The original reason that the epithelium lining the lower urinary tract was called "transitional" is that it "changes" in thickness during, say, the contraction and relaxation of the bladder. Today, it is more correctly called "urothelium"

"I'm trying not to use a lot of ESOTERIC words which really don't matter and which will confuse you..." I had to look up "esoteric" to find out what it meant.

Fantastic primers for histology, as a med student I really appreciate you taking the time to make these and share them with the public! Thanks so much!

proximal so packed with microvilli, it looks like it has no lumen

One year ago i studied this video and got a similar sample at my exam, I succeeded thanks to you but had never come back to say thank you man ! Hope everything s good for you

you, Sir, are a wonderful human being and are certainly enriching the field of medicine with your knowledge and kindness! i have a histology exam coming up tomorrow and could not be more prepared

The audio is out of sync, seems to be ahead of video

Please fix the audio. Thank you so much dr. Minarcik.

At the beginning the slide looks very happy.

In my 6th year of medicine and these videos help a lot! Thank you for your amazing work!

yup, u right, i screwed up, i OFTER screw up, thanks for being a keen listener

Thank you very much for sharing this video, you are making things soo much easier for histology

These videos are all unbelievably helpful

Thank YOU! Now i understand Histology!!! U save my live!!!

Lifesaving! thank you so much!

So nice and simple...thanks a ton!!!

Thank you, your videos were helpful and I passed my exam!

Excuse me professor, why didn't you talk about the medulla?

I really enjoy watching your videos to get an averview and to prepare for exams, they are great!!! Unfortunately this video is out of sync, can you fix that ?

Such amazing video. Thanks sir!

"epithelium" is a generic term used for any flat lining cell such as mesothelium or even synovium

I love this guy.

@Punkomatul Oh? I thought the mesangial cells were sort of the connective tissue of the corpuscle, and that the extraglumerular ones were located in the vascular pole.

The part of the distal convoluted tubule in proximity with the vascular pole is the macula densa, which forms only part of the juxtaglomerular apparatus, no?

great work you help a lot with my slide test final.but why don't you mention the loop of henle in the medulla?

Thank you so much this video helped me alot

@Bahamut2218 yes indeed, the other part is composed of smooth muscle fibres from the arterial walls that have suffered secretory differentiation.

@Punkomatul And those are called juxtaglomerular cells, from what I've learned.

Thank you

Mazing video - But can someone tell me how to spot and tell the difference between proximal/distal tubules?

@Bahamut2218 yeah i belive that's correct. You can also call them extraglomerular mesangial cells if you want.

Love this video as well thanks for sharing with us ;D Blessings

thank you sir

Mesangial cells are visceral, He says that towards the beginning but then calls them parietal near the end.

i agree with you as there is mistake on the end of

@WashingtonDeceit; Harbinger631 is right the audio is out of sync. If you have time can you please fix it? This video is very valuable - thank you!

@Bahamut2218 intraglomerular mesangial cells are sort of a connective type of cell (though note that they're "sort of") from within the glomerule and extraglomerular mesangial cells are the ones at the vascular pole that we talked about earlier....i hope you understand what i mean :)

thank u sir. u really helping

First off I'd like to say your vids are of great help to me. I would just like to remark that the (macula densa?) cells involved in the renin system you refer to at 4:30, are part of the distal (not the proximal) tubule....or I just didn't get it right :-)

This is so helpful, thank you!

the audio is out of sncy for most of the second half of the video

shotgun histology, you champion

edit the video sound is 20 sec earlier than video!!

I think there is a mistake at 4:32 when you mention that part of the Proximal convoluted tubule forms the macula densa. It should be the distal convoluted tubule.

You sir are a legend

Yes, you are correct. :)

I dont know if its just my comp,..but it seems that the timing is off..

MY SAVIOUR!

Thank you for this video. Are the cells that lines the capillaries called ENDOTHELIAL cells rather than epithelial cells. Epithelial cells are usually for protection. Endothelial cells are specialized for the exchange of nutrients and oxygens, and toxins, from the blood. I need this verified. Thanks. Brilliant Lecture.

this video should definetely be re-recorded...

Really good that u r making these movies! BUT on this movie the voice does not synchronize with the movie... :)

The sound is a little bit off, right?

At scale of one to ten you are awesome 17! :)

Its worth watching this video but still i don't get how to differentiate proximal and distal tubules. Both looks similar.

Painless kidney

perhaps you can listen to some mccain speeches?

very very very good

university of iowa's virtual histology website

holla to all kcl students with the spot test tomorrow

this is so confusing. :( im lost. its not synchronized i dont think. because i dont see anything youre talking about.

Hi all RSU international students reading for tomorrows Histology Colloquium

voice is faster than the mouse.. i'm getting confused

sound isn't synched with the video... unfortunately :(

Sen adamsın türkler likelsasın

2:23-3:04

thanx but voice out of sync

I love you, you're the best, can I have your babies?

The sound isn't synched with the video, which defeats the purpose of the video. If that could be fixed this video would be amazing.

If you need some help before an exam just google histology.be and you will find an electronical microscope. A big thanks from belgium

stop smoking weeed!!! ur mixing too many stuff :D

you must be blind then

mr your voice is so so so so so looooooow please fix it.thank you.
