Q

what kind of glands does the vestibule contain?

A

major and minor vestibular glands

22
Q

what stage is the beginning of endometrial growth?

A

proestrus

23
Q

what 2 things are hapening in proestrus?

A
  1. CL is regressing from previous cycle

2. new follicles are growing

24
Q

what do theca cells produce/ what are they stimulated by?

A
  1. produce androgens

2. stimulated by LH

25
Q

what do granulosa cells produce/ what are they stimulated by?

A
  1. produce estrogens

2. stimulated by FSH

26
Q

what is the period of sexual receptiveness?

A

estrus

27
Q

what 2 events are occurring during estrus?

A
  1. ovulation (in most species)

2. CL develops in this phase (in the dog)

28
Q

what is defined as the period of CL development?

A

metestrus

29
Q

what phase does the dog not have?

A

metestrus (because the CL develops in estrus)

30
Q

what is the phase with the active CL?

A

diestrus

31
Q

what 2 things are happening during diestrus?

A
  1. uterus reaches maximal endometrial gland development and activity
  2. CL regresses toward the end, if no implantation
32
Q

what is pseudopregancy?

A
  1. regression of CL causes increased prolactin
  2. 40-60 days after estrus
  3. mammary development with lactation, behavioral changes
  4. can result in pyometra (infection of the uterus)
33
Q

what is the prolonged period of sexual inactivity?

A

anestrus

34
Q

at what stage of the estrous cycle would the stratum granulosum of the follicle be maximally developed, and estrogen secretion the highest?

A

estrus

35
Q

in what stage of the cycle is the progesterone level maximal?

A

diestrus

36
Q

as FSH secretion from the pituitary slows, what increases?

A

LH secretion

37
Q

what cells secrete estrogen?

A

granulosa cells

38
Q

what are some of the effects of estrogen on the body?

A
  1. sexual receptivity, heat
  2. continuing endometrial growth, increased glanular secretions; maximal edema, hemorrhage and congestion of CT
  3. vaginal epithelium : thick and cornified; clear or bloody discharge
39
Q

what tool can you use to determine stage of the cycle in cats and dogs?

A

vagina smear

40
Q

during what stage does the CL develop in the dog?

A

estrus

41
Q

a smear of vaginal epithelium from which stage of the cycle shouldconatin the most cornified cells?

A

estrus

42
Q

what kind of gland is the mammary gland?

A

a compound gland with large ducts in the interlobuar CT

43
Q

what gland is a modified sweat gland (apocrine and merocrine)?

A

mammary gland

44
Q

what kind of secretory ducts are found in the mammary gland?

A

alveolar and intralobular ducts

45
Q

what kind of epithelium is found in the mammary glands?

A

simple cuboidal to culumnar epithelium

46
Q

what starchy bodies are concretions of secretory material found scattered in alveoli?

A

corpora amylacea

47
Q

what are the contractile cells that surround alveoli and respnd to oxytocin to cause milk letdown?

A

myoepithelial cells

48
Q

what make up the non-secretory, lactiferous sinus

A

gland sinus and teat sinus

49
Q

what is in the stroma of the mammary glands?

A

loose collagenous and adipose tissue (major component of non-lactating gland
**stroma because very scant during lactation

50
Q

what is the opening of the teat that transitions from bistratified columnar epithelium to the skin of the teat?

A

streak canal (lactiferous duct)
