oogenesis Flashcards
oogenesis
female reproductive cells, produce diploid primary oocytes
where does oogenesis occur
in the ovaries
ovarian follicles
specialized structures in the cortex of the ovaries that surround growing and dividing oocytes
ovarian cycle
monthly process of maturation, ovulation and degeneration of tertiary ovarian follicle
phases of ovarian cycle
follicular (days 1-14, ovulation day is day 14): pre ovulation phase
literal phase: post ovulatory phase, day 14-28
uterine/menstrual cycle
repeating series of changes in the endometrium of the uterus
3 phases of the uterine cycle
menstrual, day 1-7
proliferative, end of menstruation to day 14
secretory phase: days 14-28
estrogen function
Development and maintenance of female reproductive structures, seConary sex characteristics, and the breasts.
3 types of estrogen
estradiol (most abundant)
estrone
estriol
progesterone function
works with estrogens to prepare the endometrium for implantation and the mammary glands for milk synthesis
relaxin function
produced monthly to relax the uterus by inhibiting contractions (making it easier for a fertilized ovum to implant in the uterus)
FSH role in female reproductive cycle
development of ovarian follicles and secretion of estrogens by the ovaries
LH role in female reproductive cycle
further development of ovarian follicles, ovulation, and the secretion of estrogens and progesterone by the ovaries
