9. Uterine Cycle

10. maintains thickness. of uterine lining (endometrium)
Female Hormones
-pituitary
From the Brain
FSH ___________________________
__________________
LH ________________________
ovulation - tells ovaries to release egg, produce progesterone and stimulates follicle to become
corpus luteum
From the ovaries:
_____________
thickening of the uterine lining female secondary
sex characteristics (auxiliary and pubic hair, wide hips,
breasts development)
_______________
maintains thickness. of uterine lining (endometrium)
growth of corpus luteum

11. follicle in the ovary grows
Uterine Cycle
Duration: days
1-5 Menstruation:
6-14 Follicular phase
14-15 Ovulation
Luteal phase
lining of the uterus and blood are discharged
follicle in the ovary grows
egg released from ovary

12. Follicular Phase Uterine Cycle / Menstrual Cycle 28 days
immature egg stimulated by ________ to complete its first meiotic division
follicle which surround the maturing egg releases _____________ which causes mitotic divisions of cells in the uterine lining causing the lining to thicken
elevated estrogen in turn tells the pituitary gland to release LH,
duration: 7 days: Day 7- 14

13. Ovulation
- an elevation in LH causes the follicle to rupture and _________________
- duration: ___________ (day 14 of the cycle)

14. Luteal Phase: The ruptured follicle grows larger and becomes a
structure called the ______________(yellow body)
The corpus luteum begins to secrete _____________ and ________________ which stimulates continued thickening of the uterine lining
If no fertilization - corpus luteum stops secreting estrogen and progesterone and _____________________starts
Duration 14 days

15. process: Fertilization union of sperm and egg
If ovulation occurs anytime from ________________________after _____________________ fertilization may result in the fallopian tubes
process:
1.The enzymes in the acrosome of several sperm break
down the egg's _____________________
2. the head of __________________ cell fuses with the egg's cell
membrane
3.Only the _____________ and _______________ enter the cytoplasm
of the egg
4. egg cell membrane changes to prevent other sperm
from entering

16. 8 weeks Events of Pregnancy - most dramatic changes
Implantation: the zygote (fertilized egg) forms a ball of
cells and travels down the fallopian tubes to the uterus
and burrows into the uterine wall.
Events of Pregnancy
First Trimester - ________________________
- most dramatic changes

called an ___________________
- three primary germ layers form: __________________
______________ _______________ all body tissues will form
from these layers.
- placenta grows
-brain, spinal cord develop
-heart begins ___________________
- by 5 weeks - human features such as _______ & ________ form
- week 8 on till birth referred to as ________________
8 weeks

17. Second Trimester - _____________

-kicks feet
-eyes open
-_________________ in length

18. Third Trimester - _____________________
-Fetus grows quickly
-can see light and darkness
-can react to ______________
-deveops fat deposits under skin

19. Embryonic Membranes
amniotic sac - contains fluid which cushions embryo from
shock, mechanical injury and keeps it moist
chorion - forms small fingerlike projections called chrionic villi which will develop into the placenta and umbilical cord which carry food and oxygen to fetus and wastes away

20. 270 days after fertilization
Birth
270 days after fertilization
1. ______________ from fetal membranes initiate
childbirth
2. amniotic sac ________________
3. contractions of the uterus get stronger
contractions eventually push the baby
out through the __________ and though the ______
4. __________________and ____________ are expelled
about 30 minutes after birth ("after birth")
