The palate (/ ˈ p æ l ɪ t /) 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 separated.
The soft palate (also known as the velum, palatal velum, or muscular palate) is, in mammals, the soft tissue constituting the back of the roof of the mouth. The soft palate is part of the palate of the mouth; the other part is the hard palate .
The hard palate is a thin horizontal bony plate made up of two bones of the facial skeleton, located in the roof of the mouth. The bones are the palatine process of the maxilla and the horizontal plate of palatine bone. The hard palate spans the alveolar arch formed by the alveolar process that holds the upper teeth (when these are developed).
A smaller opening nearby, the lesser palatine foramen, transmits the lesser palatine nerve and blood vessels to the soft palate and tonsils. Both foramina are openings of the pterygopalatine canal that carries the descending palatine nerves and blood vessels from the pterygopalatine fossa to the palate. [3]
In human anatomy of the mouth, the palatine process of maxilla (palatal process), is a thick, horizontal process of the maxilla.It forms the anterior three quarters of the hard palate, the horizontal plate of the palatine bone making up the rest.
The greater palatine foramen is, along with the lesser palatine foramen, one of two foramina (holes) in each of the left and right palatine bones which form the posterior roof of the human mouth, known as the palate. It is sometimes known as the major palatine foramen.
the pterygopalatine nerves to the hard palate. [2] the nasopalatine nerves from the floor of the nasal cavity. [3] the sopalatine branches of the infratrochlear nerve, a branch of the ophthalmic nerve (V1), itself a branch of the trigeminal nerve. [4] the sphenopalatine artery supplying the mucous membrane covering the hard palate of the mouth. [3]
It emerges upon the hard palate through the greater palatine foramen. It then passes forward in a groove in the hard palate, nearly as far as the incisor teeth. While in the pterygopalatine canal , it gives off lateral posterior inferior nasal branches , which enter the nasal cavity through openings in the palatine bone , and ramify over the ...
