I went over the first video I believe... I forgot the title of it but it was identifying epithilum cells and the different layers and shapes of them. I watched it once while getting ready for work and was easily entertained and captured by the way you talk and how you present the work. On my lab day today, I remembered vividly about the video and I was able to answer questions of my lab today correctly! All thanks to your videos! Thank you.
I really hope you’re still teaching. Thank you so much for this, every professor I’ve always had teaches this like it’s common knowledge like oh that’s obviously adipose why would you confuse it for simple squamous but you take the time to explain the differences, thank you. Your videos made most of it click for me.
Thank you so much for this vid!! This morning was my first lab exam and I passed with a 84!! Your vids made me understand Epithelium tissue more😊😊 look forward to watching more of your vids I have two more lab exams left !!
Thank you for giving us an amazing histology lecture
After watching this lecture I cleared all of my queries and easily identify epithelium types 😊
The best video out there about this topic!! Good examples and nice explanations regarding transitional and pseudoestratified :))

thank youuu your videos helped me get a 92 on my exam
Thank you so much!! This helped so much made it much easier to break it down and understand!!
You theeee best
Histology has been made easier ❤️❤️❤️❤️❤️❤️❤️❤️❤️
Thank you so much for this video two days later I have first lab exam and now I know everything about epithelial ❤❤❤❤❤ thanks so much
Great examples- thank u! 😊
You're a great teacher, you've taught me a lot on this. None of it my teacher actually put on the test, I've never seen such bad images in my life and it was on a computer. But I actually learned here
I'm glad that you see the value in learning even when it doesn't necessarily help you on your exams! That attitude will help you go far
Thanks very much 🎉🎉🎉
thank you so much for this ! i feel more prepared for our histology course next semester !
I'm happy to hear that! Good on you for getting a head start. I've got two histology playlists if you're interested in learning more: basic histology: ruclips.net/p/PLBM7jL93Kc2RFon6AxyVIeoAMtp0Ci13u

Yes, thank you I’m so glad I found this video and I passed all your questions so woot woot. This should be a breeze on my exam today.
Good luck on your exam! Hope you get the grade you want
I gotta say, I LOVE your passion for this topic. Your tangent had me arguing against Davidson and nodding my head in agreement like we're gossiping haha!
I'm glad someone appreciated my tangent...normally I just stick to the facts but I was feeling spicy that day 😆
This was really helpful, thank you so so much💕
Hi @anatomyhero do you have any videos on the cell cycle and mitotic cellular division? If so please tell me where I can find it. Thank youuuu
Sorry, not yet!
I have learned a lot
You are the best
Thank you so much for this video 💃🍾
Thank you this really is helpful 👍🏻
In time for my morning exam 😢super scared
Good luck! I hope you get the grade you want...and if you don't...don't give up! Almost every student can ace anatomy exams once they figure out a good study technique! (I have a million and one tips if you ever need them)
Same here 😅
@@AnatomyHero hiii i just wanted to update, i passed my histology exam specifical thanks for your wonderful videos😭video on blood really saved me this was the question i got in the slide test. helped me identify leukocytes like a Pro! my professor was super impressed!
@@marzieshojaat2494 hooray!!! Go you!!!
hahaha same😂
Thank you so much it was really helpful.. was having hard time in differencienting but not anymore 🤗🤗🤗
Glad it helped!
I thought question 16 was stratified cuboidal because of the circle nuclei and multiple layers. Can you explain how it's traditional a bit more please? Thank youuu
Look at the shape of the open space in the center, If this were stratified cuboidal it would be closer to being a circle. It's not a circle because the epithelium is sort of folded/collapsed...and that appearance is because transitional epithelium is designed to stretch. That particular example is the ureter (which connects the bladder to the kidneys) And when urine is passing through it those folds unfold so that the open space in the center is bigger which allows more urine to flow through.
Hope that clears it up! If you're having a hard time understanding what I'm saying try taking screenshots of the examples of stratified cuboidal and the examples of transitional and put them side by side for yourself.
@@AnatomyHero Thank you so much! That helps alot :)
Question 16 at 16:23 - I got transitional mixed up. I thought it was stratified cuboidal. How do i tell apart?
I get asked this so often I made a video about it: ruclips.net/video/tM1d2mqCHd8/видео.html
Let me know if you still have questions after watching it!
Thank you!
how can we differentiate between transitional and non- keratinized stratified squamous epithelium???
Stratified squamous cells are flatter (the ones near the open space, at least). Sometimes it's helpful to get multiple examples of tissues that you are getting mixed up and look at them side by side.
Hope that helps! I do have another video with more examples if you want to try it! (If you go to my playlists you'll find a histology playlist)
@@AnatomyHero ok thanks
The transitional cells - looks cuboidal or circular and looked layered. I get confused thinking its stratified cuboidal
Well my friend, this video is just for you... I'm pretty sure I have a comparison of those two tissues in here, please let me know if you're still confused ruclips.net/video/tM1d2mqCHd8/видео.html
Love your videos, they are super helpful! I have an easier time with lab and I practice with examples like these but I have a hard time with retaining all the information with lecture.. any tips for studying techniques?? Thanks in advance!🙂
I have a thousand and one tips... It's easier when I'm sitting down with a student because then I can hear more about what they're already doing and also kind of figure out how their professor functions... But I'll give you my best general advice of common things students aren't doing.
