Thrombotic Ischemic stroke
-
Type of ischemic stroke that results from blood clot from somewhere else in the body that trevels to the brain. Once in the brain it travels to a vessel small enough to block it's passage.
Embolic Ischemic stroke
-
____ builds up eventuall causing a rupture and ____ come by and stick causing a blockage.
-
Type of stroke caused by weakened vessels that rupture and bleed into surrounding brain.
Hemorrhagic stroke
-

-
Two types of hemorrhagic stroke.
- Subarachnoid
- Intracerebral
-
Type of hemorrhagic stroke caused by rupture of atery.
Subarachnoid hemorrhage
-
Type of hemorragic stroke that results in blood filling the space surrounding the brain rather than insdie of it (b/w brain and skull).
Subarachnoid hemorrhage
-
With subarachnoid hemorrhage, it is usually caused by ____ ____ (ballooning of vessel, over time it may rupture)
Ruptured aneurism
-
With subarachnoid hemorrhage, there is a sudden increase in ____ w/in the brain and can cause damage to ____ ____ surrouund the blood.
-
Type of hemorrhagic stroke that occurs when a blood vessel w/in brain bursts (deep in tissue of brain)
Intracerebral hemorrhage

-
Three components of the brain.
- Cerebrum
- Cerebellum
- Brainstem
-
Largest, most advanced portion of brain - R/L hemisphere (temporal, frontal, occipital, parietal)
Cerebrum
-
Second largest portion of brain. At back of brain - smooth, coordinated movement.
Cerebellum
-
At back of brain and base. Autonomic function, affects/controls respiratory rate, BP, HR, wakefullness, articulation of speech.
Brainstem
-
A region of the brain concerned with the production of speech, located in the cortex of the dominant frontal lobe.
Broca's area at front of brain
-
Region of the brain concerned with the comprehension of language.
Wernicke's area
