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:
“your antlers like seaweed,
your face like a wolf’s death mask,
your mouth a virgin, your nose a nipple,
your legs muscled up like knitting balls,
your neck mournful as an axe....”
—Anne Sexton (1928–1974)
“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)
“Out of a dog’s mouth will never come ivory tusks.”
—Chinese proverb.
