Flashcards in Lecture 02: Reproductive Anatomy (Pozor) Deck (55):
1

ovaries produce 2 main things

gametes and hormones

2

female env. for fertilization and development of embryo

oviducts

3

what events occur in uterus?

sperm transport, embryogenesis, attachment of the conceptus

4

what secretes mucus during estrus?

cervix

5

What produces cervical seal during pregnancy?

cervix

6

female copulatory organ

vagina

7

Position of ovaries in cow vs. mare

cow's ovaries are closer to uterine body

8

cow or mare has shorter body of uterus?

cow

9

female repro tract precursor

paramesonephric duct

10

which species has complete fusion between uterine horns and body of uterus?

primates

11

vestibulovaginal ring in cow vs. mare

prominent in mare, almost absent in cow

12

where does ovulation occur in equines? ***

on surface germinal epithelium, which is present on the OVULATION FOSSA only ***

13

where does ovulation occur in non-equines? ***

anywhere on surface germinal epithelium (covers almost whole ovary) ***

14

In equines, the majority of the ovary is covered by what tissue? **

mesothelium (aka peritoneal layer). Ovulation does NOT occur here **

15

bicornate means

two horns

16

Which species are bicornate?

mare, cow, bitch, queen, sow

17

Which species has septum in their uterine body?

cow

18

which species are bicornate with poorly developed uterine horns?

mare, cow

19

which species are bicornate with highly developed uterine horns?

bitch, queen, sow

20

which species ha simpex uterus? (no uterine horns)

primates (COMPLETE fusion of the paramesonephric duct)

21

which species has CONCAVE shaped uterus? **

mare

22

which species has CONVEX shaped uterus? **

ruminants

23

which species has CONVOLUTED shaped uterus? **

sow

24

which species has STRAIGHT shaped uterues? **

bitch

25

How does distance between ovary and oviduct change closer to ovulation?

Gets smaller via utero-ovarian ligament so oviduct can "catch" ovulated oocyte

26

Type of tubouterine junction in cattle

Type 2. Small ligament prevents backflow from uterus toward the oviduct/abdominal cavity by keeping the tube bent

27

Type of tubouterine junction in cat/mare ***

Type 8. tubouterine junction protrudes into tip of horn of the uterus and there is a sphincter called the OVIDUCTAL PAPILLA ****KNOW

28

broad ligament

suspends uterus. A continuation of peritoneal fold

29

mesovarium

sheet of tissue that hold the ovary

30

plasmentome =

caruncle + cotyledon

31

ovarian bursa in sows

surrounds ovary and is made from mesosalpinx

32

which species has longitudinal folds in the cervix?

mare

33

cartilaginous rings in cervix have what kind of epithelium?

simple columnar and ciliated columnar ep.

34

epithelium in cranial vagina

columnar epithelium

35

epithelium in caudal vagina

stratified squamous epithelium

36

interdigitating prominences of cervix

zipper like muscular fold of tissue in cervix that keep it closed

37

which species has pointed dorsal commissure and rounded ventral commissure on vulva?

mare. ALL OTHERS = opposite

38

2 main things produced by testes

gametes and hormones

39

what events occur in epididymis

sperm maturation and transport

40

vas deferens main fx

sperm transport

41

accessory sex glands main fx

productiono of seminal plasma

42

main fx of pelvic urethra

semen transport

43

main fx of penis

copulatory organ and semen deposition

44

Which species have VENTRALLY oriented tail of epididymis? **

bull, ram,

45

Which species has a CAUDALLY oriented tail of epididymis? **

stallion

46

Which species have a DORSO-CAUDALLY oriented tail of epididymis? **

boar, dog, cat

47

Which species have VERTICALLY oriented testis? **

bull, ram

48

testis orientation in stallion **

horizontal

49

testis orientation in boar, dog, cat **

oblique

50

3 layers of scrotum ***

1) skin (most superficial)
2) tunica dartos
3) scrotal fascia

51

2 vaginal tunics (layer of peritoneum) and their functions ***

1) parietal layer of tunica vaginalis ---> lines scrotal sacs
2) visceral layer of tunica vaginalis --> covers testis and part of epididymi

52

vaginal cavity **

contains serous fluid between vaginal tunics to allow mobility

53

4 layers of testis (superficial to deep)

1) visceral layer of tunica vaginalis
2) tunica albuginea
3) seminiferous tubules
4) mediastinum testis

54

efferent ducts fx and precursor

functional connection between testis and epididymal duct. Precursor = mesonephros

55

rete testis

network of tubules in mediastinum of testis that carries sperm from seminiferous tubules to efferent ducts
