Brain anatomy in 3D:
brain and skull section

The brain in its position within the sectioned skull, with meninges, cerebral vessels and cranial nerves.

The brain is covered by three meninges: the dura mater, which lines the skull and forms the dural venous sinuses, the arachnoid mater and the pia mater. The subarachnoid space between the arachnoid and pia contains cerebrospinal fluid and the main cerebral arteries.
