The trigeminal ganglion and its branches represented here as 1st division, 2nd division, and 3rd division. The Trigeminal Cave houses this ganglion.
|Latin||cavum Meckeli, cavum trigeminale|
The trigeminal cave is formed by two layers of dura mater which are part of an evagination of the tentorium cerebelli near the apex of the petrous part of the temporal bone. It envelops the trigeminal ganglion. It is bounded by the dura overlying four structures:
- The cerebellar tentorium superolaterally
- The lateral wall of the cavernous sinus superomedially
- The clivus medially
- The posterior petrous face inferolaterally
