What are the parts of palatine bone?
The palatine bone has a horizontal and vertical plate as well as a pyramidal process (or pyramid-shaped portion). 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.
Where is the 2 palatine bones located?
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.)
Where is the perpendicular plate?
The perpendicular plate is a thin lamina which runs vertically from the cribriform plate. Inferiorly it attaches to the septal cartilage of the nose and hereby forms part of the nasal septum.
Which of the following bones form part of the bony palate?
Inside the mouth, the palatine processes of the maxilla bones, along with the horizontal plates of the right and left palatine bones, join together to form the hard palate.
What is cribriform plate?
The cribriform plate is the portion of the ethmoid bone that forms the roof of the nasal cavity. This narrow bony structure contains deep grooves known as olfactory fossa, which supports the olfactory bulb.
What bone contains the perpendicular plate?
The ethmoid bone
The ethmoid bone consists of the cribriform plate, two ethmoid labyrinths, and the perpendicular plate.
What does perpendicular plate mean?
Medical Definition of perpendicular plate 1 : a flattened bony lamina of the ethmoid bone that is the largest bony part assisting in forming the nasal septum. 2 : a long thin vertical bony plate forming part of the palatine bone — compare horizontal plate.
What bone forms the roof of the mouth?
The incisive, maxillary and palatine bones form the roof of the mouth.
What two bones form the hard palate?
The hard palate comprises about two-thirds of the total palate surface area, and its underlying bony structure consists of the palatine processes of the maxilla and the horizontal plates of the palatine bones.
What bone is the cribriform plate part of?
the ethmoid bone
The cribriform plate of the ethmoid bone separates the caudal nasal cavity from the brain.
Why is the cribriform plate important?
This bone, the cribriform plate, transmits the olfactory nerves that carry the sense of smell.
