Omg, I just found this site through google... I have a final this week on histology and I was sooo scared for it because I was so confused! This site is a lifesaver!!!! THANK YOU THANK YOU THANK YOU! You explain these slides 10X better than my teacher ever did! I am so glad I stumbled upon this!
Wouldn't primordial follicles be the only type of follicles present in a fetus?
"Primordial follicles, which consist of a primary oocyte surrounded by a single layer of flattened cells, develop in the fetus and are the stage that is present in the ovaries at birth and throughout childhood." -Is what my book said.
Zona pellucida is present in primary follicles as well, however they don't have a follicular antrum, which the secoundary (antral) follicles have.I hope this info can be useful.
Please i have some questions if u cld answer them for me
how can i identify atretic follicle, vesicular follicle and growing follicle??
i ve searched alot for them but unable to find a proper solution....n i dont remember wht d teacher did say in the lab to differentiate b/w the three.....i ve to label them as well apart from the primordial primary and secondary follicles...please help me and define them for me!!:)
Late Primary Follicle: The Granulosa cells proliferate and become multi-layered(stratified). The secondary (Antral) follicle: Spaces begin to originate between the Granulosa cells. The last stage - Graafian (mature) follicle - is when the spaces are all joined into a big "Antrum", and the oocyte is pushed to the periphery, the mature follicle also includes the surrounding stromal cells (Theca Interna and Externa)
Detailed answer for the debate about follicle names: The oocyte is considered a primordial oocyte no follicle, until the epithelial lining of the ovary invaginates the stroma of the cortex and envelopes the oocyte, creating the Primordial follicle (made of an oocyte surrounded by a layer of squamous looking follicular cells). Primary Follicle: the surrounding follicular cells become cuboidal (now called Granulosa cells) and generate the zona pellucida.
Your videos are great when it comes to studying histology. I have a question though. You say when the zona pellucida forms on a follicle it becomes a secondary follicle, but we were taught that once the antrum begins to form it becomes a secondary follicle. Which is correct? Thanks.
You know that the oocito stages have never quite stuck with me up till today; and therfore MUCHISIMAS GRACIAS for the developmental outlook it realy put it into perspective!!!!
Hey! Congrats on the whole shotgun histology series, it's awesome. I just have one question. I've read that secondary follicles are the ones with the formed antrum, while the graafian follicles are the ones with a lose oocyte in the middle of the follicle... is this true? which is which? thanks!
hei Dr! i want to thank you so much ! cause i understand everything from histology from your movies! realy realy thanks ! best wishes for you! thank you so much!
By the way.. I wanna thank you personnaly cuz It has help me trough my histology lab and I think this is the best way to study at home with the help of our books,
I wanted also to say that the cells that are aroud the ovocyte (in the folliculary liquid can be called CORANA RADIATA and that the CUMULUS OOPHORUS are the cells that "attached" the ovocyte to the ZONA GRANULOSA.
hi wdc very nice video, i wanted to ask u sth about the staining, coz sometimes when histology is complicated i use to memorize slides by their colours is this wrong ????
not sure if "memorize" is going to help, remembering that ALL shades of blue, red, and purple will have tremendous variations in H&E with different labs, days, and techs
i think memorizing colors is best for NON H&E stains like trichrome (collagen green), prussian blue (hemosiderin dark green) and PAS (bright red)....thise are the colors which do NOT vary
Now I understand feelings. Strokeitmuself.

theca interna has a receptor for LH (luteinizing hormone) and makes progesterone and androgens (which are later made into estrogens)
theca externa doesn't make diddly squat
WashingtonDeceit 3 years ago
Hi!!! i wanted to ask u sth about the theca!!!
when are the theca interna and externa produce???
valeriak88 3 years ago
in the secondary follicle. I think. if that's what you're asking
