Exploration of the meninges and brain in situ
Posterior view of cranial meninges
On the right the calvaria and layers of the scalp are shown in relation to the dura. On the left the dura has been cut away to reveal the cerebral hemisphere and cerebellum covered with the arachnoid membrane. The confluence of the sinuses (23) is shown.
