hard palate  the front portion of the palate, braced by the upper jaw bones (maxillae) and separating the cavities of the mouth and nose.

premaxillary palate  , primary palate  the first part of the palate to form in embryonic development, representing a small triangular region anterior to the incisive fossa in the adult palate.

secondary palate  in embryonic development, the part of the palate that forms later than the primary palate; it represents most of the adult hard and soft palates.

soft palate  the fleshy part of the palate, arching downward from the hard palate to the throat, and separating the mouth and the pharynx. When a person swallows, the rear of the soft palate swings up against the back of the pharynx and blocks the passage of food and air to the nose. A fleshy lobe called the uvula hangs from the middle of the back edge of the soft palate.
