I
or oral cavity or buccal cavity

Orifice through which food and air enter the body.

It opens to the outside at the lips and empties into the throat at the rear and is bounded by the lips, cheeks, hard and soft palates, and glottis. Its chief structures are the teeth (see tooth), tongue, and palate. It is the site of chewing and speech formation. The mouth is lined by mucous membranes containing small glands that, along with the salivary glands, keep it moist and clear of food and other debris.
II
(as used in expressions)
foot and mouth disease
hoof and mouth disease

also called  Oral Cavity, or Buccal Cavity,  
 in human anatomy, orifice through which food and air enter the body. The mouth opens to the outside at the lips and empties into the throat at the rear; its boundaries are defined by the lips, cheeks, hard and soft palates, and glottis. It is divided into two sections: the vestibule, the area between the cheeks and the teeth, and the oral cavity proper. The latter section is mostly filled by the tongue, a large muscle firmly anchored to the floor of the mouth by the frenulum linguae. In addition to its primary role in the intake and initial digestion of food, the mouth and its structures are essential in humans to the formation of speech.

      The chief structures of the mouth are the teeth (tooth), which tear and grind ingested food into small pieces that are suitable for digestion; the tongue, which positions and mixes food and also carries sensory receptors for taste; and the palate, which separates the mouth from the nasal cavity, allowing separate passages for air and for food. All these structures, along with the lips, are involved in the formation of speech sounds by modifying the passage of air through the mouth.

      The oral cavity and vestibule are entirely lined by mucous membranes (mucous membrane) containing numerous small glands that, along with the three pairs of salivary glands, bathe the mouth in fluid, keeping it moist and clear of food and other debris. Specialized membranes form both the gums (gum) (gingivae), which surround and support the teeth, and the surface of the tongue, on which the membrane is rougher in texture, containing many small papillae that hold the taste buds. The mouth's moist environment and the enzymes within its secretions help to soften food, facilitating swallowing and beginning the process of digestion. See also digestion.
