The roof of the mouth, which is covered with mucous membrane and which separates the mouth from the nasal cavity. At the front is the hard palate, a plate of bone forming part of the maxilla. At the rear is the soft palate, a flap of muscle and fibrous tissue that projects into the pharynx.
(See also cleft lip and palate.)
The partition between the cavity of the mouth, below, and that of the nose, above. It consists of the hard palate towards the front, which is composed of a bony plate covered below by the mucous membrane of the mouth, above by that of the nose; and of the soft palate further back, in which a muscular layer, composed of nine small muscles, is similarly covered. The hard palate extends a little further back than the wisdom teeth, and is formed by the maxillary and palate bones. The soft palate is concave towards the mouth and convex towards the nose, and it ends behind in a free border, at the centre of which is the prolongation known as the uvula. When food or air is passing through the mouth, as in the acts of swallowing, coughing, or vomiting, the soft palate is drawn upwards so as to touch the back wall of the throat and shut o? the cavity of the nose. Movements of the soft palate, by changing the shape of the mouth and nose cavities, are important in the production of speech.
n. the roof of the mouth, which separates the mouth from the nasal cavity and consists of two portions. The hard palate, at the front of the mouth, is formed by processes of the maxillae and palatine bones and is covered by mucous membrane. The soft palate, further back, is a movable fold of mucous membrane that tapers at the back of the mouth to form a fleshy hanging flap of tissue – the uvula. —palatal adj.
