There are two important foramina in the palatine bones that transmit nerves and blood vessels to this region: the greater and lesser palatine. The larger greater palatine foramen is located in the posterolateral region of each of the palatine bones, usually at the apex of the maxillary third molar. The greater palatine foramen transmits the ...
The hard palate is formed by the palatine process of the maxilla and horizontal plate of palatine bone.It forms a partition between the nasal passages and the mouth.On the anterior portion of the hard palate are the plicae, irregular ridges in the mucous membrane that help hold food while the teeth are biting into it while also facilitating the movement of food backward towards the larynx once ...
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. It is the most important bone in the midface. It provides structural support for the ...
It is sometimes known as the major palatine foramen. The greater palatine foramen functions primarily for the transmission of the descending palatine vessels and greater palatine nerve ; running anteriorly (forward) and medially (towards the center-line) from it is a groove, for the same vessels and nerve.
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.
It includes epithelium and lamina propria, but attaches directly to the periosteum of underlying bone without the usual submucosa. It consists of loose fatty or glandular tissues; with blood vessels & nerve fibres that supply the mucosa. It can be found in the midline of the hard palate, the palatine raphe, among other places.

posterior: root of the pterygoid process and adjoining anterior surface of the greater wing of sphenoid bone; medial: perpendicular plate of the palatine bone and its orbital and sphenoidal processes; lateral: pterygomaxillary fissure; inferior: part of the floor is formed by the pyramidal process of the palatine bone.
The greater palatine canal starts on the inferior aspect of the pterygopalatine fossa. It goes through the maxilla and palatine bones to reach the palate, ending at the greater palatine foramen. From this canal, accessory canals branch off; these are known as the lesser palatine canals .
