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:

    “Father, Son, and Holy Ghost,
    So I make an idle boast;
    Jesus of the twice-turned cheek
    Lamb of God, although I speak
    With my mouth thus, in my heart
    Do I play a double part.”
    —Countee Cullen (1903–1946)

    “Do you not see that whatever goes into the mouth enters the stomach, and goes out into the sewer?”
    —Bible: New Testament, Matthew 15:17.

    “May Allah keep her
    And other wives from me. But this young slave
    For the Caliph? Well, only her thin mouth to save
    My soul I can’t forget, nor her slack eyes:
    The oasis of age is sand and lies.”
    —Allen Tate (1899–1979)