1) If you do not have a physical copy of your textbook, get one. Cheap copies of any textbook can be found if you get an older edition. Bookfinder.com can be helpful in this. (At least in the us, not sure about elsewhere)
2) Look for language patterns and learn word roots as you notice them. If you see the same letter combination multiple times across several words you should suspect it has a meaning, so just Google it. (Ie you see cytoplasm, chondrocyte, osteocyte, myocyte, google "cyt word root" and you will find that cyte means cell. Once you learn enough you will see a giant word but automatically know what it means because you know all the roots!)
3) If your professor provides a PowerPoint, print it out ahead of time, And if it's provided to you as .ppt file (rather than a PDF) print it out so it's three slides per page with the lines for notes on the side by opening it on a Windows computer in PowerPoint and changing the settings from the print menu
Sometimes you won't be able to see every picture but that's usually okay because generally professors use pictures from the textbook they are using so you can just have your textbook out while reviewing the PowerPoint.
4) Avoid procrastination by organization. This applies to a lot of things but it especially applies to notes. Students will spend ages making really pretty notes but that's not necessarily helpful. You want to spend the least amount of time possible... So for me I would print my professors PowerPoints and write additional notes on that because the bulk of the information would already be written in the PowerPoint.
I would take additional notes off the PowerPoint to help me better understand processes or organization (For example, If I was learning about tissues I might on one page write all four families, the family members in each family, and then characteristics that help differentiate muscle from epithelium from connective tissue... Because that would be something that was in the PowerPoint but spread over multiple slides and putting it in one place helps you see it better)
I would also use my PowerPoints sort of like a flashcards when it made sense. For example if all the types of one type of cell were listed on a slide I would just cover the slide up and then recite all the information I could remember.
I would also use my own notes in this manner.
5) When moving through topics in anatomy, realize that you're not going to learn in a straight line, meaning that it is going to take several times going through something before you will see the picture. Your first time going through something try to think that you are looking for the characters and settings so that you can understand the story... Commit yourself to memorizing the characters and relationships between them on your first time through (For example, your first time through bones, you should try to learn the different cells in bones, and the structure of the bone...and then later when you're reading about the formation of bone you will better understand the story because it will be talking about the types of cells and where they are)
6) When I was reading my textbook I would take notes but I wasn't taking notes to keep forever, it was almost like I was creating a glossary for myself that I could look back to as I was reading and learning that day.
When you're writing notes uses few words as possible, be conversational, never use a whole sentence when you can use a couple words.
Never write down something you already know because you're wasting your time.
7) When reading your textbook... Figure out how it's organized and when starting a section look at what the main heading of the section is and then all the sub-sections in that section so that you have an idea of what the main point is going to be. Try not to take any notes until you have read through a section.... If you're reading about something really complicated, it might make sense to stop more often but either way read through once before you write anything and then go back and figure out what was the main point.
Don't hoard details, you're just jotting something down that's going to help you remember the big picture. Think of it like you're building a house... you don't start decorating the living room when you're still putting up the frame. You just want the big outline of what you're looking at and then later you can start adding in details as you need. Many textbooks have summaries at the end of the chapter. If yours does, once you get through a section go look at the summary and hopefully that will cement the main point of what you just read.
8) Consider recording your professor's lectures (If your professor gives good lectures that aren't just reading off the PowerPoint or going on tangents.)
I would record my professor's lectures and then look over the PowerPoint again and then pause and go to the book and read about the topic because the book would add more meaning to my professors words and my professor's word would add more meaning to the book.
9) If your professor gives a study guide, use it last. I think the word study guide should be changed to study check, because it's what you should do when you're all the way done studying and you've learned everything you think you should know, and then you look at the study guide to check to see if you missed anything.
When students start with the study guide they get tunnel vision and they just sort of look for what's on the study guide and they think they have it but nope, they don't got it... And even if they do end up doing well on that test, sometimes they end up with big gaps in their knowledge that comes back to haunt them in later chapters because a lot of concepts are interrelated.
10) Dont underestimate the length of time you should be spending. I would easily spend 20 hours on this class a week.
11) Understand that studying is a series of skills.... textbook reading, note taking, reviewing... and that you get better at the things you do. It's trial and error and always thinking... how effective was what I just did? Am I retaining information or am I putting in a lot of energy without getting anywhere? What can I do differently?
I know that was a bit all over the place but hopefully there's at least one thing in there that will be helpful to you. Have a great day and have fun learning!
@@AnatomyHero Got it! I actually am taking medical terminology too so that helps because I remember the root words from that class! Thanks so much, I will definitely try these tips and see what works for me!
