- frontal lobe
- parietal lobe
- temporal lobe
- occipital lobe

What are the three parts of the brain stem?
- midbrain
- pons
- medulla oblongata
grey matter
unmyelinated axons
white matter
myelinated axons
What are the three layers that surround the cns starting with the outermost layer?
- dura mater
- arachnoid mater
- pia mater
What are the functions of the frontal lobe?
- concentration
- decision making
- planning
- skeletal muscles
- verbal communication
central sulcus
separates frontal lobe from parietal lobe

separates frontal lobe from parietal lobe
somatesthetic sensation
- ability to feel or perceive
- ex. pinching
somatesthetic sensation
- ability to feel or perceive
- ex. pinching
What are the functions of the occipital lobe?
- correlating new images with previous images
- eye movement
- perception and understanding of visual images (happy or sad)
- vision

What is hemispheric lateralization due to?
the separation of fibers
How does the corpus callosum play into hemispheric lateralization?
allows dominant side to take over motor function and decision making
What does the non-dominant hemisphere specialize in?
non-verbal functions (emotions, experiences, intuitive thinking)
right hemisphere
- aRt
- compressions of patterns and part/whole relationships
- nonverbal experiences (how it felt or looked)
- music composition but NOT analysis
- recognition of people based on facial features
- visuospatial tasks (feng shui)

Broca’s area
- movements of structures for speech production
Where is Broca’s area located?
- frontal lobe
- left side of brain
Where is Wernicke’s area located?
temporal lobe
Where is Wernicke’s area located?
temporal lobe
expressive/Broca’s aphasia
- inability or limited speech
- right sided weakness, paralysis
- able to understand, aware of inability
