To complicate matters, whenever this card was added to the MCAT deck it wasn’t really tagged by any of the typical primary resources (Kaplan, Khan, etc.). So fairly difficult to tell, on first blush, what the providence of the card was/is.
The only bit we have to go on is a UWorld QID that was tagged alongside it at its origin: 404173.
I have to imagine that the terminology here is fairly low-yield, though couldn’t hurt to corroborate the basic details. I don’t have UWorld access atm, so I can’t do much to verify its relevance, but the note was added by one of our old maintainers so I trust his basic instinct/s.
Also apparently Graaf looked like this (Dutch, of course):
Sorry. Should have mentioned I did the associated UWORLD QID to check if there was anything there and it didn’t discuss the Graafian follicle. I’ll shoot you a DM w/ it. Either way, whatever you think makes sense sounds good! just wanted to tag you since it was relevant to the deck.
But seriously, I think that the spirit of the original version of this card was focusing on the final stage and the emergency of a single, dominant follicle from a field of tertiary (Graafian) follicles. Goal should be to get that concept covered and then forget this forever hahaha
Okay with this solution but the only thing I need clarification on is how many tertiary follicles there are. AMBOSS here says “most secondary follicles become atretic, but usually only one becomes a tertiary follicle”
So would this following sentence make the most sense?
Text:
During the follicular phase, a single secondary follicle will develop into a(n) {{c1::tertiary (dominant)}} follicle, with at atresia of neighboring follicles
Extra:
The term tertiary, dominant, and Graafian are interchangeable in certain resources (AMBOSS)
Per UW source that I provided, 4-10 antral follicles per menstrual cycle. I think the most correct thing is still to revert more towards original but replace “Graafian” with tertiary and put Graafian in extra
" By puberty, only 500,000 follicles have escaped atresia. At menarche, FSH release recruits and stimulates 4-10 antral follicles per menstrual cycle. A dominant follicle emerges , produces estrogen and inhibin, and undergoes ovulation."
