What is palatine in anatomy?
Making up a portion of the nasal cavity and palate, the palatine bone is a paired, L-shaped facial bone. It forms a part of the underside of the skull, and lies between the maxilla bone (the fixed, upper bone of the jaw) and the sphenoid bone (whose wings help form the base of the eye sockets and base of the skull).
What is Palatine process?
Medical Definition of palatine process : a process of the maxilla that projects medially, articulates posteriorly with the palatine bone, and forms with the corresponding process on the other side the anterior three-fourths of the hard palate. — called also palatal process.
What is the function of the Palatine process of the maxilla?
The palatine process of the maxilla bone and the horizontal plate of the palatine bone provide the components of the nasal cavity floor. The os palatinum is also an attachment point for facial muscles.
What are the parts of palatine bone?
Palatine bone
| Parts | Horizontal plate, perpendicular plate, pyramidal process, orbital process, sphenoidal process |
|---|---|
| Function | Participates in the formation of the: Nasal cavity Hard palate Orbit (floor) Pterygopalatine fossa Pterygoid fossa (inferior part) |
How are palatine bones formed?
Each bone consists of a horizontal and perpendicular plate forming an L-shape. There are three processes, the pyramidal, orbital and sphenoidal. They make structural contributions to the hard palate, nasal cavity, orbital floor and pterygopalatine fossa.
Where is the ethmoid bone?
The ethmoid bone is an unpaired cranial bone that is a significant component of the upper nasal cavity and the nasal septum. The ethmoid bone also constitutes the medial orbit wall.
What type of bone is palatine?
Anatomical terms of bone In anatomy, the palatine bones (/ˈpælətaɪn/) are two irregular bones of the facial skeleton in many animal species, located above the uvula in the throat. Together with the maxillae, they comprise the hard palate. (Palate is derived from the Latin palatum.)
What sutures does the palatine process of the maxilla form?
The palatine process (Processus palatinus) of the maxilla is a strong bony blade that arises perpendiculary from the nasal surface of the maxilla, near its ventral border; it unites with the palatine process of the opposite maxilla on the median plane through the palatine suture (Sutura palatina).

Where are the palatine bone located?
nasal cavity
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. 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.
Why is the ethmoid bone important?
The ethmoid bone is a cube-shaped bone located in the center of the skull between the eyes. It helps form the walls of the eye socket, or orbital cavity, as well as the roof, sides, and interior of the nasal cavity.
