Wow the way college explains it is so difficult to understand. This helped me a TON. Thank you so much!
That’s so true and what’s even worse is the pace they teach at.
Thank you for making this topic wayyyy easier! 😃
this channel is a blessing ... thanks for all of this, it really helped me
awesome this was exactly the information i needed. thank you so much
brief and informative, thanks!
Thanks man , it was hard for me ,but now I know it!
This explanation by you is really helpful.. thnk you so much
Man, this is amazing! Now it's so simple
Loved this, finally understood this!! Also i love your voice
That moment when you realize the guy that made the video was your old 10th grade chemistry teacher
comment i was looking for lol
omg?? i-
Last reply 3 years ago damn
Good explanation, very helpful. thanks!!
Thank you for this video! The lecture material was just sliding off my smooth brain, and this helped it to stick!
you're literally saving my ass, i am about to give an exam on Biology in a few days and you make the process of learning 10x times faster
Most helpful video on this subject that I've found, thank you
Very simple. Thanks!
Clear and to the point. Thank you
Explained better than my book! Thank you so much.
thanks ! good
Omg i was suffering from this information you made it super easy that video did show up to me from heaven thank you soooo much❤❤
thank u! it was so helpful!!!
Didn't mention Hemidesmosomes or Plasmadesmota. Also I would recommend to mention and explain Anchoring Junctions and Communication Junctions.
RanakTv propably in the next video.
Basically, communication and gap junction is the same.
@@hermionegranger3141 Fax
Anchoring junctions and desmosomes are the same thing so are communication and gap junctions
Amazing. it is perfect.
so helpful, thank you!
very helpful, thank you!
5 minutes of pure elegance, my squire
thank you so much!!!
so far the best video on cell junctions
Awesome!
Thank you .
Thanks a bunch!! :)
thank you so much! :)
Wow! So helpful :D
thankss
Interesting!
thank you for helping
thank you sooooo much for this video
Thanks
thank you!
thank you it very useful
just a bit of added info: desmosomes bind intermediate to intermediate from one cell to another. and Zonula adherens actin to actin. these both make up the anchoring junction. :D
+WILL BIRD just a more bit of added info : In desmosomes (macula adherens) cells connected by keratin like protein instead of actin. :D
+Just a more more bit of info:- keratin like protein in the zonula adheren forms microfilaments and the actin like protein in the macula adheren forms tonofibrils. :D
Just a bit bit of added info: the thin linker protein filaments extending from plaques in desmosomes that hold adjacent cells together are called cadherins.
This is a little to general
Greg Mac too*
tbh I was thinking the same thing, but now that I think about it its def. better for the video to be like this because now when I read my book is 10x easier to memorize the finer things not mentioned here
wow your explanation is so easy and wooooooow
King!!! ❤️✨🙏
Thanku
thank you
Nice explanation
great video
Thanks soo much
Thank you:)
Are gap junctions permeable like desmosomes or are they water tight in between them?
What is the meaning of stress in these scenarios. ( skin and intestine)
Thanks 👍
some ions can pass through Tight junctions - Magnesium for example. Tight junctions are not completely impenetrable
Yeah, that’s right! Some are leaky and allow certain ions to pass though but the majority aren’t and so they are known as such.
Thanks 🦋
nice
Is this comparable to different cells working together? Like for example cells that are only for liver and cells that are for teeth?
Is our body an ecosystem as well for our cells?
What’s the difference between zonula&desmosome(macula)?
hmm this video very educational. 9/10 stars
thanks u i agree
What’s the difference between spot and belt desmosomes?
Desmosomes is also known as an anchoring junction., that's what it's called in my biology book chapter 4.20
Desmosomes is only a one type of anchoring junction
ok I was about to say, lol. I was gonna ask, "desmosomes, you mean as in "anchoring" junctions, right? Cuz desmosomes are not in my notes for types of junctions, anchoring is." I'm glad to know that's what he means. lol
What type of cell junction in the BBB?
that what I coal it great work😃
call*
zannatul Zan
Can someone tell me what major I need to do this and free research?
What about adhering junctions
Ikrr.
Hi
Adhering junctions are called desmosomes.
@@fckit312 no both are different desmosomes are connected by cytoskeleton and adhering junction by actine microfilaments
Desmosomes : cell to cell adhering
Hemidesmosomes : cell to basement membrane adhering
what about zonula ?
Tight junctions are not water and ion tight
Weakening of junction between cell and trophoblast membrane : how can u break it
desmosomes, you mean as in "anchoring" junctions, right? Cuz desmosomes are not in my notes for types of junctions, anchoring is.
What is in the Greek prefix "hemi" of hemidesmosomes made it different from the desmosomes?
Anyone? Asap!
Easy but not enough
Great overview!
can i give you my tuition instead? tysm
wait so are desmosomes tunnels too?
Uhlaallalalalalalalallalal
i know that sodium and other ions cant flow between cells in intestines cause there are epithelium tissue so ions flow across the cells.
Why don't the water then move in the body from skin?
Hi Khan Academy member just to inform you that this video is not on the App
Why cant this guy be my professor
Audio quality is too much poor
The written words are not clear
anyone else here trying to learn about sql?
they kinda??? really??
Not good as I expected
Great Video! (Jesimiel Millar Fernåndez) 1M981
