soft palate

the portion of the roof of the mouth that extends rearward from the hard palate and terminates at a fleshy appendage, the uvula. Consisting of fibromuscular tissue covered by mucous membrane, it separates the oral cavity from the nasopharynx and, when raised, closes off the nasopharynx to produce normal speech sounds. Also called velum palatinum.
