Q

which species has STRAIGHT shaped uterues? **

A

bitch

25
Q

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

A

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

26
Q

Type of tubouterine junction in cattle

A

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

27
Q

Type of tubouterine junction in cat/mare ***

A

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

28
Q

broad ligament

A

suspends uterus. A continuation of peritoneal fold

29
Q

mesovarium

A

sheet of tissue that hold the ovary

30
Q

plasmentome =

A

caruncle + cotyledon

31
Q

ovarian bursa in sows

A

surrounds ovary and is made from mesosalpinx

32
Q

which species has longitudinal folds in the cervix?

A

mare

33
Q

cartilaginous rings in cervix have what kind of epithelium?

A

simple columnar and ciliated columnar ep.

34
Q

epithelium in cranial vagina

A

columnar epithelium

35
Q

epithelium in caudal vagina

A

stratified squamous epithelium

36
Q

interdigitating prominences of cervix

A

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

37
Q

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

A

mare. ALL OTHERS = opposite

38
Q

2 main things produced by testes

A

gametes and hormones

39
Q

what events occur in epididymis

A

sperm maturation and transport

40
Q

vas deferens main fx

A

sperm transport

41
Q

accessory sex glands main fx

A

productiono of seminal plasma

42
Q

main fx of pelvic urethra

A

semen transport

43
Q

main fx of penis

A

copulatory organ and semen deposition

44
Q

Which species have VENTRALLY oriented tail of epididymis? **

A

bull, ram,

45
Q

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

A

stallion

46
Q

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

A

boar, dog, cat

47
Q

Which species have VERTICALLY oriented testis? **

A

bull, ram

48
Q

testis orientation in stallion **

A

horizontal

49
Q

testis orientation in boar, dog, cat **

A

oblique

50
Q

3 layers of scrotum ***

A

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

51
Q

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

A

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

52
Q

vaginal cavity **

A

contains serous fluid between vaginal tunics to allow mobility

53
Q

4 layers of testis (superficial to deep)

A

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

54
Q

efferent ducts fx and precursor

A

functional connection between testis and epididymal duct. Precursor = mesonephros

55
Q

rete testis

A

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