LAB 1 Flashcards
Which hormone is a primary hormone from the brain which stimulates maximum estrogen levels
LH
What day do we see spiked estrogen levels and what does this represent
14 and ovulation
What is oogeneisis
Process where the female sex cells become mature ova
How many primary oocytes does a baby girl have
Half million
What develop arounf primary oocytes to form primary follicle
Granulosa cells
At puberty how many primary oocytes are there
400 000
Hypothalamus releases what
Gonadotropin releasing hormone
FSH promotes development of
Follicles and stimulates estrofen secretion
LH triggers _____ and promotes development of ________
Ovulation
Corpus luteum
Follicular phase is day _____ to ______
5 to 14
During follicular phas _____ causes primary oocytes to start growing
FSH
Primary follicle is surrounded by
Granulosa cells
In secondary follicle, granulosa cells start producing
Estrogen
Graafian follicle is
The one secondary follicle that becomes the dominant
When the graafian follicle is produced there is a spike in
Estrogen initiating the surge of LH to start ovulation
Mature graafian follicle antrum:
Follicular fluid
Mature graafian follicle theca folliculi 2 layer s
Theca externa
Thec interna
Mature graafian follicle theca externa
Touch outer layer of secondary cells
Mature graafian follicle theca interna
Supplies testosterone to the granulosa cells
Mature graafian follicle granulosa cells uses _______ to produce estrogen
Testosterone
Mature graafian follicle cumulus oophorus is the mound where ______ is supported
Ovum
Day 5-28 of the ovarian cycle is called
Luteal and progesterone phase
What maintains the Corpus luteum during the luteal and progesterone phase
LH
During the luteal and progesterone phase the corpus luteum produces a lot of
Progesterone
Progesterone is responsible for
Thickening endometrium
If fertilization does no occur, what happens in the endometrium
Water leaves blood vessels anf they contract causing ischemia
Lack of blood flow causes necrosis
Endometrium will slough off
Corpus luteum will regress into
Corpus albacans
If fertilization occurs where will hCG be produced
At site of implantation
HCG maintains
Corpus luteum —> maintaining the progesterone and thus endometrium
Progesterone desensitizes muscles in pregnancy so
No premature labour
