Question 3

On the outer surface an ovary there is a single layer of cuboidal epithelium or low columnar epithelium. What is the name of this outer layer of the ovary?

A
Cortex
B
Stroma
C
Germinal epitherlium
D
Theca externa
E
Theca interna
F
Tunica albuginea
Question 4

A
Cortex
B
Stroma
C
Germinal epithelium
D
Theca externa
E
Theca interna
F
Tunica albuginea
Question 5

What cells migrate from the wall of the yolk sac into the indifferent gonad of the developing embryo during the 4th week of development?

A
Germinal cells
B
Primordial germ cells
C
Primary oocytes
D
Leydig cells
Question 6

A
Metaphase of meiosis I
B
Metaphase of meiosis II
C
Metaphase of mitosis I
D
Prophase of meiosis I
E
Prophase of meiosis II
Question 7

How long are the primary oocytes arrested in the phase from the previous question?

A
Until month 8 of fetal development
B
Until fertilization
C
Until ovulation
D
Until birth
Question 8

In what part of the ovary contains a large number of  primordial follicles?

A
Cortex
B
Hilum
C
Medulla
Question 9

What is the main hormone that helps primordial follicles develop into primary follicles?

A
Luteinizing hormone
B
Estrogen
C
Human chorionic gonadotropin
D
Follicle-stimulating hormone
E
Estriol
Question 10

In a primary follicle what is the name of the layer that forms between the layer of granulosa cells and the developing oocyte?

A
Cumulus oophorus
B
Theca externa
C
Theca interna
D
Zona pellucida
Question 11

What hormone does the theca interna secrete?

A
Luteinizing hormone
B
Estriol
C
17β Estradiol
Hint:
The theca enterna does not secrete 17β Estradiol; however, the theca interna is indirectly responsible for the production of 17β estradiol by supplying the neighboring granulosa cells with androstenedione that with the help of the enzyme aromatase can be used as a substrate for 17β estradiol.
D
Androstendione
