely because there was no documentation. If there is any, go ahead and provide it. If all you can do is resort to a gratuitious attack on my motivations, your argument isn't very strong. Have a look at WP:AGF, please. --Jim Butler(talk) 23:48, 7 April 2007 (UTC)
Then I owe you an apology. You're correct about the source issue as I have already stated. I assume when a source is found you will have no problem with its inclusion. But as to motivation, there are millions of unsourced statements and anecdotes on Wikipedia (although you are again correct that they are against the policy etc., should be corrected). It was just curious that an accupuncturist was so quick to remove a potentially very negative story about a serious problem that occured as the result of an accupuncture. I honestly apologize if that inference was incorrect. The purpose was to put the story out there so a source could be found where I have not been able to do so. This type of event has occured before in other places, so it is not an extreme medical claim. User:Sweetmoose6
"This type of event has occured before in other places" -- really? Citation, please? And thanks, apology accepted. The place to enlist help with sourcing is right here on the article talk page, cf. 2nd para of Wp:v#Burden_of_evidence. regards, Jim Butler(talk) 05:09, 8 April 2007 (UTC)

[edit] Vagus Nerve jamming causing fatigue

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.

Dude - Go to a doctor. This is not WebMD.Ndriley97 (talk) 00:10, 19 April 2008 (UTC)

[edit] Vagus Nerve and Weight loss

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.
