anoxia total depletion in the level of O2 although there is
adequate blood flow
hypoxia decrease in O2 levels despite adequate blood
flow
necrotic pathway cell energy failure and rapid cytoskeletal
breakdown
apoptotic pathway programmed cell death
primary brain injury An injury to the brain and its associated structures
that is a direct result of impact to the head.
Secondary brain injury The "after effects" of the primary injury; includes
abnormal processes such as cerebral edema,
increased intracranial pressure, cerebral ischemia
and hypoxia, and infection; onset is often delayed
following the primary brain injury.
, mass effect a phenomenon in which a focal lesion or
contusion causes surrounding area of the brain
tissue or brain structures to be compressed and
injured due to the degree of space that leaking
blood, CSF, or edema take up within the restricted
skull space
saccular aneurysm Bulge on side of vessel- accounts for a large
majority of cerebral aneurysms
fusiform aneurysm dilation of the entire circumference of the artery
cerebral vasospasm when the blood vessels in the brain narrow,
thereby reducing blood flow to the brain and
subsequent death of brain tissue
Anterior Communicating Artery connects Right and Left ACA
Middle cerebral Artery supplies the parietal and temporal lobes
Posterior Communicating Artery helps connect blood from the anterior and
posterior circulation
Posterior Cerebral Artery supplies the occipital lobe, thalamus, and
midbrain
Basilar Artery and Vertebral Artery supply blood to the brain stem and cerebellum
Wernicke's area language comprehension (temporal lobe)
Broca's area speech production (frontal lobe)
