Epithelium: the basics - Biology tutorial
HTML-код
- Опубликовано: 30 ноя 2012
- This is a tutorial/lecture explaining the basics of Epithelium Tissue, one of the 4 basic animal (Human) tissues. We cover some topics important for classes such as Biology, Histology, Anatomy, etc.
If you have any questions, don't be shy!! We hope we are able to clarify this topic.
Enjoy!

Thank you so much for putting this up. I have been so stressed over tests and I stopped crying when I came across this. Thanks a million for posting this on RUclips as you are so much better than my professor.
My teacher was making me hate this class but thanks to you im so interested and I finally understand what my prof is talking about in class...thank you so much !! Keep up the good work. :)
Daniela how are your studying now?after 3 years.
BEst video for learning something.thanks
You sound like Joao from Kenhub. My lecturer is french and omg it's a relief to hear things properly without a headache.
Can't believe this has 14 dislikes, it's brilliant information to get started on the subject.
This teacher is made for this. You are bomb man! God bless please keep vides coming. :) Thank you
GREAT MUST WATCH FOR HISTO STUDENTS REALLY SIMPLIFIED
Great explanation and illustrations. I have spent almost an hour reading the text book but still unclear about Epithelial tissue until I saw your video. Thank you for posting.
He break it down in such a way that make my life easy. Kudos
This video seriously helped to simplify everything my professor was lecturing about! Thank you!!!!
First time checking out your channel. Thank you for taking the time out to be a blessing to so many of us. Outstanding video, looking forward to learning more from you.
It's makes me more comfortable, satisfied and very easy to learn
Excellent explanation! Easy to understand.
Thank you so much for making the notes easier!
Gracias, Camilo! That means a lot! Someone asked me a similar question before, it might be confusing. I checked different types of notes and literature and some refer to transcellular transport as, like you mentioned, the transport of molecules by a cell through a cell. Others refer to transcellular transport as what I explained. Either way, the epithelium is able to do both. Hope this helped!
I am glad to hear that this video was easy to follow. You are very welcome! Thank you for writing to us.
Thank you very much for the encouraging words! Glad to have you on board.
best video ever! I love it ..................... thanks sir
I'm studies Clinical pharmacy in Egypt and wanna thank you
very very very very good job ,,,,, Thank you soooooo much !
when I need help I'll call you back
Thanks again !
Thanks for using black colour as background. Nice lecture!
great video, easy to understand. thanks
Great lecture, thanks!!
Epithelium
- Covers body surface
- Lines body cavities
- Forms glands
Functions:
- Secretion
- Selective absorption
- Protection
- Transcellular Transport
- Detection of Sensation
Characteristics
- Packed and contiguous cells.
- Little or no intercellular material.
- Cells are usually joined by specialized cell-to-cell junctions.
- Base Membrane (feature)
- Separates epithelium from the underlying connective tissues.
- It is a non-cellular membrane (protein-polysaccharide rich membrane.)
- Epithelium is an Avascular tissue.
- Nutrients and water reach cells through diffusion.
Types
- Simple squamous (flat/one layer)
- Simple cuboidal (cube/ one layer)
- Simple columnar (column/ one layer)
- Stratified squamous (flat/Different layers)
- Stratified cuboidal (Cube/ Different layers)
- Pseudostratified columnar (Fake/ False/ Column)
- Transitional

Smarty over here 😢
Great lecture ... I learn alot from it ..... Imp points 👌
This was absolutely helpful. Thanks!
thank you for making this video. it helps me alot in study
thanks......good lecture n helpful.....amazing....
My first language is not english and its hard for me to understand my teacher and your video its clear and i can understand everything you say. Its a great video thank you.
thanks a lot for this great job, your explanations are so understandable
Thank you so much for this video. This was very helpful👏🏽👏🏽👍🏻
Thank you! :) I try to keep it simple, like I do when I learn something.
I love you! Thank you! Very well done.
AMAZING thank you so much for doing this...helps ALOT
thanks a million! i try to learning medical english, so useful
Thanks alot man , this is amazing !
man تستخدم للكلش ميانة مو لمدرس😂😂
سوري عالمداخلة
A very good lesson thanks for sharing
very helpful ! thanks
Nice lecture......👍 thank you
thank you!
I just learned something. :)
Holy toast! I just learned something
thank you very much this was a very good explanation :)))
You rock!! Congratulations! :)
thank you very much really i found helpful
thank you sir can i ask you please can you make a video to show us how to Distinguish between Epi. tissues under the microscope
Hope it went well!! :) Thank you for letting us know!
Great!!!!! Thanks po..
Awesome 👏 thank you
Bring on that medicine epithelium test tomorrow I'm ready. Thanks a lot.
nice one explanation love ittttttttttttttttttttttt
thank u
Watching this video at this year because i understand this more than any 5-10minute video
So glad to hear this! 🙌❤
Good job.
very ggood presentation
Thank you!
I can not stop watching all of your videos! Great job guys!
Just a little question: Doesn't the Transcellular Transport involve the transportation of molecules by a cell "through" a cell? You know, like transcytosis. Greetings from Colombia! =D
bestt!! thankuuu!!
Thank you 🌸
thank you soo much
thank you !
THANKS!
Yes!
Got to ask. In the alimentary canal, specifically, the ileum, are the epithelial cells, villi? If so would they then be called simple squamous villi? Also, when you mentioned they don't have a blood supply, I panicked. I've been taught that within the finger shaped villi, lining the mucosa layer in the ileum there is are lacteal, venules and arterioles underneath the surface layer. Am I wrong? Also, in diffusion, this would happen IN epithelium cells as the nutrients are selectively passing through to the phospholipid bilayer and then to the blood stream. Is that right? Thanks in advance
You're welcome! :)
Thank you :)
A link to the intercellular systems would be great. Im always looking for the "detail" vids but only find the overviews
hi ! thanks a lot for your help but can u organize ur videos in one pack anatomy histolgy .... thanks again
You are very welcome! Clinical Pharmacy, excellent! How many years left?
Thanks!!!!!
Im still trying to figure out the difference between stratified and transitional you said for stratified it's different layers and transitional many layers.... isn't that the same thing? how would you be able to tell the difference under a microscope? @TheSalmonellaPlace
That is exactly my intention! Glad to read! :)
Not technically, but I believe I love being one. :) Thank you!
Thx
you sound exactly like the guy in kenhub
Thanks
You’re welcome!
what is the meaning of transcellular transport ??
1- transport of things (as bacteria in airways) along the surface
or
2- selective transport across cells (such as diffusion ,carrier protein mediated transport...etc)
^^last one is written in some books
??????????
oops, i got confused ^-^>>>!
please help
according to some textbooks + wiki ...etc >>> it's the first definition ^(1- ...)
am i correct ??!
hes probably the guy from kenhub :)
Got 5/5 ;)
Test tomorrow huh?
Yes 🙄😂
HHAHAHA:(
Midterm #1
NIIIIICE
It's happend the same with me kkk, I'm brazilian and I understand very mutch in english than with my teacher in my class --'
Transcellular Transport slide: These are Microvilli, right?!
Thank you salmonella
