Cranial Root of Accessory Nerves - Path

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:

    “Whoever heeds instruction is on the path to life, but one who rejects a rebuke goes astray.”
    —Bible: Hebrew, Proverbs 10:17.

    “... my aim is now, as it has been for the past ten years, to make myself a true woman, one worthy of the name, and one who will unshrinkingly follow the path which God marks out, one whose aim is to do all of the good she can in the world and not be one of the delicate little dolls or the silly fools who make up the bulk of American women, slaves to society and fashion.”
    —Ellen Henrietta Swallow Richards (1842–1911)

    “Imagination places the future world for us either above or below or in reincarnation. We dream of travels throughout the universe: is not the universe within us? We do not know the depths of our spirit. M The mysterious path leads within. In us, or nowhere, lies eternity with its worlds, the past and the future.”
    —Novalis [Friedrich Von Hardenberg] (1772–1801)
