2. molars |
|
|
What is the route of the Zygomatic nerve?
|
Enters the orbit via inferior orbital fissure
|
|
|
What are the 2 branches of the zygomatic nerve?
|
1. Zygomaticofacial

|
|
What is innervated by the
-Zygofacial n -Zytotempo n |
ZF = skin over cheek prominence
ZT = skin of temporal region |
|
|

|
foramen of the same names
|
|
|
What are the 2 palatine nerves?
|
Greater and lesser
|
|
|
What does the greater palatine innervate?
|
Gingiva and mucosa of hard palate
|
|
|
What does the lesser palatine inervate?
|
Soft palate, uvula, tonsil
|
|
|
How do the palatine nerves exit the skull?
|
Via the pterygopalatine canal
|
|
|
How do the greater/lesser palatine nerves exit the pterygopalatine fissure?
|
Via the greater/lesser palatine foramina
|
|
|
What does the meningeal nerve branch of the maxillary nerve innervate?
|
Dura mater
|
|
|
How does the meningeal nerve get to the dura mater?
|
By traveling with the middle meningeal artery.
|
|
|
What is special about the Zygomaticotemporal nerve?
|
It carries postganglionic parasympathetic secretomotor fibers of CN VII from the pterygopalatine ganglion to the lacrimal nerve.
|
|
|
What is special about the palatine nerves?
|
They carry taste fibers that pass thru the pterygopalatine ganglia and travel w/ the nerve of pterygoid canal and greater petrosal nerve to eventually join CN VII
|
|
|
Where are the cell bodies of the nerves we were just discussing located?
|
In the geniculate ganglion.
