extra “X” chromosone (XXY)

Question 3

Edwards (trisomy 18)

Answer 3

extra 18th chromosome

Question 4

Question 6

Down syndrome (trisomy 21)

Answer 6

3 #21 chromosomes

Question 7

Primary follicle

Answer 7

estrogen producing

**primary= first stage of egg maturation

Question 8

Growing follicle

Answer 8

estrogen producing

second stage

Question 9

Graafian follicle

Answer 9

estrogen producing

3rd stage

Question 10

Ruptured follicle

Answer 10

estrogen producing

ovulation, very last stage

Question 11

Corpus luteum

Answer 11

progesterone producing

after ovulation, ruptured follicle turns into this, which eventually disintegrates

Question 12

FSH

Answer 12

-anterior pituitary

follicle stimulating hormone by growing and maturing the follicles

Question 13

LH

Answer 13

-anterior pituitary

luteinizing hormone, triggers ovulation

Question 14

Estrogen

Answer 14

-ovarian hormone
hormone that causes the appearance of the secondary sex characteristics in young women
*follicles

Question 15

Progesterone

Answer 15

-ovarian hormone
lasts 10-14 days
produced by the corpus luteum
major effects are exerted during pregnancy, prepares for milk production
*source of progesterone during pregnancy is placenta

Question 16

Zygote

Answer 16

fertilized egg

Question 17

Embryo

Answer 17

organism in its early stages of development, first 2 months after conception

Question 18

Zygote

Answer 18

fertilized egg

Question 19

Embryo

Answer 19

early stages of development(after zygote)

first 2 months after conception

Question 20

Ovarian follicle

Answer 20

tiny saclike structures that contain an immature egg

Question 21

Oocyte

Answer 21

immature egg, surrounded by one or more layers of follicle cells

Question 22

Antrum

Answer 22

fluid-filled central region

Question 23

Follicle

Answer 23

*vesicular or Graafian

mature after develoption of the antrum

Question 24

Ovulation

Answer 24

ejection of mature, developing egg from the ovary

*14th day of the 28 day cycle

Question 25

Oogenesis

Answer 25

when female gametes are produced, *beginning of an egg

Question 26

Ovaries

Answer 26

primary female reproductive organs
exocrine products: eggs/ova
endocrine products: estrogen and progesterone

Question 27

Mensis

Answer 27

(days 1-5)

• endometrium sloughs off
• bleeding 3-5 days

Question 28

Proliferate

Answer 28

(days 6-14)

• estrogen levels inc. bc of follicle growth
• endometrium heals
• glands form in endometrium
• endometrium blood supply inc.
• LH IS THE OVULATION TRIGGER

Question 29

Secretory

Answer 29

(days 15-28)

• CL inc. in size = pro. inc
• blood supply inc. to endometrium
• nutrients secreted into uterine cavity to sustain developing embryo until it implants

Question 30

Fertilization

Answer 30

• embryo produce hormone similar to LH making the CL keep producing progesterone
• pregnancy starts

Question 31

No fertilization

Answer 31

• CL eventually degenerates by days 25-28 = LH dec.
• ovarian hormones (PRO + EST) dec. at end of cycle-blood vessel kink
• dec. blood/O2/nutrients = tissue death
