...

how will hormone levels change following ovuation

...

understand how the follicles change and mature during the ovarian cycle

...

what hormones will trigger the maturation of the ovarian follicles

...

what role does progesterone play during the luteal phase

...

what triggers meiosis II to begin? at what point will it pause?

...

what types of cells are produced in this process?are those cells haploid or diploid?

...

when does meiosis II occur in female?

...

which hormone triggers ovulaion

...

what will happen to those cells

1. oogonium-remians as a stem cell 2.primary oocyte-go through meiosis

functions of the layers of the endometrium

1.functional zone-contains most of uterine glands,undergoes dramatic change in thickness during menstrual cycle 2.basilar zone-attaches endometrium to the myometrium

list the processes involved in spermatogenesis list the pathway that sperm moves through

1.mitosis of spermatogonia 2.meiosis-produces spermatid 3.spemiogenesis-maturation of sperm starts at seminiferous tubules

what type of cells are produced as a result of mitosis during oogenesis?

1st polar body and primary oocyte

what cells are produced as a result of mitosis in males? are those cells haploid or diploid?

2n daughter cells they are diploid

when does meiosis I occur in females? at what point doe this process pause?

3-7 months of gestation pauses at prophase 1 until puberty

what cells are produced during meiosis II?are they haploid or diploid?

4 spermatids haploid

when does mitosis occur in females?

all mitotic division are completed prior to birth

fallegellum

allows sperm to swim

at the end of mitosis are the cells produced haploid or diploid?

diploid

how does the utherine lining change during proliferative phase? what hormone causes this?

estrogen causes epithelial cells in functional zone divide-thickens layer

two phases that comprise the ovarian cycle

follicular phase (preovulation), luteal phase(postovulation)

which layer of the utherine lining degenerates during menses phase

functional zone

know how levels of progesterone, estrogen, GnRH, LH, inhibit, and FSH change during proliferative phase

high levels of GnRH, LH and estrogen spike in FSH and inhibit low levels of progesterone

know the levels of estrogen, LH, FSH, inhibit, GnRH and progesterone will change during the secretory phase

low levels of GnRH, LH, FSH high level of progesterone, inhibit and estrogen if no fertilization happens-progesterone will then drop,high inhibit prevents follicle maturation

when does meiosis II finish?

mature ovum is fertilized

at which phase does the utherine cycle begin?

menes

levels of estrogen, LH, FSH,inhibit and FSH change during menes phase

menes phase-homrones are low (GnRH, LH, FSH, estrogen, progesterone)

list the phases of the utherine cycle

menes, proliferative, secretory

acorosome

on head of sperm -allows sperm to penetrate ovum

stem cells that are part of oogenesis are referred to as?

oogonium

lis the layers of the uterine wall

perimetrium myometrium endometrium

define spemiogenesis

physical maturation of sperm each spermatid matures into a spermatozoon(sperm)

At the end of meiosis I what cells are produced? are the cells haploid or diploid?

produce 2 secondary spermatocytes-haploid

when will meiosis I begin again?

puberty

what are the stem cells that are involved in spermatogenesis referred to as?

spermatogonium

what happens to those cells?

spermatogonium(2n divide again) primary spermatocyte 2n-meiosis

how does the uterine lining change during the secretory phase?

thickens more for preparing implantations
