HOSA Pathophysiology Nervous System
with sense
Cerebrovascular accident (stroke) - brain is damaged by a sudden disruption in the flow of blood to a
part of the brain {embolic} or by bleeding inside the head{hemorraghic}
aphasia - Disturbance in language comprehension or production, often as a result of a stroke.
dysphasia - Difficult speech
paralysis - Absence of strength secondary to nervous impairment.
hemiparesis - partial paralysis of the right or left half of the body
diplopia - Double vision.
Transient Ischemic Attack (mini-stroke) - temporary episodes with a duration of less than 24 hours of
impaired neurologic functioning caused by an inadequate flow of blood to a portion of the brain
ulcer - A deep loss of skin surface that may extend into the dermis; may cause periodic bleeding and the
formation of scars.
concussion - A loss of function, either partial or complete, as resulting from a blow or fall (for instance)
contusion - A bruise
contrecoup - also known as a counter blow, is an injury that occurs beneath the skull opposite to the
area of impact
epidural hematoma - collection of blood that forms between the skull and the dura mater
, dura mater - Outermost layer of the meninges
subdural hematoma - blood collects btween the dura mater and the arachnoid membrane
arachnoid membrane - middle layer of the three membranes (meninges) that surround the brain and
spinal cord
craniotomy - Incision into the skull
cerebral concussion - Temporary brain dysfunction (brief loss of consciousness) after injury, usually
clearing within 24 hours
cerebral contusion - Bruising of brain tissue as a result of direct trauma to the head; neurologic deficits
persist longer than 24 hours
Depressed skull fracture - -bone pressed inward into the brain tissue to at least the thickness of the skull;
skull depressed : may cause bruising or tearing of dura and lead to menengitis or seizures, -skull
depressed : may cause bruising or tearing of dura and lead to menengitis or seizure
hemiplegia - paralysis of one side of the body
Battle's signs - Bruising behind the ears (over the mastoid process); a very late sign of skull fracture.
Raccon eyes - Basal skull fracture
nuchal rigidity - neck stiffness
paraplegia - Paralysis from the waist down
