What are the functions of the vagus nerve?

he vagus nerve supplies motor parasympathetic fibers to all the organs except the suprarenal glands, from the neck down to the second segment of the transverse colon. The vagus also controls a few skeletal muscles, namely:
* Levator veli palatini muscle
* Salpingopharyngeus muscle
* Palatoglossus muscle
* Palatopharyngeus muscle
* Superior, middle and inferior pharyngeal constrictors
* Muscles of the larynx (speech).
This means that the vagus nerve is responsible for such varied tasks as heart rate, gastrointestinal peristalsis, sweating, and quite a few muscle movements in the mouth, including speech (via the recurrent laryngeal nerve) and keeping the larynx open for breathing. It also receives some sensation from the outer ear, via the Auricular branch (also known as Alderman's nerve) and part of the meninges.

The Vagus nerve controls a number of visceral functions, all of those that others have listed, also such interesting body phenomena as vomiting, hiccupping, and the gag reflex. My daughter, while studying for her entrance exams, developed a nervous reaction in her Vagus nerve, and I told her what the trouble was. She replied, "Do you think if I go to Las Vegas I'll get better?" She was joking, of course, she knows better than that. But I thought that was kinda cute.

Key-in and Google or Jeeves the term; you'll find it there.
The vagus, a considerably major nerve, which runs from the abdominal area, splitting in two like a fork and proceeding clear downward and through both legs -- a command nerve of the body indeed...controlling many functions, without which function your mobility and other facilities to say the least would be incapacitated.

The vagus nerve is associated with visceral functions. Applying pressure to this nerve will slow a rapid heartbeat. Also this nerve is stimulated when one "bear's down"...like when going to the bathroom.

It is the seconds longest nerve in the body. It controlls the heart from the brain.
