Neurologic Examination Flashcards
Any detectable change produced by neural activation of an effector
Behavior
If restricted to one part of the examination, this is the most efficient method of physical diagnosis
Inspection
site of deposition of the Kayser-Fleischer ring
Descemet membrane
Kayser-Fleischer ring can be found in what other conditions aside from Wilson hepatolenticular degeneration?
Aceruloplasmimemia, Primary biliary cirrhosis, Hardikar syndrome, hypercupremia
A unilateral corneal arcus is diagnostic of what condition?
Carotid Artery Stenosis
Intercanthal distance of normal eyes in the newborn
1.9 cm
Condition when the medial orbital walls and consequently the eyes are set too far apart?
Orbital Hypertelorism
Facial hemangiomas in Sturge-Weber Syndrome occurs in what distribution of the trigeminal nerve?
V1 distribution
Pathologic bruits become audible over the carotids after how many % stenosis?
50%
Peripheral ocular motor nerves consists of
III, IV, VI and carotid sympathetic nerve
T/F: The mind projects afferent impulses to their usual site of origin in all sensory systems
True
The retinopretectal tract is for
pupilloconstriction to light
The retinohypothalamic tract is for
diurnal cycle of sleep and wakefulness
The retinogeniculate tract is for
vision
Cones mediate
central field of vision, visual acuity, color vision
Rods mediate
peripheral field of vision, night vision and motion detection
Extent of the total field of peripheral vision
180 degrees wide
A central scotoma that blends with the blind spot is called
centrocecal scotoma (paracentral-near the point of central vision but detached from it)
Eye to eye distance during the confrontation testing
50cm
Characteristics of cortical blindness
1) complete blindness with no light perception and no response to a menacing gesture
2) loss of smooth pursuit
3) No optokinetic nystagmus
4) Normal pupillary reactions, fundoscopic examination and no nystagmus
5) Denial of blindness
T/F: Visible pulsations occur in nearly 90% of normal patients when both eyes are examined.
True
Swollen disc, normal vision
papilledema
Swollen disc, blurred vision
papillitis
Normal disc, blurred vision
Acute retrobulbar neuritis
