====== Meningohypophyseal trunk ======

The meningohypophyseal trunk, also known as the posterior trunk, is a branch of the C4 segment of the [[internal carotid artery]]. It is, as opposed to the [[inferolateral trunk]], almost always identified at dissection and usually visualised on good quality angiography. 

====Branches====

[[Inferior hypophyseal artery]]: to the pituitary gland, contributing to the "inferior hypophyseal arterial circle"

Marginal [[tentorial artery]]: to the meninges of the [[tentorium]].

Tentorial basal branch

Tentorial marginal branch

Meningeal branch - helps supply blood to the meninges of the anterior cranial fossa

Clivus branches - tiny branches that supply the clivus

Inferior hypophyseal artery

Capsular branches - supplies wall of cavernous sinus

Branches of the inferolateral trunk:

Branches to trigeminal ganglion - provide blood to trigeminal ganglion

Artery of the foramen rotundum

Branches to nerves
