Flashcards in Lecture 4 - Female Reproductive Tract II Deck (13):
Uterial gorwth after implantation?
osetrogen (and progesterone) stretch existing cells following ectotopic implantation
preparation for pregnancy (not necessary), stroma becomes oedematous, fibroblasts expand and fill with glycogen; sometimes occurs spontaneously during periods
branches of uterine arteries become arcuate arteries that encircle endometrium with radial artery branches?
Radial artery branches?
supply straight arteries (supply basal zone), and spiral arteries (functional zone/placenta)
Timing ovulation consideration?
follicular/proliferative phase is longer and more variable in length than the luteal/secretory phase
Period anthropology from ancestors?
earlier puberty, earlier motherhood, more children, significantly less cycles over lifetime
Histological signs of proliferative phase?
straight stroma, mitotic figures
Histological signs of luteal phase?
bent glands, glandular secretions, basal oedema
Oestrogen in uterus?
epithelial and stromal cell proliferation, oedema, gland secretion, progesterone receptor synthesis, myometric activity
Progesterone in uterus?
gland secretions of luteal, stromal cell differentiation, inhibit myometric activity
Endometriosis starting theories?
transport of cells through blood, lymphatics and stem cells
infects junctional site between layers - location of pap smear
