neural 1; defects and TBI Flashcards
concussion
both hemispheres are involved
blackout ie interruption of brain fx
scattered =
diffuse
coup injury
one hemisphere is involved
local =
focal
inflammation of the meninges bacterial or viral vaccines for bac because its 60% fatal viral is self-limiting with sx tx meningismus
meningitis
diffuse axonal injury
damage to axons
vegetative state
congenital defects include
hydrocephalus
spina bifida
cerebral palsy
crude support for movement; big bulky muscles
extrapyramidal pathway
spina bifida
most common neural tube defect in US
idiopathic
varies from occulta to myelomeningocele
surgery that relieves fluid pressure in brain
shunt
focal =
local
countrecoup injury
both hemispheres are involved
cerebral palsy
progressive
permanent motor/ coordination dysfunction until affects cerebrum
crossing of the fibers of the corticospinal tracts from on side of the central nervous system to the other near the medulla and spinal cord
pyramidal decussion
simple crack in skull
simple/ linear
neuromuscular unit =
motor unit
most common neural tube defect in US
idiopathic
varies from occulta to meningocele to myelomeningocele
spina bifida
mildest form
most common form of spina bifida
small gap in vertebrae
spina bifida occulta
motor unit =
neuromuscular unit
myelomeningocele
most sever form of spina bifida
spinal canal remains open along several vertebrae in the lower back
meninges, spinal cord, spinal nerves, and CSF protrude through this large opening at birth
pyramidal decussion
crossing of the fibers of the corticospinal tracts from one side of the central nervous system to the other near the medulla and spinal cord
