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

Answer 3

vessels and nerves contained in loose connective tissue

Question 4

4 main layers of the ovary

Answer 4

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

Question 5

rete ovarii

Answer 5

embryonic remnants equivalent to rete testis

Question 6

hilus cells in ovary produce what?

Answer 6

steroid hormones

Question 7

Where is the medulla in horses?

Answer 7

on the outside of the ovary

Question 8

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

Answer 8

1 layer of SQUAMOUS follicular cells

Question 9

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

Answer 9

1 layer of CUBOIDAL follicular cells

Question 10

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

Answer 10

multiple layers of GRANULOSA cells

Question 11

fx of zona pellucida

Answer 11

binds spermatozoa and is necessary for acrosomal reaction

Question 12

cumulus cells

Answer 12

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

Question 13

Difference b/w secondary and tertiary follicles

Answer 13

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

Question 14

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

Answer 14

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

Question 15

theca interna composed of (less important)

Answer 15

epitheliod steroidogenic cells, blood, lymph capillaries

Question 16

theca externa composed of: (less important)

Answer 16

fibroblastic layer

Question 17

follicular stigma

Answer 17

site of rupture during ovulation

Question 18

what does rupture of follicle release?

Answer 18

oocyte, zona pellucida, corona radiata, cumulus

Question 19

corpus hemorrhagicum

Answer 19

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

Question 20

luteinization

Answer 20

hypertrophy, hyperplasia, and accumulation of lipid pigment in CL

Question 21

What happens to CL if pregnancy occurs?

Answer 21

enlarges then degrades to corpus albicans after parturition

Question 22

What happens to CL if pregnancy doesn’t occur?

Answer 22

degenerates and is invaded by connective tissue

Question 23

corpus atreticum

Answer 23

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

Question 24

size of lumen in ampulla vs. isthmus

Answer 24

larger in ampulla

Question 25

type of epithelium in ampulla

Answer 25

ciliated ep.

Question 26

muscularis in ampulla vs. isthmus

Answer 26

thicker in isthmus

Question 27

type of epithelium in isthmus

Answer 27

predominantly secretory cells, some ciliated epithelium.

Question 28

type of uterus in marsupials

Answer 28

duples (two independent uteri)

Question 29

tunica mucosa in uterus =

Answer 29

endometrium

Question 30

tunica muscularis in uterus =

Answer 30

myometrium

Question 31

tunica serosa in uterus =

Answer 31

perimetrium

Question 32

Estrogen and progesterone high or low in estrous?

Answer 32

Estrogen high, progesterone low

Question 33

Estrogen and progesterone high or low in metestrous/diestrous?

Answer 33

Estrogen low, progesterone high

Question 34

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

Answer 34

metestrous/diestrous

Question 35

Estrogen and progesterone low or high in anestrous?

Answer 35

both low

Question 36

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

Answer 36

anestrous

Question 37

nondeciduate placenta and species with it

Answer 37

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

Question 38

Deciduate placenta

Answer 38

• Fetal tissue invades maternal tissue
• Maternal tissue lost at parturition
• Cats

Question 39

cervix

Answer 39

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

Question 40

Type of epithelium in estrus vs. anestrus vagina?

Answer 40

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

Question 41

Epithelium lining alveolar ducts in active mammary gland

Answer 41

simple cuboidal or columnar ep.

Question 42

Merocrine secretions from mammary gland contain

Answer 42

protein, carbs

Question 43
