Introduction to the Neurological Examination 1 Flashcards
Basal ganglia and cerebellar responsibility
Maintain muscle tone and control movements when walking
Coordinate motor activity, maintain equilibirium, posture
Corticospinal
Carries inhibitory tone
graphesthesia
Sterognosis
Tactile extension
Can you tell the number
Can you ID object in hand
Can you only feel on one side
CN1 test and anosmia
Smoking could impair
Don’t use noxious
How to chekc visuakl acuity
Snellen chart @ 14 inch or ideal at 20 feet
Best vision at line patient can read 1/2
Use best corrected
Bitemporal hemmianopsia
Lesion of optic tract
Lose lateral fields of both eyes
Eye opening and closing
Opening - 3
Closing - 7
Anisocoria
Different sized pupikls
Pupillary light reflex
Affarent is CN 2
Efferent is CN 3
Both eyes Should constrict when light applied
Swiniging flashlight
optic N damage
Affected pupil will respond less vigorously from indirect response
If left is lesion, when shine in right, normal…when shine in left, left and right both constrict less than at right…basically dilates from constricted state
Marcus Gunn Pupil
Swinging flashlight test
Most commonly from optic neuritis seocndary to MS
Near reactions
Pupils constrict
Eyes converge
Lens becomes more convex by contraction of ciliary muscle
Adie’s tonic pupil
Parasympathetic denervation
Constricts poorly to light but reacts better to accomodation
Won’t constrict no matter which eye it was shown into
Argyll Robertson pupils
Prostitut’es
Bilateral small
Reduce in size on a near object but not when exposed to bright light
Neurosyphilis
If no red reflex
Then obstruction between cornea and retina…could be retinoblastoma
