Q

29
Q

What are the very largest antral follicles called?

A

Graafian follicles

30
Q

What is cumulus oophorus?

A

cloud of granulosa cells which surround cells

31
Q

What is the name for the granulosa cells that are released with the oocyte?

A

coronoa radiata

32
Q

What happens to teh oocyte in the largest Graafian follicle one day before ovulation?

A

completes meiosis I

33
Q

What is different about the completion of meiosis I in oocytes?

A

doesnt produce 2 cells, but 1 cell-secondary oocyte and one tiny polar body

34
Q

What phase of meiosis does the secondary oocyte stop at?

A

metaphase II

35
Q

What happens to the follicle after ovulation?

A

transforms into the corpus luteum

36
Q

What is the function of hte corpus luteum?

A

theca and granulosa cells secrete oestrogens and progesterone preparing the uterus for implantation

37
Q

If no implantation occurs, what does the corpus luteum become?

A

corpus albicans

38
Q

What happens to the corpus luteum if implantation occurs?

A

placental hCG prevents degeneration to maintain progesterone levels

39
Q

How does the ovum move down the uterine tubes?

A

propelled by gentle peristlasis and currents created by the ciliated epithelium

40
Q

Where does fertilisation usually occur?

A

in the ampulla

41
Q

Describe the ampulla of the uterine tube?

A

mucosa is folded and lined with simple columnar ciliated epithleium and secretory cells, surrounded by SM

42
Q

What is the epithelium of the isthmus of the uterine tube like?

A

mostly secretory with few ciliated cells

43
Q

What is the difference between muscle in the ampulla and isthmus?

A

2 layers in ampulla and 3 in isthmus

44
Q

What is the endometrium composed of?

A

tubular secretory glands embedded in a connective tissue stroma

45
Q

What is the myometrium composed of?

A

3 layers of SM with collagen and elastic tissue

46
Q

What is the perimetrium composed of?

A

loose connective tissue covered by mesothelium

47
Q

What are the 2 layers of hte endometrium?

A

stratum functionalis and stratum basalis

48
Q

What is the difference between the stratum functionalis and stratum basalis?

A

functionalis undergoes monthly loss whereas basalis is a reserve tissue that regereates the functionalis

49
Q

What causes the stroma of the uterus to proliferate?

50
Q

What causes the stratum functionalis to degenerate?

A

deprived of nutrients by spasm of spiral artery before mentruation

51
Q

When does the proliferative phase of the uterus end in the menstrual cycle?

A

1 day after ovulation

52
Q

What happens to the glands of the uterus during the secretory phase?

A

glands become coiled with a corkscrew appearance and secrete glycogen

53
Q

What is the difference bewteen the epithelium on the vaginal surface of the cervix and further in?

A

stratified squamous epithelium on vaginal surface to mucous secreting simple columnar epithlium

54
Q

What is significant about the transition between squamous and oclumnar epithlium?

A

transition zone is a common site of syplasia with common beginning of cervical cancer

55
Q

What is the name for the glands of the cervix?

A

endocervical glands

56
Q

What is the secretion of the endocervical glands in the proliferative phase?

A

thin and watery

57
Q

What is the secretion of the endocervical glands following ovulation?

A

thick and viscous

58
Q

What is a nabothian cyst?

A

when outlets of endocervical glands become blocked and expand

59
Q

What are the 4 layers of hte vagina?

A

non-keratinised squamous epithlium; lamina propria; fibromuscular; adventita

60
Q

What happens to the non-keratinized stratified squamous epithium during reproductive years?

A

layer is thicker and cells are enlarged due to glycogen acucumulation

61
Q

What are the layers of muscles in the fibromusclar layer?

A

inner circular and outer longitudinal smooth muscle

62
Q

What lubricates the vagina?

A

mucous from the endocervical glands and fluid from the thin walled blood vessels of the lamina propria

63
Q

What is the function of glycogen in the vagina?

A

commensal metabolise the glycogen to form lactic acid

64
Q

Where does the mons pubis lie?

A

over the subcut fat pad over the pubic sympysis

65
Q

What does the skin of the mons pubis contain?

A

highly oblique hair follicle

66
Q

What types of glands are found in the labia majora?

A

apocrine and sebaceous glands

67
Q

What is the labia minora?

A

thin skin folds that lack subcut fat and hair follicles but los of vasculature and sebaceous glands

68
Q

How far does keratinized epithelium extend into the vagina?

A

to the level of the hymen

69
Q

What is the clitoris formed of?

A

2 tubes of erectile vascular tissue (corpora cavernosa) covered by a fibrocollagenous sheath