@@Forevertwentyfive I hope you find something helpful in there. Apologies for the wall of text, I have been meaning to make a video on this topic for a long time and I used your comment as an opportunity to begin organizing my thoughts.
Good luck in your studies!
@@AnatomyHero Very good tips, love that you make some time to write that.
Thank you. I like that you mentioned taking ages to make really pretty notes... after high school, I was stuck and didn't know how to write my own notes because my teachers always provided some sort of outline for us to take home and review but we never really got introduced to writing notes ourselves. Now in college, I'm having difficulty "taking notes" I tend to write too much and miss an important topic or I end up writing not enough. I think I am going to try out what you suggested about the PowerPoint and see how that goes for me because I do catch myself in a spiral and overthinking about notes... Am I doing this right? Am I even learning etc.. @@AnatomyHero
On the non-ciliated pseudostratified columnar. (Male rep) u point out the projections, wouldn't that make it ciliated pseudostratified?
Nope, At some point I state that there is cilia and stereocilia, And even though stereocilia look very similar to cilia.. They are not cilia and therefore it is nonciliated pseudostratified columnar.
As best I can tell, the only example of nonciliated pseudostatified that does not have stereocilia (therefore having no projections and appearing non-ciliated) is the fetal esophagus, which I can't even find a picture of (and probably is not available to most students/professors in most universities)
Question 11,I feel it's simple columnar epithelium because the nuclei are oval
You re the best !!!!!!
doesn't simple columnar have cilia when it's from the fallopian tube?
so, only pseudostratified and simple columnar have cilia or stereocilia normally? (except in the fetus)
Yes to everything!
This ex threw me off 2. Pseudostratified columnar normally hv cilia and simple non-ciliated columnar can have microvilli, so how can u tell difference? Cilia and microvilli look the same 2 me under a microscope-
You are the best
Hey. I thought the nucleus of simple columnar was located at the base of tge cell 11:43
Most of the time it is, but this is an unusual example (I am pretty sure it's from a fallopian tube, rather than the gastrointestinal tract which is where it seems like most examples of simple columnar are taken from)
Are all pseudostratified columnar cell shaped?
Yes!
@@AnatomyHero so don't just say pseudostratified and not add columnar?
Yeah, on an exam you would want to say pseudostratified columnar epithelium. Some schools might want you to say ciliated pseudostratified columnar
@@AnatomyHero
Thank you HERO!
Difference between stratified squamous and transitional?
I made this video where I compare transitional to a few other tissue types (including keratinized stratified squamous), take a look and let me know if you still have questions ruclips.net/video/tM1d2mqCHd8/видео.html
I’m getting transitional confused with stratified cuboidal.
Btw awesome vid!
Then this video is for you! If youre still having trouble just ask... ruclips.net/video/tM1d2mqCHd8/видео.html
@@AnatomyHero thank you!!!
You’re a life saver!
I keep getting transitional confused with Squamous
ruclips.net/video/tM1d2mqCHd8/видео.html a lot of people have trouble with transitional...so I made this video where I show multiple examples: ruclips.net/video/tM1d2mqCHd8/видео.html
In the video I compare it to keratinized stratified squamous but if you're getting it confused with non keratinized you need to pay more attention to the shape of the cells at the top. SS always has flat little pancakes at the top.
I get transitional confused with hyalin cartilage
This is my video about cartilage, let me know if you still have questions after you look at this ruclips.net/video/nWJsiEqgwtA/видео.html
@@AnatomyHero thanks so much
Hello
Your videos helped me in the first semester I appreciate that is it possible to upload videos for the digestive system oral cavity part (tooth, tongue ), and lymphatic systems.❤
❤❤❤
I keep getting transitional confused with nonkeratinized simple squamous. Question 16 I thought was nonkeratinized simple squamous
I think you mean non keratinized stratified squamous (because all simple squamous is non keratinized). Stratified squamous has many flat pancake shaped cells close to the top. Transitional has dome shaped cells towards the top. I suggest getting an example of both stratified squamous and transitional and looking at them at the same time...getting multiple pictures of each would be better
Also, here is my video about transitional epithelium.. ruclips.net/video/tM1d2mqCHd8/видео.html
And if you go to my page I just made a new video where I outline the shapes of the cells if you are having a hard time seeing the shapes.
Yes, I meant stratified squamous! Your channel is a life saver - I just had my first exam this morning and it went great :)@@AnatomyHero
Still having problem with transitional
A lot of people do...try watching this video and let me know if you're still confused. ruclips.net/video/tM1d2mqCHd8/видео.html
Also keep in mind that sometimes you might have to use the process of elimination. List all the other types of epithelium in your head and eliminate all the ones you know its not...and usually when it's transitional you'll only be left with transitional.
If there is a specific other tissue you are mixing it up with try and print out multiple examples and look at them side by side.
Tomorrow my exam on it🙂
Nearly bet your life😂😂😂
WE WANT FACE REVEAL
Tomorrow my exam 😢
I hope you get the grade you want!
Tomorrow me too
