Some notes on the last Embrio lecture ....

1-no pregnancy occurs--->carpus luteum will shrink until degenerateàprogesterone levels will go down--->C.luteum will be converted into C.albicans(nearly at day 27)àendometrium replaced by myometrium---> second period will start.

2-follicle:ovum surrounded by nourishing cells

3-estrogen--->first 14 days of period-->before ovulation
Progesterone--->second 14 days of period--->after ovulation

4-carpus luteum is formed by remains of 2ry oocyte after ovulation

5-carpus luteum is responsible for:
-second phase of female period
-pregnancy
-progesterone secretions

6-ovary forms before 5th week

7-ovulation(of 2ry oocyte) occurs at day 14

8-ovarian layers after modified peritoneum are:
-Germinal epithelium
-Tunica albuginea
-ovarian cortical region(cortex of ovary)
-medulla

9-hilum:receives arterial blood supply and sends Venus drainage to and from ovary--->by ovarian blood vessels

10-follicles--->primitive(primordial)
---->growing (secondary)
