Femal Reproductive Cycle
|
Two Cycles:
Ovarian Endometrial |
|
|
Ovarian Cycle
|
Three phases:
Follicular ovualtory Luteal |
|
|
Follicular Cycle
|
FSH (Follicle Stimulating leads to maturing of several follicles
|
|
|
Ovulatory Phase
|
LH(Lutenizing Hormone)Secretion rises follicle ruptures, releases ovum which is captured by fimbriae of fallopian tube, transport of ovum by muscular contractions (cannot move on its own)
|
|
|
Luteal Phase
|
Collaspsed follicle become Corpus Luteum (yellow body); secretes estrogen and progesterone to prepare endometrium until placenta tales over (6-8 wks)
*No fertiliztion corpus lutei, regresses |
|
|
Endometrial cycle
|
Proliferative phase:
Endometrium- under influence |
|
|
Proliferative phase
|
Endometrium- under influence of estrogen from maturing ovarian follicles
|
|
|
Secretory Phase
|
endometrium secretes glycogen, protei, lipids, and minerals to nourish the ovum
|
|
|
Menstrual phase
|
No fertilization, corpus luteum regtesses, estrogen and progestrone fall, endometrium ishcemic and necrotic, dies, necrotic areas seperate leading to menstrual flow
|
|
|
Prefertilization
|
Fatcs:
Sperm (24-72hrs) Ovum (24hrs) Transportaion: seminal fluid coagulates upon entry, sperm transported by uteine contraction and tail |
|
|
Fetetilization
|
Ampulla: outer 1/3 of tubes Zona reaction: membranes of ovum harden
cell membranes of sperm and ovum fuses, breakdown 23+23=46 Zygote by 4th day |
|
|
Cell Multiplication
|
Clevage: increases number of cells,not size
Morula: solid ball 12-16 cells Blastocyst: sac of cell inner nass (becomes aminon and fetus) outer mass (chorion and placenta) |
|
|
Implantation
|
Blastocyst drifts for 2-4 days before beginning implantation
*Endometrium in secretory phase |
