|
4 phases of femal reporductive cycle are:
|
menstrual days 1-5
preovulatory days 6-13 ovulation days 14 postovulatory 15-28 |
|
|
ovary: 20 or so follicles bega to develop 6 days vefore are secreting estrogen
uterus: declining levels of progesterone cause arteries in lining layer ot constrict lining tissue dies |
mentrual phase
|
|
|
ovary: primary follice develops into secondary and is dominant, estrogen increase, esp LH increase, becomes Graafian follicle.
Uterus: increase in estrogen thickened and repaired stratum functionalis ( liner) |
preovulatory phase
|
|
|
rupture of graafian follicle , rls of secondary oocye into pelvic cavity.
DAY 14 |
ovulation
|
|
|
what causes ovulation
|
LH spike which causes it to rupture form ovary
|
|
|
ruptured follice left on the ovary
|
corpus hemorrhagicum
|
|
|
what hapens after ovualtion?
|
follicle collapses , other follicular cells absorb it, grow and form the corpus luteum or yellow body under the influence of LH
|
|
|
Ovary: both estrogen and prigesterone secreted in LG quantities by corpus luteum
Uterus: hormones from corpus luteum promote thickening of endometrium |
postovulatory phase
|
|

|
the corpus albicans
