1
Q

tunica albuginea is composed of what tissue?

A

dense irregular connective tissue

2
Q

where do follicles develop?

A

cortex of ovary

3
Q

what kind of tissue and what is contained in the medulla of ovary?

A

vessels and nerves contained in loose connective tissue

4
Q

4 main layers of the ovary

A

1) surface epithelium
2) tunica albuginea
3) cortex
4) medulla

5
Q

rete ovarii

A

embryonic remnants equivalent to rete testis

6
Q

hilus cells in ovary produce what?

A

steroid hormones

7
Q

Where is the medulla in horses?

A

on the outside of the ovary

8
Q

what kind and how many layers of cells in primordial follicle?

A

1 layer of SQUAMOUS follicular cells

9
Q

What kind and how many layers of cells in primary follicles?

A

1 layer of CUBOIDAL follicular cells

10
Q

what kind and how many layers of cell in secondary follicles?

A

multiple layers of GRANULOSA cells

11
Q

fx of zona pellucida

A

binds spermatozoa and is necessary for acrosomal reaction

12
Q

cumulus cells

A

connect membrana granulosa to oocyte in developing follicles (usually tertiary)

13
Q

Difference b/w secondary and tertiary follicles

A

tertiary has follicular fluid formed from granulosa cells, forming an antrum

14
Q

3 kinds of cells granulosa cells differentiate into in tertiary follicles (less important)

A

1) columnar corona radiata (adjacent to zona pellucida)
2) cumulus cells (surrounds corona)
3) membrana granulosa (lines follicular wall)

15
Q

theca interna composed of (less important)

A

epitheliod steroidogenic cells, blood, lymph capillaries

16
Q

theca externa composed of: (less important)

A

fibroblastic layer

17
Q

follicular stigma

A

site of rupture during ovulation

18
Q

what does rupture of follicle release?

A

oocyte, zona pellucida, corona radiata, cumulus

19
Q

corpus hemorrhagicum

A

precursor to CL after ovulation occurs.

  • fills with blood, capillaries invade
  • granulosa cells become granulosa lutein cells
  • theca interna cells become theca lutein cells
  • transition to endocrine gland which produces progesterone
20
Q

luteinization

A

hypertrophy, hyperplasia, and accumulation of lipid pigment in CL

21
Q

What happens to CL if pregnancy occurs?

A

enlarges then degrades to corpus albicans after parturition

22
Q

What happens to CL if pregnancy doesn’t occur?

A

degenerates and is invaded by connective tissue

23
Q

corpus atreticum

A

atretic follicle. Forms from follicles that fail to complete development.

  • oocyte liquifies
  • zona pellucida thickens and folds
  • invasion of connective tissue
  • luteinization of theca interna
24
Q

size of lumen in ampulla vs. isthmus

A

larger in ampulla

25
Q

type of epithelium in ampulla

A

ciliated ep.

26
Q

muscularis in ampulla vs. isthmus

A

thicker in isthmus

27
Q

type of epithelium in isthmus

A

predominantly secretory cells, some ciliated epithelium.

28
Q

type of uterus in marsupials

A

duples (two independent uteri)

29
Q

tunica mucosa in uterus =

A

endometrium

30
Q

tunica muscularis in uterus =

A

myometrium

31
Q

tunica serosa in uterus =

A

perimetrium

32
Q

Estrogen and progesterone high or low in estrous?

A

Estrogen high, progesterone low

33
Q

Estrogen and progesterone high or low in metestrous/diestrous?

A

Estrogen low, progesterone high

34
Q

In which stage of estrus cycle is glandular tissue in uterus the most prolific?

A

metestrous/diestrous

35
Q

Estrogen and progesterone low or high in anestrous?

A

both low

36
Q

In which stage of estrus cycle is glandular tissue in uterus LEAST prolific?

A

anestrous

37
Q

nondeciduate placenta and species with it

A
  • fetal trophoblast tissue interdigitates with maternal tissue but does not invade it
  • maternal tissue NOT lost at parturition
  • Ruminants, horses, sheep, pigs
38
Q

Deciduate placenta

A
  • Fetal tissue invades maternal tissue
  • Maternal tissue lost at parturition
  • Cats
39
Q

cervix

A

valve-like entrance that safeguards the uterus; open during estrus and parturition

40
Q

Type of epithelium in estrus vs. anestrus vagina?

A

estrus: cornified stratified squamous
anestrus: non-cornified stratified squamous

41
Q

Epithelium lining alveolar ducts in active mammary gland

A

simple cuboidal or columnar ep.

42
Q

Merocrine secretions from mammary gland contain

A

protein, carbs

43
Q

Apocrine secretions from mammary gland contains

A

lipids

44
Q

Holocrine secretions from mammary gland contains

A

secretory cells, macrophages, leukocytes
