Cell Flashcards
primary cilium is present in which cells
all cells
why don’t primary cilium move
they lack middle 2 of the 9+2
eg of a disease involving primary cilium
PKD
two types of giant cells
langerhans type (crescent) foreign body type (central)
koilocyte
big more colorful nuclei with irregular nuclear membrane and perinulear halo (think about nucleus and cytopathic effect)
koilocyte is typical of
HPV infection (p16)
hemosiderin is usally seen in
macrophages (eat RBC and Hb after Hge)
stony hard tumors are described as
scirrhous
adenoma
benign epithelial neoplasm
papillary cystadenoma
adenoma (gland)
cyst (cystic)
papillary (papillary projections)
hamartoma vs choristoma
choristoma pancreatic tissue in stomach
anaplastic
undifferentiated
dysplasia means
disordered growth
malignant neoplasm def
infiltrate, invade and metastasize
malignant cells def
pleomorphic, high NC ratio, hyperchromatic, nuceloli, loss of polarity, abnormal mitoses
grading means
differentiation status
hemidesmosome
basal surface to basal lamina
tight junction
don’t allow passage of anything
(zonula occludens?)
desmosome and hemidesmosome are of — filaments
intermediate
gap junction allow
passage of things
adherens junction is made up of
actin
gap, tight (occludens), hemidesmosome are
easy to remember
zonula adherens and desmosome are
not easy to remember
may be desmosome (intermediate filaments just like hemidesmosome)
PAS stain red for
carbohydrates
