Saves people lives ?
@@chosarang7039 yeah
Why doesn't you workout to get in shape ?
the way this was explained... beautiful. this video helped me not lose my mind through this confusing cycle lmao
Learned more in these 10 minutes than I did in my embryo class.
LOVED THIS! It really brought everything together into a complete picture! I love the side notes and explanations (ie FH and miotic arrest)... I feel better about my final tomorrow! THANKS!
khan's academy always employ the very best!
did i hear in the introduction that the ovarian cycle is the same as the menstrual cycle?
I'm going into my 4th year of medical school, and this is even helpful for me. Thank you!
Smug much? You will have forgotten this 99 times. The question is, will you brace yourself and study it the 100th time?
and yet you are still here watching the video.
@Sunila Rawal exacly! but I think its better for us right!
literally in love and in awe of this channel. In my last year of clinical embryology and this has helped me a TON ! thank you so much
Thank you SO MUCH. I have an histology exam tomorrow and I needed this so badly!
I'm going to publicly apologize for my handwriting. Being left-handed AND a doctor means I had no hope. Forgive me! 🙏🏼😰
the concept matters not the writing..job well done 😎
From another lefty you've done well my friend thank you for helping
Ur explanation was soooooo awesome that ur handwriting was observed when read in the comment !!!
Love u sir...RESPECT 💓
Thanks man video helped
Such a great video. My professor just lectures and it's hard to understand without these incredible diagrams you've created. Thank you so much for helping me understand this.
well and thanks of your lecture from pak kpk
This is clearer than my textbook. Thank you!
got head bangg while reading ganong...just after few seconds of reading from ganong i opened Khan..then everything got clear..thanks Khan...u r too good.
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
NICE you're amazing.
You're right, granulosa cells are also called follicular cells
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.
sir in follicular phase FSH stimulates estrogen production but not LH
I think this is the simplest, most straightforward video I've even seen on ovarian cycle. Thank you❤️
Wow thank you for bringing this alive. Prior to this, it was just so much terminology to learn. Now I can see it and relate it to the lifespan of a woman. Thank you for sharing your talent. Well done.
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!
Thanks for this super comprehensive video! I am a life scientist and a woman and (to my embarrassment) did not know the exact steps that you describe, in detail. That part about the enzyme blew my mind because it is crucial and I never knew :D
I am a curious teenager eager to understand my body and how it works, thank you for this video and the important info I was looking for.
i live in your house
Khan Academy never fail to deliver. Thank you so much
Now for sure I'll pass my test
That "general point" explains a lot lol
lol!
i've never seen anyone with similar handwriting as me, you are a 1st, i swear those are my words written up there lol. Amazing presentation, you KNOW how to teach. thank you :)
Very precious information to understand the ovarian cycle exactly as it is. Thank you very much.!
Wanna learn with me?
We can learn so many things together
thanks for this, big ups
Thank you you saved my hopes for writing my anatomy finals essay
I do not know why I did find this channel before. Is amazing
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.
Oops I talked too early. You should have said it earlier though ;)
10:16 "Cessation of Ovulation" - "The Cause of Menopause"
Sounds like some great album titles.
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! ;)
Thank you so much
You've done the work for free that our teachers couldn't do with a maximum salary.
Beautiful illustrated. ..thanks for sharing
I HAVE A REPORT TOMORROW AND THIS VID HELPED ME A LOT
Thank you so much for making it easier!
WOW wonderfully explained! Thanks ALOT!
eternally grateful!😭
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.
VERY helpful! Thank you!
Ren's Bookshelf oh 🤔😂
Thanks, khanacademy! Very helpful video :)
This was beautifully explained 🙏🏼 thank you!
I wish terms for things hadnt changed, its hard trying to understand this when half of these things have different names now
I appreciate soo much the clarity of the explanation in the video above !!!!!
u have the best videos ever. im a music major stuck in anatomy and this was not too fast. i know how to pause lol. u rock!
I am pissed because my teacher tells a lot of contradictory and false things in class but I have to learn them because only what he says will be in the exam... Even though the information in this video can be sometimes quite different than what I've learned, it still helped me understand more things.
subsequently swept
Man this was so helpful & well explained
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 ?
