Gyri
Elevated ridges
Sulci
Shallow grooves
Fissures
Deeper grooves between L and R
What are the 5 lobes formed by
Deeper sulci
3 regions of cerebral hemisphere
Cortex
White matter
Basal nuclei
Cerebral cortex
Only gray matter
Place for perception, communication, memory, understanding, initiating movement
Cerebral white matter
Deep to cortex
Provides communication within cerebrum
Corpus callosum connects hemisphere
