Cavitas Oris

Cavitas Oris

The oral cavity is divided into the oral cavity proper and the vestibule

Vestibule – This space is between the cheeks and lips externally and the teeth and gums internally. Two muscular fleshy folds -the lips, surround the oral fissure. Skin covers the lips externally, and the interior is lined with a mucous membrane.

Median folds – mucous membrane called the labial frenulae connect the lips to the gums. The lips contain the orbicularis oris, which puckers the lips and is sometimes referred to as the kissing muscle. The little groove that runs from the upper lip toward the nose is called the philtrum

Oral cavity proper – includes everything behind the teeth. The roof of the mouth is formed by the hard palate, and the floor is formed by the anterior two-thirds of the tongue and the mucous membrane that covers the sides of the tongue and attaches it to the mandible.