Thank you so much!! I finally feel like I understand the process.
Khan saves my life
All my questions answered in jx one video
thank you.
0:49
I like starting here.
Thanks for the help.
man huge huge appreciation
Beautifully explained
Thank you so much for this amazingly informative video! This helped me understand so much better. Thank you!
I loved this video! thank you sm, my professor didn't do a good job at explaining it but you did it beautifully :,)
Wonderful explanation never found in any other videos regarding ovarian cycle..
My professor said that zona pellucida and zona radiata form during the formation of the secondary follicle?!?!
btw.... Granulosa cell is the same as Follicular cell.........
Really helpful!! Thanks Khan Academy!!
I kinda wish hearing sal khan's voice tbh
wow what a great job i'm so amazed this is extremely fantastic thanks man i really appreciate keep it up i love it

THANK YOU X100000000
Thanks! beautifully explained
thanks for help
Beautifully put. Thank you so much ily
Very clear and useful!! Thanks for making all these videos! :)
this is really helpful!! thanks a lot
Pls clarify my DOUBT‼️
one dominant follicle per ovary or only one dominant follicle from both ovaries ?
one dominant follicle from one ovary. and the other ovary doesn't produce the egg that month. generally one ovary produce egg per month in the body.
thank you!
Thanks from Egypt from"محمدباسم" 😍
Human creation in Quran
وَلَقَدۡ خَلَقۡنَا ٱلۡإِنسَٰنَ مِن سُلَٰلَةٖ مِّن طِينٖ
We have created man from an extract of clay.
(Surah Al-Mu'minun, verse 12)
ثُمَّ جَعَلۡنَٰهُ نُطۡفَةٗ فِي قَرَارٖ مَّكِينٖ
Then We made him a sperm-drop in a firm resting place.
(Surah Al-Mu'minun, verse 13)
ثُمَّ خَلَقۡنَا ٱلنُّطۡفَةَ عَلَقَةٗ فَخَلَقۡنَا ٱلۡعَلَقَةَ مُضۡغَةٗ فَخَلَقۡنَا ٱلۡمُضۡغَةَ عِظَٰمٗا فَكَسَوۡنَا ٱلۡعِظَٰمَ لَحۡمٗا ثُمَّ أَنشَأۡنَٰهُ خَلۡقًا ءَاخَرَۚ فَتَبَارَكَ ٱللَّهُ أَحۡسَنُ ٱلۡخَٰلِقِينَ
Then We turned the sperm-drop into a clot, then We turned the clot into a fetus-lump, then We turned the fetus-lump into bones and We clothed the bones with flesh; thereafter We developed it into another creature. So glorious is Allah, the Best of the creators.
(Surah Al-Mu'minun, verse 14)
Thanks
Great explanation. Thanks!
BRAVO!! so much helpful!
u r the best sir...
Very helpful! Thanks
6:14 "So you can kind of imagine how you go for 2-4 million eggs when you were born to having zero after 35 years of ovulation. It's not just that one egg you lose at ovulation, you lose quite a few" umm, you mentioned a number of roughly 16 per month. 35 x 16 x 12 = 6720 which would account for roughly 0.1 to 0.3%. No, given your explanation, I can't "kind of imagine" it at all actually.
THANK YOU
Maybe you could have gone into the role of LH instead of menopause.
Thank you 💕 very much
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.
Amazing!
thank you, your videos are helpful
👍🏻 very helpful
Sooooo helpful and even a little fun!
Thank you so much !!!!
Thanks! It helped a lot.
thanx alot , that was really helpfull
What would be the unsafe period are the days near or during?? Is it menstruation or ovulation?
as the oocyte/follicle matures, does it really move in a counterclock wise direction? or this is just a way of showing the different maturation stages in one diagram of an ovary?
Ken Piocnacia Wow You're a good question! :P lol I think it's just the way
Ken Piocnacia The follicle doesn't move in the ovary. The egg will mature and be released in the same place as where it was created. The diagram is just to make it easier to see the various stages of development. also, sorry for responding to this 4 months late.
Amazing
nice work done
