[4], There are numerous variations amongst mammals, amphibians and other species. The Palatine bone can be affected by infection, facial fractures, trauma and cancer. Together with the maxillae, they comprise the hard palate. The horizontal plate makes up the roof of the mouth, and the rear portion of the oral cavity, just behind the nasal cavity; its front end is serrated and its back end is smoother.

They contribute to the walls of three cavities: the floor and lateral walls of the nasal cavity, the roof of the mouth, and the floor of the orbits. In anatomy, the palatine bones (/ˈpælətaɪn/[1][2]) are two irregular bones of the facial skeleton in many animal species, located above the uvula in the throat.

The palatine bones are situated at the back of the nasal cavity between the maxilla and the pterygoid process of the sphenoid bone. Roof, floor, and lateral wall of left nasal cavity. Articulation of left palatine bone with maxilla. Individual palatine bones are almost never found in an isolated, intact state; they generally accompany the maxillae and sphenoid, to which they are tightly bound. Various birth defects can also affect this bone and cause a defect in the face of an individual. It forms part of the nasal cavity, oral cavity, and orbit of the eye. There are two important foramina in the palatine bones that transmit nerves and blood vessels to this region: the greater and lesser palatine. (Horizontal part of palatine bone visible at bottom. It participates in building the three cavities within the skull ; the oral cavity , nasal cavity and the orbits . The palatine bones are situated at the back of the nasal cavity between the maxilla and the pterygoid process of the sphenoid bone. Individual palatine bones are almost never found in an isolated, intact state; they generally accompany the maxillae and sphenoid, to which they are tightly bound.

Each of these bones is known as a Palatine Bone, commonly referred to as Palatum.

Both foramina are openings of the pterygopalatine canal that carries the descending palatine nerves and blood vessels from the pterygopalatine fossa to the palate. This location leaves the palatine bone lying at the back of the nasal cavity. For other uses, see, Sagittal section of skull. It is one of the many paired bones in the human body. tine bone. Palatine bone anatomy is usually split into two subcategories – the perpendicular plate and the horizontal plate; remember that these are paired bones – left and right. 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. ), Permanent teeth of upper dental arch, seen from below. Each palatine bone somewhat resembles the letter L, and consists of a horizontal plate, a perpendicular plate, and three projecting processes — the pyramidal process, which is directed backward and lateral from the junction of the two parts, and the orbital and sphenoidal processes, which surmount the vertical part, and are separated by a deep notch, the sphenopalatine notch.

In addition to these two, palatines articulate with the vomer, inferior nasal conchae, ethmoid, and with each other. The palatine bone has a horizontal and vertical plate as well as a pyramidal process (or pyramid-shaped portion). They contribute to the walls of three cavities: the floor and lateral walls of the nasal cavity, the roof of the mouth, and the floor of the orbits. The lower surface of the bone may bear several teeth, forming a second row behind those of the maxilla; in many cases, these are actually larger than the maxillary teeth. The two plates form the posterior part of the hard palate and the floor of the nasal cavity; anteriorly, they join with the maxillae. Palatine bones … In humans, this bone is found between the maxilla, or upper jawbone, and the sphenoid bone, located at the base of the skull. The below image shows labeled palatine bones positioned as mirror images of each other. The seven bones which articulate to form the orbit. The palatine bone has a horizontal and vertical plate as well as a pyramidal process (or pyramid-shaped portion). A parallel development has occurred to varying degrees in many living reptiles, reaching its greatest extent in crocodilians. [3], The sphenopalatine foramen is the opening between the sphenoid bone and orbital processes of the palatine bone; it opens into the nasal cavity and gives passage to branches from the pterygopalatine ganglion and the sphenopalatine artery from the maxillary artery. This forms the rear of the hard palate, separating the oral and nasal cavities, and making it easier to breathe while eating. The palatine bone is one of the bones of the face. The small, delicate, L-shaped palatine bones form the rear of the hard palate and part of the wall and floor of the nasal cavity.

Imaging the soft tissue of the nose between them.

The palatine bones are situated at the back of the nasal cavity between the maxilla and the pterygoid process of the sphenoid bone.
