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:
“When Pan sounds up his minstrelsy;
His minstrelsy! O base! This quill,
Which at my mouth with wind I fill,
Puts me in mind, though her I miss,
That still my Syrinx’ lips I kiss.”
—John Lyly (1553–1606)
“Speak the speech, I pray you, as I pronounced it to you—trippingly on the tongue; but if you mouth it, as many of your players do, I had as lief the town-crier spoke my lines. Nor do not saw the air too much with your hand, thus, but use all gently; for in the very torrent, tempest, and as I may say, the whirlwind of your passion, you must acquire and beget a temperance that may give it smoothness.”
—William Shakespeare (1564–1616)
“Folks don’t like to have somebody around knowin’ more than they do. It aggravates ‘em. You’re not gonna change any of them by talkin’ right, they’ve got to want to learn themselves, and when they don’t want to learn there’s nothing you can do but keep your mouth shut or talk their language.”
—Harper Lee (b. 1926)
