|
|
28 day Cycle with NO pregnancy. what happens on day 14
|
secondary oocyte locked in Metaphase II is released (ovulation), yellow scar is formed called corpus luteum, corpus luteum becomes an endocrine gland which will produce progesterone, "the" hormone of pregnancy
|
|
|
day 21 of cycle with NO pregnancy
|
pituitary is producing high levels of RH which is causing the corpus luteum to produce high levels of progesterone
|
|
|
day 28 of NO pregnancy
|
falling levels of LH and progesterone cause a reduction of blood flow to the endometrium. without adequte O2 and glucose the endometrium dies (necrotic endometrium)
|
|
|
day 1-5 of NO pregnancy
|
necrotic endometrium and blood are released from body as menstrual flows
|
|
|
High levels of progesterone feedback negatively on placenta shutting off what?
|
chorionic gonadotropin
|
|
|
during months 4-9, placenta produces
|
progesterone
|
|
|
during the 9th month, oxytocin released from posterior lobe of pituitary causes
|
labor contractions and milk letdown
|
|
|
Days 5-12 on menstrual cycle WITH pregnancy
|
anterior lobe of pituitary gland releases FSH which causes all 440,000 primary oocytes to begin a developmental "race." estrogens are produced.
Day 12 high levels of FSH cause primary follicles to produce high levels of estrogens feedback negatively on the pituitary which results in FSH being shut off, resulting in estrogens to shut off. |
|
|
Day 14 WITH pregnancy causes:
|
1. ovulation 2. Formation of Corpus Luteum 3. CL to produce progesterone
|
|
|
Day 21 WITH pregnancy
|
High levels of progesterone produced by corpus luteum feedback negatively on the pituitary to shut off LH
|
|
|
On Day 21 the zygote has done what?
|
it has been carried by cilia to the uterus where it has implanted into the endometrium and formed the mother/baby connection
|
|
|
any male with a sperm count of less than 20 million sperm per cc is called
|
infertia
|
|
|
as soon as placenta is formed it...
|
begins to produce chorionic gonadotropins which take the place of LH to continue to stimulate the corpus luteum to produce the hormone of pregnancy
|
|
|
anterior lobe of pituitary produces prolactin which stimulates...
|
mammary glands to produce milk
|
|
|
pregnancy tests test for
|
the presence of chorionic gonadotropin
|
