-Parietal lobe
-Occipital lobe
-Temporal lobe
-Insula
Diencephalon
Between the cerebrum and the midbrain
-Contains the thalamus and hypothalamus
Cerebellum
Posterior and inferior to the cerebrum, it contains the most neurons
-Monitors body movements
-Balance, coordination, posture
-Evaluates sensory input
-Helps muscle groups work together
Parts of the brain stem
-Midbrain
-Pons
-Medulla oblongata
Gyri

Longitudinal fissure
Deep groove that divides cerebrum into left and right
Corpus callosum
Connects left and right hemisphere
Where is gray matter found
-On the surface of the brain
-In patches in the white matter
-Posterior and anterior horns of the spinal cord
Where is white matter found
-Underneath the cerebral cortex
-Surrounding the gray matter in the spinal cord
Two layers of Dura Mater
-Periosteal layer (outer)
-Meningeal layer (inner)
Dural sinuses
Collects blood that needs to be returned to the heart
