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
