Robbins Ch 22 - Lecture 2 Flashcards
shedding of the functionalis
menses
straight tubular glands line with regular, tall pseudostratified columnar cells w/ no evidence of mucus secretion or vacuolation
proliferative phase
appearance of secretory vacuoles beneath the nuclei in the gladular epi
postovulation
spiral arterioles, increase in ground substance and edema btwn stromal cells
late secretory phase
predecidual change occurs in the
late secretory phase
drives the prolideration of both glands and strom
estrogen
down-regulates expression of estrogen receptor in glands and stroma
progesterone
causes differentiation of the glands and function changes in stromal cells
progesterone
most frequent cause of dysfunctional uterine bleeding
anovulation
stromal condensation, eosinophilic epithelial metaplasia w/out glandular secretory changes and stromal pre-decicualization
anovulation
infertility ass’d with increased bleeding or amenorrhea d/t inadequate progesterone production during post-ovulatory period
inadequate luteal phase
acute endometritis is caused by
GAS, staphlyococci or another bacteria post delivery or miscarriage
ectopic endometrial tisse at a site outside of the uterus
endometriosis
5 MC sites of endometriosis
ovaries> uterine ligaments > rectovaginal septum > cul de sac > pelvic peritoneum
MC age group of endometriosis
active reproductive age - 3rd/4th decade
endometric implants in endometreosis show
release of proinflammatory factors, increased estrogen production by stromal cells
genetic changes in endmetriosis indicating possible clear cell ovarian cancer
PTEN, ARID1A
chocolate cysts
endometriosis that has cause fibrosis of the ovaries
presence of endometiral tissues within the uertine wall
adenomyosis
endometrial polyps have been ass’d with
tamoxifen
