Its general action is to mobilize the body's nervous system fight-or-flight response. It is, however, constantly active at a basic level to maintain homeostasis.

Famous quotes containing the words sympathetic, nervous and/or system:

    1992 is not a year I shall look back on with undiluted pleasure. In the words of one of my more sympathetic correspondents, it has turned out to be an Annus Horribilis.
    Elizabeth II (b. 1926)

    He was the finest of our happy men;
    He had all joys, he never thought of death;
    He fiddled sometimes with his mind, and then
    Shook off the tremor like a nervous wren....
    Allen Tate (1899–1979)

    The human body is not a thing or substance, given, but a continuous creation. The human body is an energy system ... which is never a complete structure; never static; is in perpetual inner self-construction and self-destruction; we destroy in order to make it new.
    Norman O. Brown (b. 1913)
