VERIFIED ANSWERS) LATEST UPDATED VERSION
|GUARANTEED PASS. (REVISED EXAM)
MHC - ANSWER: Major Histocompatibilty Complex, processes and presents antigens
subconjunctival hemorrhage - ANSWER: Blood in the eye, resolves like a bruise
pterygium - ANSWER: Surfer's Eye, triangle of conjunctiva. Drops if inflamed, surgery
if blocking vision, sunglasses in all cases.
Pinguecula - ANSWER: a harmless yellowish triangular nodule in the bulbar
conjunctiva on either side of the iris that stops at the limbus, from too much sun
chalazion - ANSWER: Inflamed meibomian (eye sweat) gland, I&D if large
hordeolum - ANSWER: Stye
Herpes Keratitis - ANSWER: Fern-like damage pattern, like corneal abrasion.
Permanent damage.
Rinne test - ANSWER: bone conduction vs air conduction
Weber test - ANSWER: tuning fork unicorn
cheilosis - ANSWER: Cracks in the corners of the mouth, from drool (dentures, paci)
Hairy Leukoplakia - ANSWER: EBV glossitis; pre-AIDS defining lesion; not precursor to
cancer
Koplik spots - ANSWER: Measles in the mouth
torus palatinus - ANSWER: benign bony ridge running in the middle of the hard
palate
Avulsed tooth - ANSWER: Put in cool milk
Triploidy - ANSWER: 3 of all chromosomes; normal in some cells, miscarriage if
present in all cells
Trisomy 21 - ANSWER: Down syndrome
, Trisomy X - ANSWER: Mostly normal, may have repro difficulties and mild mental
impairment
Turner Syndrome - ANSWER: No Y chromosome, only one X, short, no ovaries, aortic
coarctation, neck webbing. Treat with E.
Klinefelter syndrome - ANSWER: XXY, androgynous traits
Cri du chat syndrome - ANSWER: A deletion of the short arm of chromosome 5
associated with an array of congenital malformations, the most characteristic of
which is an infant cry that resembles a meowing cat; microcephaly, heart defects
chromosomal inversion - ANSWER: When part of the chromosome becomes oriented
in the reverse of its usual direction; usually normal in the parent but causes severe
defect in children
Robertsonian translocation - ANSWER: Translocation in which the long arms of two
acrocentric chromosomes become joined to a common centromere, resulting in a
chromosome with two long arms and a deletion. Causes deletions/functional
trisomies in offspring
Fragile X Syndrome - ANSWER: >200 CGG sequences in the first X exon; causes
intellectual disability
Achondroplasia - ANSWER: A form of human dwarfism caused by a single dominant
allele; the homozygous condition is lethal
Retinoblastoma - ANSWER: Autosomal dominant, ~90% penetrance, congenital eye
cancer
Huntington's disease - ANSWER: Autosomal dominant adult onset dementia and
chorea
von Recklinghausen disease - ANSWER: Neurofibromatosis 1, autosomal dominant,
varied expressivity: cafe au lait spots up through tumors
cystic fibrosis - ANSWER: Autosomal recessive; chloride channel defect leads to
sticky mucus. 1/25 white people is a carrier.
Barr bodies - ANSWER: mostly inactivated X chromosomes, usually all but one (so
none in XY, one in XX, two in XXX); coin flip cell by cell. 15% genes still active
Map unit - ANSWER: 1% recombination rate; a distance of approx. 1 million base
pairs
