20
Q

what does the oviduct do

A

transports oocyte to the uterus

21
Q

where is the site of fertilization

A

the ampullary-isthmus junction

22
Q

how lung does fertilization take

A

15-18 hours

23
Q

what captures the oocyte

A

ciliated epithelium

24
Q

what happens in the ovary

A

oocyte maturation and folliculogensis

25
Q

what are ovaries the source of

A

sex steroids

26
Q

in males, where does the blood supply come from

A

periphery - tunic albuginea

27
Q

in females, where does the blood supply come from

A

the inside (medulla)

28
Q

where does spermatogenesis occur in males

A

on the inside (seminiferous tubules)

29
Q

where does folliculogenesis occur in females

A

on the periphery (cortex)

30
Q

what is unique about horse ovaries

A

they are inside out

31
Q

how are primordial follicles organized

A

in clusters (cysts)

32
Q

what are primordial follicles surrounded by

A

squamous granuloma cells

33
Q

do primordial follicles proliferate

A

no

34
Q

characteristics of primary follicles

A

cysts break down
oocytes are surrounded by layer of cuboidal granulose cells
formation of the zona pelucida
irreversible

35
Q

where is the zona pelucida formed

A

primary follicles

36
Q

characteristics of secondary follicles

A

granulosa cell proliferation
formation of theca layers (interna and externa)
blood vessels develop in the theca

37
Q

where are theca layers formulated

A

secondary follicles

38
Q

what happens in tertiary (developing antral) follicles

A

formulation of the antrum
granulosa and theca cells multiply

39
Q

what is the antrum

A

a fluid filled cavity

40
Q

characteristics of the theca externa

A

muscular
innervated

41
Q

what does theca interna produce

A

androgens under the control of LH

42
Q

what do granulosa cells do

A

convert androgens to E2

43
Q

what do preovulatoru (dominant/antral/Graafian) follicles do

A

preparation for ovulation

44
Q

how long does ovulation take

A

less than 2 minutes

45
Q

what is the corpus hemorrhagicum

A

temporary structure formed immediately after ovulation
filled with blood that quickly clots

46
Q

what does corpus luteum

A

high levels of progesterone

47
Q

what happens when fertilization occurs

A

progesterone secretion continues to maintain the thick endometrium

48
Q

what happens when fertilization does not occur

A

secretion of progesterone stops –> corpus albicans
