Peripheral Neuropathy Flashcards
what are symptoms experienced when large motor fibres are affected?
weakness, unsteadiness
decreased power
absent reflexes
normal sensation
what are symptoms experienced when large sensory fibres are affected?
numbness, paraethethia
decreased vibration sensation
normal power
what are symptoms experiences when small fibres are affected?
pain and dysethia
normal power
decreased pin prick and temperature sensation
present reflexes
what is the treatment for demyelinating inflammatory neuropathy?
Azathrioprine
mycophenalate
cyclophosphamide
what is the treatment for axonal vasculitis?
IV methy-prednisalone + cyclophosphamide
what are the symptoms experiences when autonomic system is affected?
dizziness (dec. BP), impotence, gastroparesis
normal power
normal sensation
normal reflexes
what is the motor flexor reflex?
contraction of flexor + relaxation of extensors
what is the role of the motor flexor reflex?
enhances postural support during withdrawal of a foot from painful stimulus
where does the descending spinal tract originate from?
cerebral cortex + brain stem
what are the 2 pathways of the descending spinal tract?
lateral - skilled movements
ventro-medial - posture + locomotion
where is the location of the cortico-spinal tract motor aspect?
BA4 + BA6
where is the location of the cortico-spinal tract sensory aspect?
parietal cortex
where do the axons terminate in the cortico-spinal tract?
ventral horn
where are the cells bodies in the ventro-medial pathway found?
optic tectum
what is the name of the 3 ventro-medial pathways?
pontine
medullary
retrulospinal
