Path
The cranial root fibers arise from the cells of the nucleus ambiguus and emerge as four or five delicate rootlets from the side of the medulla oblongata, below the roots of the vagus.
It runs lateralward to the jugular foramen, where it may interchange fibers with the spinal portion or even become united to it for a short distance; here it is also connected by one or two filaments with the jugular ganglion of the vagus.
It then passes through the jugular foramen, separates from the spinal portion and is continued over the surface of the ganglion nodosum of the vagus, to the surface of which it is adherent, and is distributed principally to the pharyngeal and superior laryngeal branches of the vagus. Through the pharyngeal branch it probably supplies the Musculus uvulæ and Levator veli palatini. Some few filaments from it are continued into the trunk of the vagus below the ganglion, to be distributed with the recurrent nerve and probably also with the cardiac nerves.

Famous quotes containing the word path:
“Today brings the sad, glad tidings that Mrs. Abraham Lincoln has passed from that darkness which had fallen upon her path through this life, out into the light and joy of that life toward which her vision has so long been strained.
Modern education is lethal to children.... We stuff them with mathematics, we pummel them with science, and we use them up before their time.”
—Honoré De Balzac (1799–1850)
“So-called “austerity,” the stoic injunction, is the path towards universal destruction. It is the old, the fatal, competitive path. “Pull in your belt” is a slogan closely related to “gird up your loins,” or the guns-butter metaphor.”
—Wyndham Lewis (1882–1957)
“It is the way unseen, the certain route,
Where ever bound, yet thou art ever free;
The path of Him, whose perfect law of love
Bids spheres and atoms in just order move.”
—Jones Very (1831–1880)
