Palatoglossus
What is the only muscle with the root word PALAT that is not innervated by the vagus nerve?
tensor veli palatini

stria vascularis
Utricle (horizontal) and Saccule (vertical) contain what that detects linear acceleration?
Maculae
Semicircular canals contain what that detects angular acceleration?
Ampullae
The ciliary muscle is relaxed in (distant vision or near vision)?
distant (it relaxes and the lens flattens)
What is the fundoscopic finding in glaucoma?
optic disc atrophy with cupping
Which is more painful? (closed angle or open angle) glaucoma?
Closed angle is more painful
To test a person's inferior oblique, what should I have him do?
Look UP
To test a person's superior oblique what should I have him do?
Look down from an adducted position
What muscle does the long ciliary nerve innervate (pupillary sphincter or the radial)?
radial (long ciliary nerve is sympathetic); mydriasis
Describe pupillary light reflex?
light shone > CN2 > pretectal nucleus > both edinger westfall nuclei > Both CN 3
What is lost first in compression of the occulomotor nerve?
parasympathetics (outside of the eye) no accomodation; "blown Pupil"
What is the differnece in fibers that can cause upper quadrantic and lower quadrantic anopia?
Upper travel in the temporal; Lower travel in the parietal
A patient looks toward the left, but his right eye does not move and his left eye beats?
Right MLF lesion (internuclear opthalmoplegia)
What genes are associated with early onset Alzheimers?
APP, presenelin1, presenelin 2
What are complications of the B-amyloid senile plaques in Alzheimer?
Amyloid angiopathy > intracranial hemorrhage
What are Neurofibrillary Tangles?
abnormally phosphorylated tau proteins
Fronto-temporal atrophy, dementia, aphasia, change in personality?
Picks disease (pick bodies are tau protein)
A patient has dementia with parkinsonism and hallucinations?
Lewy body dementia
What do you use B-interferon therapy for?
MS
What disease is associated with albuminocytologic dissociation (increased CSF protein with normal cell count)
Guillain-Barre
Arysulfatase A deficiency with buildup of sulfatides; Impaired myelin sheath?
Metachromatic leukodystrophy
What seizure is associated with 3Hz waveforms?
absence (ethosuximide)
Treatment for migraines?
propranolo; sumatriptan
Inheritence of tuberous sclerosis?
autosomal dominant
Gene for NF1?
17.0
What is the cause of Menieres disease?
increased volume of endolymph
What brain tumor is associated with a chiken-wire capillary pattern and perinuclear halos?
oligodendroglioma
How can acetazolamide be used for glaucoma?
decreased aqeous humor secretion by decreased bicarbonate
How does latanoprost help with glaucoma?
increases outflow (prostaglandin); darkens the iris
2 opioid drugs used for diarrhea?
loperamide and diphenoxylate
Butorphanol?
partial agonist at opioid mu receptors (less respiratory depression)
1st line antiseizure medication for pregnant women and children?
phenobarbital
MAO for gabapentin?
GABA analog
MAO for topiramate?
Blocks Na; Increase GABA
MAO for Tiagabine?
inhibits GABA re-uptake

Which anti-seizure medication is associated with SLE-like syndrome?
Phenytoin
Which anti-seizure med is associated with neural tube defects in baby?
Valproic acid
What drug is usefull in night terrors and sleep-walking?
benzodiazepines ; shorten stage 4 sleep (delta)
What does blood solubility and lipid solubility help determine for anesthetic drugs?
Increased lipid solubility = Increased potency (decreased MAC); Decreased blood solubility = rapid induction
Slower induction by an anesthetic is due to a (high or low) blood/gas partition coeffcient?
High (increased blood solubility)
Induction by inhalational anesthetic will lead to (increased or decreased ) cerebral blood flow?
increased
Thiopental has a (increased or decreased) cerebral blood flow? Making it better for brain surgery?
decreased
Two types of local anesthetics ?
ester (procaine); amide (lidocaine)
Why are local anesthetics less effective in acidic (infected) tissue?
low pH causes anesthetic to be in charged form; cannot penetrate
What is the order of sensation loss with local anesthetics?
pain > temperature > touch > pressure
Which two dopamine agonists are ergot derived?
bromocriptine and pergolide; pramipexole and ropinrole are not
How can amantadine help in Parkinsons?
increase dopamine release
