Female Repro Histology Manual Flashcards
when can follicles become atretic
during any stage of development
where and what is the tunica albuginea
the tunica albuginea is a connective tissue layer that lies below the germinal epithelium of the cortex in the ovary
what type of epithelium does the cortex of an ovary have
cuboidal germinal epithelium (but there are no germ cells)
where is the cumulus oophorous and the corona radiate found
the cumulus oophorous is in tertiary follicles and the layer nearest to the oocyte is the corona radiate
where are cumulus cells derived from
follicular cells
origin of theca versus granulosa cells
theca cells come from mesenchymal cells while granulosa cells are derived from follicular cells
what type of cells are in interstitial glands and where are they found
cords of epithelioid cells in the stroma of an ovary
where are epithelioid cells in the interstitial glands derived
derived from the theca interna of atretic tertiary follicles or from the granulosa cells of atretic primary follicles
what ovary persists in the hen
only the left ovary persists in the hen
is the medulla in the avian ovary vascular
yes
describe the layers of the avian ovary
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
what develops in avian oocytes instead of antrum
yolk
what is the granulosa layer made of in avian ovaries
simple cuboidal cells
describe the vacuolar cells in avian ovaries
they have fat vacuoles in their cytoplasm and their nuclei are pyknotic found in the cortex
true or false: collections of vacuolar cells in the cortex may be a sign of postovulatory follicles
true
where are interstitial glands found in the avian ovary
in the theca externa
it is thought that progesterone is produced by membrane granulosa and interstitial cells in avian ovaries
true
