1

when does the reproductive system develop?

5-6th week

2

what week is sex identification possible?

8th week

3

development of the gonads?

-coelomic epithelium
-inner mesenchyme tissue
-primordial germ cell

4

what is the genital ridge covered by?

coelum epithelium

5

the development of cells causes the genital ridge to bulge into the?

coelum

6

what makes up the inner mass of the genital ridge?

mesenchyme

7

the cells within the genital ridge arrange themselves into what?

sex cords

8

the sex cords grow into underlying?

mesenchyme

9

when the sex cords grow into the mesenchyme they become?

primary sex cords

10

the indifferent gonad has what two thingsz?

cortex and medulla

11

the cortex has an outer layer and during development in males it? in females?

in males it regresses
in females the cortex develops

12

the medulla is the inner layer and during development in males it? in females?

in males it develops
in females it regresses

13

during the development of the ovaries the primordial germ cells migrate to the?

surface epithelium and forms the cortical cords

14

during the development of the ovaries at the 16th week, what happens?

the cortical cords break up into primordial follicles

15

the mesonephric ducts play an important role in which sex?

male reproductive system

16

what is formed from the mesonephric ducts in males?

epididymis
ductus deferens
ejaculatory duct
cranial part-efferent ?

17

in females the paramesonephric ducts develops where?

they develop on each side of the body

18

in females what ducts open into the coelum, pass caudally along the side of the mesonephric duct, and the caudal end fueses to form the Y shape?

paramesonephric ducts
uterovaginal- uterus and vagina

19

the genital tubercle develops where?

at the upper end of the cloacal

20

during the development of the genitalia labioscrotal _________ and urinogenital ______ develop

labioscrotal swelling and urinogenital folds develop

21

during development of the genitalia, the genital tubules elongates to form?

a phallus

22

what are some symptoms of ovarian hypoplasia?

-small ovary size
-poor breast development
-small uterus
-only some ovarian function

23

ovarian hypoplasia can be associated with what syndrome?

turner's syndrome

24

true or false
turner's syndrome can be unilateral or bilateral?

true
unilateral affected can give birth to a normal infant

25

Bilateral ovarian hypoplasia will contain what?

very few primordial germ cells

26

when affected by bilateral ovarian hypoplasia, six months after birth they will have no?

NO oocytes even after 6 months

27

during bilateral ovarian hypoplasia what stimulates the fetus' cells?

mother's hormones

28

during a bilateral ovarian hypoplasia few primordial germ cells reach what?

when migrating from yolk sac, few reach the genital ridges

29

during pure gonadal dysgenesis what do the germ cells do?

the germ cells do not migrate from the yolk sac

30

what is the karotype for those affected by pure gonadal dysgenesis?

normal karotype
