What is maxilla palatine?
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. Palatine process of maxilla.
What is the function of the Palatine process?
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) |
Where is palatine located?
nasal cavity
Structure. The palatine bones are situated at the back of the nasal cavity between the maxilla and the pterygoid process of the sphenoid bone. 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.
What is maxilla process?
Each maxilla has four processes (frontal, zygomatic, alveolar, and palatine) and helps form the orbit, roof of the mouth, and the lateral walls of the nasal cavity.
What type of bone is the palatine?
irregular facial bone
Definition. The palatine bone or os palatinum is a paired, flat, irregular facial bone. It forms part of the nasal cavity, oral cavity, and orbit of the eye. Composed of two plates, each bone sits between processes of the right or left maxilla bone and the single sphenoid bone.
Is palatine a facial bone?
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 in biology?
Definition. The palatine bone or os palatinum is a paired, flat, irregular facial bone. It forms part of the nasal cavity, oral cavity, and orbit of the eye. Composed of two plates, each bone sits between processes of the right or left maxilla bone and the single sphenoid bone.
Is the hard palate a bone?
The hard palate is made up of four cranial bones: the paired maxillae and the paired palatine bones. The maxillae are situated anteriorly and cover the majority of the area between the two sides of the dental arch. Medially, the maxillae articulate to one another via the anterior median palatine suture.
Is palate a bone?
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.
Why does my maxillary hurt?
Inflammation in your nasal cavities can cause sinusitis. This tends to happen if you’ve had a cold, but allergies and other medical conditions can also contribute to sinusitis. If the sinus cavities behind your cheeks, known as the maxillary sinuses, are inflamed, you might feel pain in one or both sides of your jaw.
What kind of bone is maxilla?
The answer to the question, “What type of bone is the maxilla bone?” is simple – it is an irregular facial bone. You can refer to the maxilla bone as a single unit or as two paired but fused bones.
Which condition is a congenital defect of the palatine bones?
A cleft lip is a separation of the two sides of the lip, usually involving the bones of the upper jaw, upper gum, or both. A cleft palate is an opening in the roof of the mouth in which the two sides of the palate did not fuse or join together properly.
