1

What happens to the ovary at menopause

Reduced function - reduced response to pituitary hormones, reduced hormone production

2

Which ligaments stabilise the ovary

Ovarian and suspensory ligaments

3

T/F The follicles are found in the medulla of the ovary

False, they are found in the cortex. Medulla is largely connective tissue and blood vessels

4

What cells are found in the cortical stroma?

highly cellular connective tissue
scattered smooth muscle cells
oocytes

5

Why is there scar tissue at the ovary cortex

scar tissue is made due to ovulation (tear due to oocyte)

6

What layers are found superficial to the ovarian cortex

single layer of epithelium on the outside, followed by tunica albuginea

7

What cells surround the primordial oocyte

squamous follicle cells surrounded by common basal lamina (type IV collagen)

8

T/F Meiosis has already begun in a primordial oocyte

True, it is arrested in the prophase of meiosis 1

9

T/F zona pellucida sits superficial to the follicle cells

False, they sit between the oocyte and the follicle cells

10

Which cell matures into granulosa cell?

follicular cells

11

What's stratum granulosum

multilayered, cuboidal granulosa cells

12

T/F Theca cells sit superficial to the granulosa cells

True

13

Which cells mature into theca cells?

the outer stromal cells

14

What is the antrum of the secondary oocyte?

it's a fluid filled cavity that surrounds the oocyte

15

What is the cumulus oophorus

a stalk of granulosa cells that suspend the oocyte in the antrum

16

What is the corona radiata?

granulosa cell layer surround the oocyte after ovulation

17

What is the name given to a mature follicle?

Graafian follicle

18

How is corpus luteum formed?

after ovulation, stromal, granulosa and thecal cells invade the inner cavity and differentiate into luteal cells, forming the CL

19

What is involution

atrophy with time

20

What are the three layers of fallopian tube?

outer serosa, middle smooth muscle muscularis and inner mucosa

21

Why is the fallopian tube epithelium ciliated?

It can beat the peritoneal fluid and move the oocyte

22

How is isthmus structurally different to ampulla

it has more smooth muscle and less mucosal lining

23

How does the oocyte get nutrients when moving down the fallopian tube?

epithelium secrets fluid that provides nutrients

24

What are the three layers of uterine wall?

outer perimetrium
middle myometrium
inner endometrium

25

How many layers of smooth muscle can be found in the myometrium

three: inner and outer longitudinal muscle, with a middle circular layer

26

T/F The thickened wall regress after pregnancy

False, the thickened wall is retained after first pregnancy

27

T/F The entire endometrial is covered by ciliated simple epithelium

False, there are spots of non-ciliated, secretory columnar cells connective to glands

28

How far does the secretory gland extend in the endometrium

penetrates into lamina propria

29

What artery supplies the endometrial mucosa

helical arteries from the myometrium

30

How does the endometrium change microscopically from proliferative to secretory phase

glands enlarge, and secretion accumulates

epithelial, stromal and vascular cells proliferate
