Palatine bone
Updates to Article Attributes
Body
was changed:
The palatine bones are paired L-shaped bones joined at the midline. They form the hard palate with the maxillary bones. They also form part of the nasal cavity.
Gross anatomy
They are located at the back of the nasal cavity, between the maxilla and sphenoid bones. Each bone consists of a horizontal and perpendicular plate forming an L-shape. There are three processes, the pyramidal, orbital and sphenoidal.
They contribute to the formation of the hard palate, the nasal cavity, the orbital floor and the pterygopalatine fossa.
Articulations
- with the palatine process of the maxilla anteriorly forming the transverse palatine suture
- with its opposite counterpart in the midline
- with the vomer
- with the inferior concha
- with both the body and the medial pterygoid plate of the sphenoid
- with the ethmoid
Attachments
- tensor palati to the posterior border of the horizontal plate
- muscle of the uvula to the nasal spine of the horizontal plate
- superficial head of the medial pterygoid muscle to the pyramidal process
Foramina
-
thegreater palatine foramen- transmits the greater palatine vessels and nerve from the pterygopalatine fossa to the oral cavity
. It is - formed by the greater palatine groove and converted to a canal by articulation with the maxilla
- transmits the greater palatine vessels and nerve from the pterygopalatine fossa to the oral cavity
-
thelesser palatine foramentransmit- transmits the lesser palatine nerves and vessels
-
thesSphenopalatinephenopalatine foramen- formed by the sphenopalatine notch of the palatine bone and articular with the body of the sphenoid bone
. It - connects the pterygopalatine fossa to the nasal cavity and transmits the sphenopalatine artery and vein, nasopalatine nerve and posterior superior nasal nerves
- formed by the sphenopalatine notch of the palatine bone and articular with the body of the sphenoid bone
Ossification
- intramembranous ossification, appears eighth week in utero
- at birth the horizontal and perpendicular plates are of equal size
