List of terms related to Mouth


The oral cavity includes the lips, hard palate (the bony front portion of the roof of the mouth), soft palate (the muscular back portion of the roof of the mouth), retromolar trigone (the area behind the wisdom teeth), front two-thirds of the tongue, gingiva (gums), buccal mucosa (the inner lining of the lips and cheeks), and floor of the mouth under the tongue.



  • The mouth, or oral cavity, is the first part of the digestive tract.
  • It is adapted to receive food by ingestion, break it into small particles by mastication, and mix it with saliva.


The lips, cheeks, and palate form the boundaries.

Salivary secretions

The oral cavity contains the teeth and tongue and receives the secretions from the salivary glands.

Lips and Cheeks

The lips and cheeks help hold food in the mouth and keep it in place for chewing.

Role in speech

The mouth, tongue, cheeks, and vocal chords all play part in the formation of words for speech.

Testing texture of food

The lips contain numerous sensory receptors that are useful for judging the temperature and texture of foods.

  • The palate is the roof of the oral cavity.
  • It separates the oral cavity from the nasal cavity.
  • The anterior portion, the hard palate, is supported by bone.
  • The posterior portion, the soft palate, is skeletal muscle and connective tissue.
  • Posteriorly, the soft palate ends in a projection called the uvula.
  • During swallowing, the soft palate and uvula move upward to direct food away from the nasal cavity and into the oropharynx.
