Exploration of the meninges and brain in situ
Relation of posterior cerebral artery to tentorium
The specimen is viewed from behind and laterally. The left half of the brain stem has been cut across in the subthalamic region. Temporal branches of the posterior cerebral artery remain in situ above the tentorium after the temporal and occipital lobes of the hemisphere have been removed. In many places the arachnoid and pia mater also are intact.

3 . Internal carotid artery (within chiasmatic cistern)
4 . Middle cranial fossa

6 . Oculomotor nerve (llI)
7 . Choroidal artery (anterior)
8 . Posterior cerebral artery
