22
Q

What is the lining of the surface of teh ovary?

A

Simple cuboidal

23
Q

What is the outermost layer of the uretine tubes, and is composed of mesothelium and a thin layer of CT?

A

Serosa

24
Q

What is the the uterine tube wall layer that has a thick circular and a thin longutidunal segment?

A

Muscularis

25
Q

What is the lining of the mucosal layer of the uterine tubes?

A

Simple columnar

26
Q

What is the layer of the endometriym that is the functiuonal layer, is thick, and is sloughed off at menstration?

A

Stratum functionale

27
Q

What is the layer of endometrium which is hte basal layer, and is retained during menstation?

A

Stratum basale

28
Q

What is the lining of the endometrium?

A

Simple columnar

29
Q

What is contained in the muddle muscler layer of the myometrium?

A

many large blood bessels and lymphatics (stratum vasculare)

30
Q

Describe the arterial branches from uterine a to the endometrium.

A

Uterine a –> radial branch –> straight a + spiral a –> branch and dump into lacunae

31
Q

Which phase of the menstrual ccle is under the influence of estrogens?

A

proliferative phase

32
Q

What happens during the proliferative phase?

A

stratum basale grows
stromal cells grow and secrete ground usbtance
spiral aa lengthen

33
Q

What happens during the secretory phase, under the influence of progesterone?

A 
stratum functionale enlarges
glands enlarge and corkscrew
epithelial cells grow
spinal aa coil
stromal cells become decidual cells, which favors implanbtation
34
Q

There is sequamation during the menstral phase unil what point?

A

Until only the stratum basale remains

35
Q

True or False: cervical mucosa is sloughed off during menstration

A

False

36
Q

What happens to the cervical mucosal glands during mesntration?

A

They grow and secret a lot of mucus

37
Q

These are the cysts that form from a blockage of the mucosal glands, which leads to an enlarged cervix.

A

Nabothian cyts

38
Q

This is the zone where the cervix goes from a simple columnar epithelium to a stratified squamous.

A

Transformation zone

39
Q

Which side of the cervix has the simple comolumnar epithelium?

A

endocervix

40
Q

Which side of the cervix has the stratified squamous epithelium?

A

Ectocervix

41
Q

The metaplastic change of cervical cellsfrom columnar –> squamous can predispose to what condition?

A

Cancer

42
Q

A

Estrogen

51
