Q

What are the characteristics of primordial follicles?

A

-earliest stage
-present at birth
-most numerous
-inactive until they enter folliculogenesis
-just below tunica albuginea
-primary oocyte surrounded by layer of simple squamous

Q

What are the characteristics of secondary follicles?

A

-central primary oocyte surrounded by zona pellucida
-stratified epithelium leads to membrana granulosa formation
-interstitial cells lead to theca formation
-increase in fluid fragments in epithelium

Q

What are the characteristics of tertiary/antral follicles?

A

-antral cavity that is fluid-filled
-cumulus oophorus and corona radiata present
-expansion of thecal cells
-typically contains one oocyte

16
Q

What is the cumulus oophorus?

A

flattened layer of granulosa cells that the oocyte “sits” on

17
Q

What are the characteristics of mature/graafian follicles?

A

-follicle expands to form a bulge in the ovary
-follicle ruptures and oocyte and corona radiata release into infundibulum

18
Q

Which species does NOT have a random ovulation site?

A

horses; ovulation always occurs in ovulation fossa

19
Q

What is a corpora hemorrhagicum?

A

ruptured follicle filled with hemorrhage

20
Q

What are luteal cells?

A

granulosa and thecal cells that collapse into the ruptured follicle and undergo hypertrophy and hyperplasia

21
Q

What is the corpora luteum?

A

formation of luteal cells during fertilization and implantation

22
Q

Which hormone is produced by luteal cells?

A

progesterone

23
Q

What is the corpora albicans?

A

scar-like structure resulting from the degeneration of luteal cells when fertilization does not occur

24
Q

What are the characteristics of follicular atresia?

A

-degeneration of follicles
-can happen at any stage
-eventually entire follicle is resorbed

25
Q

What are the parts of the oviduct?

A

-infundibulum w/ fimbriae
-ampulla
-isthmus

26
Q

Which type of epithelium is found within the oviduct?

A

ciliated epithelium (moves oocyte)

27
Q

How does the amount of muscle present change within the oviduct?

A

more muscle as the oocyte moves towards the uterus

28
Q

What are the two layers of myometrium in the uterus?

A

-outer, longitudinal layer
-inner, circular layer

29
Q

What is the stratum vasculare?

A

layer of nerves/lymphatics/vessels between the muscle layers of the uterus

30
Q

Where are the endometrial glands located?

A

within the lamina propria of the endometrium

31
Q

What are caruncles?

A

-site where the placenta attaches in cattle
-highly vascular with no glands

32
Q

What are the characteristics of the vulva?

A

-consists of vestibule, labia, and clitoris
-vestibular glands associated with vestibule
-labial portion is folded skin
-clitoris is analogue of penis and contains erectile tissue

33
Q

How does the estrous cycle impact the endometrium?

A

increased progesterone during diestrus causes endometrial growth

34
Q

How does the estrous cycle impact the vaginal epithelium?

A

increased estrogen during estrus causes vaginal epithelium to proliferate and keratinize
