brain and cord stuff Flashcards
what type of reflexes would be expected in an upper motor neurone lesion
hyper reflexia
are fasciculation’s seen in upper or lower motor neurone lesion
LMN
in central cord syndrome what is seen
distal upper limb weakness and cape like spinothalamic loss
normal volume of CSF
120-150ml
where is CSF produced
choroid plexus
where is CSF absorbed
arachnoid granulations
in CSF what should glucose levels be
> 2.2
what is hydrocephalus
increased CSF in brain
what is non- communicating hydrocephalus
obstruction to CSF occurring within ventricular system
what is communicating hydrocephalus
obstruction to CSF flow outside of ventricular system eg, subarachnoid space or arachnoid granules
what is hydrocephalus ex vacuo
increase in csf vol due to decreased brain vol eg Alzheimers
what would glucose levels look like in lumbar puncture in bacterial meningitis
decreased glucose and abundant polymorphs eg neutrophils
what is likely organism in bacterial meningitis in neonates
e.coli
what is likely organism in bacterial meningitis in adolescents
neisseria meningitides
what is likely organism in bacterial meningitis in older people
listeria monocytogenes
