Mouth parts are the various components that make up the mouth, including the LIPS, GUMS, palates, deltas, and uvulas. The LIPS are two fleshy folds that form the opening of the mouth and are used for speaking, eating, and facial expressions. GUMS are the soft tissue that surrounds and supports the teeth. Palates are the roof of the mouth, which is divided into two sections: the hard palate and the soft palate. Deltas are the small triangular-shaped pieces of tissue that separate the teeth. Lastly, the uvula is a small, fleshy projection that hangs down from the soft palate.
