Female Repro Histology Manual

Question 1

when can follicles become atretic

Answer 1

during any stage of development

Question 2

where and what is the tunica albuginea

Answer 2

the tunica albuginea is a connective tissue layer that lies below the germinal epithelium of the cortex in the ovary

Question 3

what type of epithelium does the cortex of an ovary have

Answer 3

cuboidal germinal epithelium (but there are no germ cells)

Question 4

where is the cumulus oophorous and the corona radiate found

Answer 4

the cumulus oophorous is in tertiary follicles and the layer nearest to the oocyte is the corona radiate

Question 5

where are cumulus cells derived from

Answer 5

follicular cells

Question 6

origin of theca versus granulosa cells

Answer 6

theca cells come from mesenchymal cells while granulosa cells are derived from follicular cells

Question 7

what type of cells are in interstitial glands and where are they found

Answer 7

cords of epithelioid cells in the stroma of an ovary

Question 8

where are epithelioid cells in the interstitial glands derived

Answer 8

derived from the theca interna of atretic tertiary follicles or from the granulosa cells of atretic primary follicles

Question 9

what ovary persists in the hen

Answer 9

only the left ovary persists in the hen

Question 10

is the medulla in the avian ovary vascular

Answer 10

yes

Question 11

describe the layers of the avian ovary

Answer 11

there is a germinal layer, under the germinal layer is the tunica albuginea with DCT and a stroma with loose CT containing follicles lies beneath the tunica albuginea. there are sometimes ganglia too

Question 12

what develops in avian oocytes instead of antrum

Answer 12

yolk

Question 13

what is the granulosa layer made of in avian ovaries

Answer 13

simple cuboidal cells

Question 14

describe the vacuolar cells in avian ovaries

Answer 14

they have fat vacuoles in their cytoplasm and their nuclei are pyknotic found in the cortex

Question 15

true or false: collections of vacuolar cells in the cortex may be a sign of postovulatory follicles

Answer 15

true

Question 16

where are interstitial glands found in the avian ovary

Answer 16

in the theca externa

Question 17

it is thought that progesterone is produced by membrane granulosa and interstitial cells in avian ovaries

Answer 17

true

Question 18

describe the character of atretic follicles

Answer 18

the oocyte is getting smaller
granulosa cells are multiplying and replacing the oocyte space
scar tissue will replace it
in the bird, the oocyte becomes surrounded by hypertrophied interstitial cells

Question 19

describe the character of the oviduct

Answer 19

there is a mucosa, muscularis, and serosa
there are mucosal folds.
epithelium is pseudostratified columnar
some cells have cilia while others are secretory

Question 20

is the oviduct of the hen capable of great dilation

Answer 20

yes

Question 21

what synthesizes most of the coats surrounding the ovum in the hard-shelled egg

Answer 21

oviduct

Question 22

what does the magnum form

Answer 22

the albumen of the egg

Question 23

what does the isthmus form in the egg

Answer 23

the keratinized shell membranes

Question 24

what does the uterus form in the egg

Answer 24

uterus forms the outer shell, pigment, and cuticle

Question 25

what forms the chalaza and what do they do

Answer 25

infundibulum; chalaza form the position of the yolk in the egg

Question 26

what does the vagina produce in the hen

Answer 26

nothing, but it contains sperm-host glands for storage of sperm to be used for copulation

Question 27

what is the epithelium like in the funnel (open) part of the infundibulum

Answer 27

simple ciliated columnar epithelium

Question 28

what is special about the folds in the neck of the infundibulum

Answer 28

they fold into secondary and tertiary folds too

Question 29

what is the epithelium in the neck of the infundibulum

Answer 29

ciliated pseudostratified columnar

Question 30

what are the secretory cells of the secondary folds in the neck of the infundibulum comprised of

Answer 30

non-ciliated, columnar secretory cells

Question 31

what does the serosa of the infundibulum consist of

Answer 31

mesothelium and underlying connective tissue

Question 32

describe the magnum mucosal folds cell type

Answer 32

pseudostratified with ciliated columnar and secretory (goblet) cells

Question 33

what does the lamina propria of the magnum contain

Answer 33

compound tubular glands which form the albumin of the egg

Question 34

what in the uterus makes the shell of the egg

Answer 34

the tubular glands

Question 35

describe the character of the shell gland in the uterus

Answer 35

longitudinal leaf-shaped folds, ciliated PSCE

Question 36

what is the epithelium of the vagina

Answer 36

ciliated PSCE with mucosal cells

Question 37

what does the vagina open into in the bird

Answer 37

the urodeum of the cloaca

Question 38

what is the epithelium in an anestrus uterus

Answer 38

simple cuboidal

Question 39

in estrus, what are the cells in the uterus

Answer 39

simple columnar epithelium

Question 40

primordial vs primary follicle cells

Answer 40

primordial: squamous primary: cuboidal

Question 41

are there nuclei in the zona pellucida

Answer 41

no

Question 42

do corona radiata have to be ovulated

Answer 42

yes

Question 43

atretic cells can help provide estrogen for the surviving cell, T or F

Answer 43

true

Question 44

what happens to the nucleus in an atretic follicle

Answer 44

loss of nucleus
