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:
“Pull down the blinds, bring fiddle and clarionet
That there be no foot silent in the room
Nor mouth from kissing, nor from wine unwet;
Our Father Rosicross is in his tomb.”

“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....”
