Mouth

In animal anatomy, the mouth is the first portion of the alimentary canal that receives food.

Some animal phyla, including vertebrates, have a complete digestive system, with a mouth at one end and an anus at the other. Which end forms first in ontogeny is a criterion used to classify animals into protostome and deuterostome. The first space of the mouth is the mouth cavity, bounded laterally and in front by the alveolar arches (containing the teeth), and posteriorly by the isthmus of the fauces.

Famous quotes containing the word mouth:

    Oh, that I knew where I might find him, that I might come even to his dwelling! I would lay my case before him, and fill my mouth with arguments. I would learn what he would answer me, and understand what he would say to me. Would he contend with me in the greatness of his power? No; but he would give heed to me. There an upright person could reason with him, and I should be acquitted forever by my judge.
    Bible: Hebrew, Job 23:3-7.

    Job, of God.

    Out of the mouth of babes and sucklings hast thou ordained strength
    because of thine enemies, that thou mightest still the enemy and the
    avenger.
    Bible: Hebrew Psalm VIII (l. VIII, 2)

    The great fact was the land itself, which seemed to overwhelm the little beginnings of human society that struggled in its sombre wastes. It was from facing this vast hardness that the boy’s mouth had become so bitter; because he felt that men were too weak to make any mark here, that the land wanted to be let alone, to preserve its own fierce strength, its peculiar, savage kind of beauty, its uninterrupted mournfulness.
    Willa Cather (1873–1947)
