@guminjrng5610 6 лет назад

One thing during primordial follicles the protective cover that cover the oocytes is follicular cell not granular cell.. later on the growing stage under the infulence of (activin ) these follicular cell proliferated and become granular cell. Hope it helps . Over all animation and video is awesome. Thanks tho.

@savannamoody4870 2 года назад

Awesome video, but a couple issues. Even if a woman ovulates for 35 years and loses 28 eggs per month, that only adds up to about 11,000 eggs. You’d have to lose around 950 eggs/month for 35 years to run out. A woman reaches menopause not because she doesn’t have enough eggs, but because of hormonal changes. Also, twins do not result from double ovulation, but rather polyspermy just before the final meiotic division of the oocyte. Other than that, great video!

@celigarces6473 7 лет назад

I read in textbook primordial follicle = primary oocyte + follicle cells that surround primary oocyte. that's why FSH is called follicle stimulating hormone and not granulosa stimulating hormone

@JihadAlAnsari 5 лет назад

NICE you're amazing.

@JihadAlAnsari 5 лет назад

You're right, granulosa cells are also called follicular cells

when more than one follicle ruptures is it from the same ovary ? is it possible for both the ovaries to take part in ovulation at the same time ?

@bezmitiptip 6 лет назад

ı worship you khan

@JihadAlAnsari 5 лет назад

You failed to mention one of the most important concept is that this cycle occurs to a single follicle in the ovary and that inside of the ovary DOES NOT actually look like this. It is actually composed initially of 400,000 follicles that undergo ALL of these stages and not that oocytes develop at one follicle and magically jump to another and then finally is ovulated as an ovum.

@JihadAlAnsari 5 лет назад

Oops I talked too early. You should have said it earlier though ;)

@jacobgarwin5616 6 лет назад

yo... khan academy needs some specific khan my MCAT videos. I know they have their website with the MCAT section but only certain videos are available for certain topics (i.e. this one is essentially it for ovulation). I would rather have a video that gives the NEED to know stuff for MCAT prep. I will never in my life need to know the "cumulus oophorus" unless I am a practicing gynecologist. Rant over, thanks.

@joaomendes6621 8 лет назад

Nice video! Just 2 things, women are born with 200.000 - 400.000 ovules; and the twins part, it can also happen with just one egg being ovulated. Still, it's a really good video to watch! ;)

@MuhammadAli-nf3nc 4 года назад

I kinda wish hearing sal khan's voice tbh

@tabasdezh 9 месяцев назад

Thanks for the video, but there is a problem with this explanation. At 2:44 you said, zona pellucida forms between primary oocyte egg and granulosa cells, but this's wrong. The zona pellucida does not begin to form from the primordial oocyte to primary oocyte stage. The zona pellucida begins to form during the preantral follicle stage, which is after the primary oocyte stage.
