|
Mesovarium
|
peritoneum extending from the broad ligament of the uterus that holds ovaries in place
|
|
|
Germinal epithelium
|
covers the ovary and is a layer of low simple cuboidal cells arising from peritoneum
|
|
|
dense irregular collagenous connective tissue layer located immediately deep to the germinal layer
|
tuncia albuginea
|
|
|
small central region of the ovary consisting of highly vascularized, relatively loose connective tissue
|
Ovarian medulla
|
|
|
primary germ cell that develops after the 1st month of gestation
|
Oogonia
|
|
|
Primary Oocytes result from
|
FINAL mitiotic divison of hte surviving oogonia
|
|
|
Primary oocytes begin meiosis still in the fetus but are arrested in
|
prophase of hte 1st meiotic division
|
|
|
Primary oocytes are contained within follicles until
|
late Graafian follicle stage
|
|
|
Unilaminar primary follicle
|
primary follicle with 1 layer of cudoidal follicular cells
|
|
|
Multilaminar primary follicle
|
primary follicle with 2 or more layers of grandulosa cells
|
|
|
follicular cells proliferate and form multi layers around the primary occute at this point the cells are called
|
granulosa cells
|
|
|
granulosa cells are joined by
|
desmosomes and gap junction
|
|
|
zona pellucida
|
acidophilic refractile layer that develops between the oocyte and follicular cells
and is composed of glycoproteins |
|
|
_____ on the oocyte and _____ of the follicular cell extend into the zona pellucida and form gap junctions with one another
|
Microvilli
Filopodia |
|
|
Theca Interna
|
forms from the connective tissue immediatley surrounding the basal lamina
-HIGHLY vascularized with sterioid-secreting cells |
|
|
Theca Externa
|
connective tissue layer surrounding the theca interna
|
|
|
follicle is considered a secondary follicle as soon as
|
fluid filled cavities appear between the proliferating grandulosa cells
|
|
|
lies immediately outside the zona pellucia and is the 1st single layer of granulosa cell surrounding the oocyte
|
Corona Radiata
(remains with the oocyte at ovulation unlike the other granulosa cells) |
|
|
Liquor folliculi
|
fluid filling the spaces between granulosa cells of hte secondary follicles
|
|
|
Antrum
|
relatively large fluid filled space that forms when the smaller cavities of the secondary follicle unites
|
