BIOD 152 MODULE 6
1. What is the hood over the clitoris called?
Answer: prepuce
2. In the vulva, what is the vestibule?
Answer: It surrounds urethral & vaginal orifices
3. How many lobules does each mammary gland contain?
Answer: 12-24 lobules
4. Where does the mammary duct begin and what does it divide into?
Answer:
-nipple
-divides into other ducts ending in sacs called alveoli
5. What are alveoli in the mammary glands?
Answer: cells that produce milk
-in a non-lactating breast, ducts out number the alveoli
6. How and when does lactation begin?
Answer: After delivery, estrogen and progesterone no longer suppress prolactin which is
needed for milk production
7. What is colostrum?
Answer:
-yellow-white fluid
-production prior to milk production
-higher concentration of protein than breast milk
8. what is the hormone needed for milk production?
Answer: prolactin
9. What is oogenesis, when odes it occur and when is it complete?
Answer:
-production of eggs in the ovaries
-occurs during development of the fetus in the womb
-is complete by the time of birth
10. True or false: a female is born with all of her eggs and doesn't producemore after birth
Answer: true
, 11. When does menarche begin and what is it?
Answer:
-at first menstruation
-is the beginning of reproductive lifetime
12. When does the reproductive lifetime end?
Answer: at menopause
13. What are primary ooctyes?
Answer: 2 daughter cells that are the result of mitoticdivision of an oogonia (female stem cell)
14. What are the primary ooctyes covered by?
Answer: primary follicles
15. When a female reaches puberty, what does The anterior pituitary glandstart secreting?
Answer: Follicle-stimulating hormone (FSH)
16. What does Follicle-stimulating hormone (FSH) do?
Answer: causes a few follicles tomature each month causing the primary oocyte in the follicle
to undergo its first meiotic division into 2 daughter cells (the secondary oocyte and the first
polar body)
17. When does the first meiotic division occur?
Answer: When a new follicle matures andis released for ovulation
18. Why is a polar body produced when the primary oocyte in the follicle undergoes its first
meiotic division?
Answer:
-so that the chromosomes divide properly
-but all the cytoplasm is "donated" from the polar body to the secondary oocyte incase of
fertilization
19. What happens if the secondary oocyte is united with a sperm?
Answer: second meiotic division occurs producing a 2nd polar body and an ovum with 23
chromosomes
20. When does the 2nd meiotic division occur?
Answer: if the secondary oocyte isfertilized with a sperm
21. Mitosis vs. Meiosis
Answer:
-Mitosis: cells divide into 2 identical cells, each with 46chromosomes
-Meiosis: cells divide into 4 cells, each with 23 chromosomes, each daughter cell isunique
