The female reproductive cycle includes the events that occur over an average ___-day time period as a result of the _________ & ________ cycles

28

Ovarian & Uterine

1

The uterine cycle (menstrual cycle) involves changes that are occurring in the:

Uterus

2

Days 1-5

Known as "menses" (menstrual bleeding)

3

First day of bleeding is

Day 1 of menstrual cycle

4

________ is associated with blood flow that results from the rupture of the endometrial capillaries and sloughing of the tissue.

Menses

5

Days 6-13

"Proliferative" phase - period of rapid growth of endometrium in preparation for implantation of embryo

6

Days 14-28

"Secretory" phase - endometrial glands enlarge and increase secretion, arteries grow into endometrium

Begins at ovulation

7

If there is implantation of a fertilized ovum, what will develop?

Placenta

8

If there is no implantation by day 28, what begins?

The breakdown of the endometrium

9

Ovarian cycle consists of what 2 phases?

Follicular & Luteal

10

Follicular and luteal phase involves changes that occur in the _____ over the 28-day reproductive cycle

Ovaries

11

The follicular or preovulatory phase extends from ________ to _________.

Menstruation (day 1)

Ovulation (day 14)

12

Follicular phase includes the development of the ______ and _______ and corresponds to menses/proliferative phase of uterine cycle.

Ovum & follicle

13

Events that occur during follicular phase: (3)

Activation of primordial or primary follicles then to a mature (graafian) follicle

Follicular cells enlarge and create granulosa cells around primary oocyte

Eggs develop within follicles from primary oocytes to secondary oocytes, which are ovulated

14

Which oocytes are ovulated: primary or secondary?

Secondary

15

What are granulosa cells?

Cell layers around primary oocyte

Secrete fluid and estradiol

16

When do you get all of your egg cells?

At birth

17

Ovulation occurs on day:

14

18

After ovulation, the ovum is viable for:

12-24 hours

19

The luteal or postovulatory phase extends from days 15-28, just after __________ to the onset of _________

Ovulation

Menstration

20

The luteal phase corresponds to the _________ phase of the uterine cycle

Secretory

21

Luteal phase involves the transformation of the ruptured:

Follicle

22

Events during luteal phase (3):

After releasing ovum, follicle becomes corpus luteum (yellow body)

Corpus luteum grows and secretes estradiol and progesterone (tenfold increase)

If no prego, corpus luteum shrinks (day 22) and becomes scar tissue of corpus albicans (white body) by day 26

23
