Dura mater

Question 18

Branches of V2 (maxillary)

How does the meningeal nerve get to the dura mater?

Answer 18

By traveling with the middle meningeal artery.

Question 19

Branches of V2 (maxillary)

What is special about the Zygomaticotemporal nerve?

Answer 19

It carries postganglionic parasympathetic secretomotor fibers of CN VII from the pterygopalatine ganglion to the lacrimal nerve.

Question 20

Branches of V2 (maxillary)

What is special about the palatine nerves?

Answer 20

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

Question 21

Branches of V2 (maxillary)

Answer 21

In the geniculate ganglion.
