This document provides a review of Neuroanatomy Lab 3 which covers the cerebral vasculature, meninges, hemispheres, and includes review questions. It discusses the three layers of the meninges (dura mater, arachnoid mater, pia mater), the arteries that supply the brain including the internal carotid and vertebral arteries, and key structures like the cingulate gyrus and central sulcus. Diagrams are included from the Digital Anatomist Project to illustrate these structures.
