Two types of cells of ovary

A

Granulosa Lutein
Theca lutein

25
Q

derived from: granulosa cells

A

Granulosa Lutein

26
Q

derived from Theca Interna cells

A

Theca lutein

27
Q

CL degenerates and forms
White scar called

A

Corpus Albicans

28
Q

Post-Ovulation:

A

10-12 days

29
Q

Oviduct a.k.a

A

Fallopian tubes
Uterine tubes
Salpinges

30
Q

All are short muscular tubes with one end opening to the peritoneal cavity;
one end communicating with uterine cavity

A

Oviduct

31
Q

Oviduct function:

A

transport oocyte from ovary to uterus
: provide necessary environment for fertilization and early development of zygote

32
Q

Oviduct Segments

A

Ifundibulum
Ampulla (longest segment; site of fertilization)
Isthmus
Intramural portion

33
Q

Three layers of oviduct

A

Mucosal
Muscular
Serosal

34
Q

inner layer with thin longitudinal folds
Projecting into lumen

A

Mucosal

35
Q

middle layer with inner circular and
Outer longitudinal smooth muscle layers

A

Muscular

36
Q

outer layer with mesothelium &
CT of Mesosalpinx

A

Serosal

37
Q

Mucosal layer

A

simple columnar with ciliated low cells (black) and non-ciliated peg cells

38
Q

Ciliated low cells

A

help transport oocyte to uterus

39
Q

secrete sperm capacitation factors

A

Peg cells

40
Q

Proliferative stage

thick muscular layer
Outer longitudinal layer
Middle longitudinal layer
Longitudinal layer
All smooth muscle layers

A

Myometrium

41
Q

Simple cuboidal
Lamina propria
Secretory glands

Endometrium : Stratum functionale
Stratum Basale

A

Mucosal layer / Endometrium

42
Q

Sec. of uterus in Secretory Stage

A

Myometrium
Endometrium
Stratum functionale
Stratum basale

43
Q

– longest in secretory phase menstruation, which is regulated by Progesterone.

A

S. functionale

44
Q

Menstrual stage

A

Myometrium
Endometium
S. functionale
S. basale

45
Q

Inferior portion of uterus that protrudes into the vagina
Distinct from the body and fundus of uterus
Uterine cervix
mucous-secreting simple columnar epithelium and glandular folds

A

Cervix

46
Q

Epithelium of cervix

A

stratified squamous parakeratinized

47
Q

site of many cervical cancers

A

Cervical-epithelial junction

48
Q

Vaginal Layers:

A

Mucosa
Muscularis
Adventitia

49
Q

stratified squamous parakeratinized epithelium that secretes glycogen; no glands in lamina propria

glycogen – metabolizes lactic acid (via bacteria)
lactic acid – lowers ph & provides protection

A

Vaginal mucosa

50
Q

inner circular and outer longitudinal smooth muscle layers;
No muscularis mucosa
Note: the vagina can be distinguished from esophagus by the absence of M. mucosa

A

Muscularis

51
Q

dense fibroelastic CT
Adheres vagina to surrounding pelvic contents

A

Adventitia

52
Q

highly modified sweat glands; identical in males and females until puberty

A

Mammary gland

53
Q

few lobules
Abundant CT & adipose

A

Inactive Mammary gland

54
Q

simple cuboidal epithelium surrounded by loose CT

A

Intralobular ducts

55
Q

A sect. of active mammary gland
Significant proliferation and development during pregnancy
Abundant glandular lobules
Less CT and adipose tissue
Alveoli and ducts with simple cuboidal epithelium
Secrete colostrum/Milk (yellow) via Apocrine secretion

A

Active mammary gland
