midterm pt.2 Flashcards
flaccidity
motor loss
paresis
weakness
anesthesia
sensory loss
paresthesia
sensory impairment
dysesthesia
pain
1st degree, compression of nerve, no structural damage, local demyelination, loss of motor function but sensory & autonomic fibers unaffected, prognosis = good
neuropraxia
2nd degree, prolonged severe compression, degeneration, sensory, motor & autonomic losses, prognosis = good, endoneurial tube intact
axonotmesis
3rd-5th degree, severance of part of/ all of nerve trunk, difficulty regenerating, sensory, motor & autonomic losses, surgical repair, prognosis = bad
neurotmesis
inflammation of a nerve, constant dull pain
neuritis
pain syndrome, abnormal sympathetic reflex, arterial spasm
reflex sympathetic dystrophy (RSD)
hydro CI for RSD
tissue dystrophy / lack of vasomotor control
tumor composed of nerve cells
neuroma
nerve pain, “lighting like”, throbbing
neuralgia
AKA tic douloureux (CNV)
trigeminal neuralgia
-opthlamic, maxillary, mandibular
causes of intercostal neuralgia
trauma, diabetes, shingles
severe pain syndrome, associated with traumatic injury (gunshot wound)
causalgia
peripheral nerves ability to regenerate if axon is damaged & cell body intact
Wallerian degeneration
the median & radial nerve originate from…
C5-T1
the ulnar nerve originates from…
C8-T1
complete radial nerve lesion presentation
wrist drop
continuation of the posterior cord of the brachial plexus (C5-T1)
radial nerve
complete ulnar nerve lesion presentation
claw hand deformity, bishops/ pope hand
originates from the medial cord of the brachial plexus (C8-T1)
ulnar nerve
site of compression for the ulnar nerve
tunnel of Guyon
