ovary
|
|
|
what kind of oocytes to primordial and primary follicles contain?
|
primary oocytes arrested in meiosis I prophase
|
|
|
what is primordial follicle?
|
oocyte + layer of flat granulosa cells
|
|
|
what is a primary follicle?
|
oocyte + cuboidal granulosa cells
|
|
|
what is a secondary follicle also known as?
|
antrum
|
|
|
what are mature, secondary follicles with antrum, granulosa cells, and teca interna and externa called?
|
vesicular, tertiary, mature, or graffian follicle
|
|
|
what happens to traffian follicles right before ovulation?
|
1st meiotic division is completed and we have a secondary oocyte
|
|
|
what to theca cells do during the follicular phase of the ovarian cycle?
|
supplies androstenedione to granulosa cells, which use aromatase to make estrogen
|
|
|
what happens to the secondary oocyte at ovulation?
|
will enter meiotic division II but arrest in metaphase
|
|
|
what causes ovulation?
|
spike in LH causes rupture of mature follicle, liberation of oocyte
|
|
|
what happens in the luteal phase?
|
follicle turns into corpus luteum
progesterone facilitates maturation of tissue glands in endometrium |
|
|
what hormones are inversely proportional in luteal phase?
|
progesterone and estrogen
|
|
|
what does the corpus luteum become in the luteal phase?
|
corpus albicans
|
|
|
what hormone is released from hypothalamus for ovarian function?
|
GnRH
|
|
|
what is the function of GnRH?
|
release of FSh and LH from anterior pituitary
|
|
|
what is the function of FSH?
|
causes growth of follicles adn LH receptors on granulosa cells
|
|
|
what hormone to granulosa ells secrete?
|
estrogen, inhibin, and activin
|
|
|
what do estrogen, inhibin and activin do?
|
regulate FSh
|
|
|
what happens at day 14 in ovarian cycle?
|
estrogen levels initiate LH surge
|
|
|
what does the LH surge cause?
|
Meiosis I completed to form secondary oocyte
secondary oocyte enters meiosis II (arrests in metaphse) formatin of corpus luteum by theca adn granulosa cels |
|
|
when does fertilization occur?
|
day 14-21
|
|
|
what move the oocyte closer to the uterus?
|
cilia
|
|

|
estrogen
|
|
|
what hormone drives the secretory phase of the menstrual cycle?
|
progesterone
|
|
|
what causes the low pH in the vagina?
|
epithelial cells during puberty have lots of glycogen that is broken down by lactobacilli
|
|
|
what kind of muscle does the interla sphincter of the bladder have?
|
smooth muscle
|
|
|
