A structure which serves as both the roof of the mouth and the floor of the nasal cavity and nasopharynx. The palate has two parts: the hard palate and the soft palate. The hard palate, which is the anterior two-thirds of the palate, begins just behind the upper central teeth and is made up of bone. The soft palate, which is the posterior one-third of the palate, is made up of muscle; the soft palate is therefore movable, and it elevates to help with swallowing and speech.
