Brain Flashcards
How many areas does the brain have? What are they?
1- Cerebrum
2- Diencephalon
3- Brain stem
4- Cerebellum
What is the PONS?
The vital center
The vital center of the brain controls what?
Breathing and some regulation of the heartrate (HR) and blood pressure (BP)
The cerebral cortex is made mostly of up of white or grey matter?
Grey matter
The cerebrum is primarily made up of white or grey matter?
White
What is the purpose of the fissures of the brain?
For CSF to pass through
What is brain sag?
When there is pressure on the cerebellum due to the loss of CSF - can kill you
What are the 3 fissures of the brain?
Central, lateral and longitudinal
What causes an ischemic stroke?
A blockage of sorts preventing blood flow to a section of the brain. It’s oftentimes a blood clot
What happens to the brain during a hemorrhagic stroke?
A brain bleed causes a lack of oxygen to a section of the brain and the blood causes pressure to build up inside the cranium further damaging the brain - extremely dangerous
What is the difference between a transient ischemic attack (TIA) and an ischemic stroke?
TIA: temporary and doesn’t cause damage. Does produce symptoms and can be a precursor to a stroke. Reduction in blood flow to an area of the brain, often causes by plaques in blood vessels
Ischemic stroke: blockage to the brain, oftentimes by a blood clot. Persists and requires treatment. Can cause lifelong impairment and even death
What does the frontal lobe do?
Manages behavior, personality and motor control.
Where is the cerebral cortex?
The outmost portion of the cerebrum
The cerebral cortex is made up of white or grey matter?
Grey matter
The parietal section of the brain has what functions?
Somatosensory (muscular and the ability to feel where you are in space), gustation
