Oogonia
|
Once primordial germ cells have arrived in the gonad of the female and become differentiated.
|
|
|
Follicular cells
|
Flat epithelial cells orginating from surface epithelium covering the ovary.
|
|
|
Primary oocytes
|
Differentiated from oogonia via mitosis, arrested in cell division of Prophase of meiosis I.
|
|
|
Primordial follicle
|
A primary oocyte together with its surrounding epithelial cells.
|
|
|
Diplotene stage
|
A resting stage during prophase characterized by a lacy network of chromatin
|
|
|
Oocyte Maturation Inhibition (OMI)
|
Small peptide secreted by follicular cells producing the arrested stage in Prophase of meiosis I.
|
|
|
Three stages of maturation experienced by primary follicles.
|
1.) Primary or Pre-antral
2.) Secondary or antral 3.) Pre-ovulatory |
|
|
Which stage of maturation of primary follicles is the longest?
|
pre-ovulatory
|
|
|
Granulosa cells
|
Differentiated from flat follicle cellsa to a stratified cuboidal epithelium.
|
|
|
Primary Follicle
|
When primordial follicles develop granulosa cells.
|
|
|
Theca folliculi
|
Stromal cells surrounding the granulosa
|
|
|
Zona pellucida
|
Layer of glycoproeins on the surface of the oocyte.
|
|
|
What secretes the zona pellucida?
|
Both granulosa cells and the oocyte.
|
|
|
Theca interna
|
Inner layer differentiated from theca folliculi that are SECRETORY cells.
|
|
|
Theca externa
|
Outer layer differentiated from theca folliculi that are FIBROUS cells.
|
|
|
Antrum
|
coalescence of fluid filled spaces between granulosa cells.
|
|
|
Secondary (vesicular) follicle
|
Term for follicle once antrum is created
|
|
|
Cumulus oophorus
|
Granulosa cells surrounding the oocyte
|
|
|
What induces the pre-ovulatory growth phase?
|
Luteininzing hormones
|
|
|
After meiosis I, what is the result?
|
One secondary oocyte and first polar body.
|
|
|
What type of cells are locked into the prophase stage of meiosis I
|
primordial follicles
