MeSH Palate
Dorlands/Elsevier Palate

The palate (pronounced /ˈpælɨt/) is the roof of the mouth in humans and other mammals. It separates the oral cavity from the nasal cavity.[1] A similar structure is found in crocodilians, but, in most other tetrapods, the oral and nasal cavities are not truly separate. The palate is divided into two parts, the anterior bony hard palate, and the posterior fleshy soft palate or velum. [2] [3][4]The maxillary nerve branch of the trigeminal nerve (V) supplies sensory innervation to the palate.

The hard palate is formed before birth. If the fusion is not complete, it is called a cleft palate. As the roof of the mouth was once considered the seat of the sense of taste, palate can also refer to this sense itself, as in the phrase "a discriminating palate". By further extension, the flavor of a food (particularly beer or wine) may be called its palate, as when a wine is said to have an oaky palate.

PALATE (Lat. palatum, possibly from the root of pascere, to feed), the roof of the mouth in man and vertebrate animals. The palate is divided into two parts, the anterior bony "hard palate" (see Mouth), and the posterior fleshy "soft palate" (see Pharynx). For the malformation consisting in a longitudinal fissure in the roof of the mouth, see Cleft Palate.
