- Mullarian duct (paramesonephric duct)
- The paramesonephric ducts merge together
Male: appendix testis
Q2:
Homologues:
Other 2/3rd of the vagina, vulva, urethra?

Scrotum
urethral swellings
Q2:
The female labia minora is equivalent to what male structure?
Spongy urethra
Urethral fold
Q2:

Prostate
(urogenital sinus)
- Batholin’s glands = Cowper’s glands
- Bladder = Bladder
- Urethra, L vagina = urethra
Q2:

Rete testis
Wolffian Duct: (male: SEVen up) –> Seminal vesicles, epididymus, vas defeens
Q3:
What is the gene on the Y chromosome that determines sex.
Is it located on the short or long arm of the Y chromosome.
- SRY gene
- Shorter arm.
Q2:
In the development of external genitalia of female – The genital tubercle becomes the?
Clitoris
– does not lengthen, in male –> phallus (penis)
Q2: The genital folds become?
The spongy urethra = male
Labia minora = female
(remain unfused)
Q2: The genital swellings become?
Scrotum = male
labia majora = female
Q4:
Know in general for the migration of the germ cell. Where do they start, creep up and end?
Start: Mesenchymal or stem cells (future sperm or eggs) that develop in the wall of the yolk sac.
-yolk sac and migrate along the hindgut
End: in the gonadal (genital) ridge (soon to be ovary)
- (germ cells have to be inserted into the sex cords)–Primordial germ cells migrate until they reach the gonadal ridges and penetrate into the primitive gonad by the sixth week
Q5:
Some of the primordial germ cells are surrounded by what kind of cells?
cells of the primitive sex cord
Q5:
Sex cord cells become what kind of cells (once we have the formation of the ovaries)?
-At what month?
follicular cells at month 4.
