1. Parts of the brain

2. Four Major Regions Cerebral Hemispheres Diencephalon Brain Stem
Cerebellum

3. Cerebrum
Contains cerebral cortex, hippocampus, basal ganglia, and olfactory bulb
Superior most region of CNS
Controls all voluntary actions in body
Divided into lobes

4. Gray and White Matter of Brain
Outer region- cerebral cortex- gray matter- cell bodies
Inner region- white matter- composed of bundles of nerve fibers
Gray matter “islands”-basal nuclei- within white matter
Regulate voluntary motor activities

5. Cerebrum
Corpus Callosum- connects cerebral hemispheres (large fiber tract)
Gyri-ridges of tissues
Sulci-shallow grooves separating gyri
Fissures-deeper groves
Lobes- divide cerebral hemispheres
Named for bone that lie over them

6. Parietal Lobe Somatic sensory area
Recognize pain, coldness, or light touch

7. Occipital Lobe
Visual area located in posterior region

8. Temporal Lobe
Auditory area located here

9. Gray and White Matter of Brain
Outer region- cerebral cortex- gray matter- cell bodies
Inner region- white matter- composed of bundles of nerve fibers
Gray matter “islands”-basal nuclei- within white matter
Regulate voluntary motor activities

10. Frontal Lobe Primary motor area
Allows us to consciously move our skeletal muscles

11. Broca's area Specialized area involved in our ability to speak
(located in frontal lobe)

12. Speech area
Located at junction of temporal, parietal, and occipital lobe.
Sound out words

13. Additional Info Higher intellectual reasoning Frontal lobe
Complex memories
Temporal and frontal lobes
Language comprehension
