Digestive System Histology | Review and Practice

This video compares and contrasts the histology of alimentary canal, including esophagus, stomach, small intestine and large intestine and ends with practice questions. The 4 main layers (mucosa submucosa muscularis externa and adventitia or serosa) and sublayers (epithelium, lamina propria, muscularis mucosae, circular muscle layer and longitudinal muscle layer) are identified on each organ. Special features (i.e. villi, microvilli, goblet cells, intestinal crypts/glands, brunners glands, gastric pits and gastric glands) are identified.

I need help in interpretation of a slide anyone

[@UN1VERS3S]

Ma'am you're better than my Histology professor, very detailed, precise and easy to absorb way of teaching. Thank you!

[@user-ho5rv2ev5k]

This is the best histology video I've ever watched. Organized presentation and cool voice, thank you so much.

[@AnatomyHero]

What a great compliment!

[@ellenfox6714]

Your histology videos helped me so much in A&P 1 and now again in A&P 2. Thanks so much!

[@alyssaterry9464]

This is really helpful! I just wanted to point out my professor said there are no Goblet cells in the stomach (how you can tell when you move from the pyloric stomach to the small intestine) so be sure to check what your prof says for some of these!

[@AnatomyHero]

As soon as I read this I went 'Ackk!!' because I know the stomach doesn't have goblet cells...I even have a diagram that shows the stomach doesn't have goblet cells in this video! I'm not sure how that got in my head. Good catch, thanks for bringing it up.

[@SICKTerritory]

Also part of how I remember that Barrett’s esophagus is metaplasia to intestinal epithelium vs gastric :)

[@charlenea6180]

Yeahh, that's usually a trick qstn because there is mucous secretions but its by the gastric glands

[@dalabba]

Thank you so much for your video, you did a great job organizing this video. Thank you for providing value to so many anatomy students, like me!

[@goldenretriever977]

This is the most amazing lecture with so many details and examples. Thank you so much!!

[@antoniab3356]

Nearing the end of my first histology course and watching your videos has turned me into a super star this class. Thank you from UWaterloo!

[@miaonufrak]

have my final lab practical tomorrow. thank you so much for this! histology is tough, but you explained this really well :D

[@ornulusoundeffects6423]

Ma'am you have made my life so easy! May Allah give u a lot of happiness

[@Sarcuh]

This really helped me to revise what i had already learned during lecture :)

[@AnatomyHero]

Glad to hear it! Good luck in your studies!

[@onionlayersed]

This was a nice video, and i feel I'm gonna need to watch it again, I'm finding myself unable to have a picture of, lets say the stomach... It's just, I'm being blank. And when learning, it feels like I'm knowing. But then, I'm not. Overall, thanks for the video, at least it made more sense and clearly explained some of the important features needed to know.

[@AnatomyHero]

What I always tell students is "understanding is not the same as remembering"...making a memory is a process that takes time and requires strategy. I recently made a video about learning anatomical terms, I just made it so it will be right on my home page. Even though it's a different topic you can still apply the basic principles that I talk about (spaced recall, etc) to histology. The basic principles is that you want to try recalling things from memory right after you learn them, and then try recalling them 3-4 times in the same review session. And recall it from memory the next day too, Because anything you learn today, if you don't review it tomorrow... You will forget most of it. One strategy you could use with my video would be pausing it after I explain it and then trying to recall all the things I pointed out... You could also listen to me explain one organ and then go and find other pictures and see if you can point out the same features. (Ideally, use ones that your school or professor has provided you because there can be some really bad/weird histology on Google). You may want to consider making notes, as well. Then when you learn the next organ, trying to remember as much about that as you can... But then when you were done .. try to remember what you learned about the first organ. Every time you go forward, go back. Also, I think getting lots of pictures of the organs printed out and putting them side by side can really help (So you look at all the stomachs and point out how you would know it is a stomach... Then do the same thing for the other organs... And then compare and contrast them to each other) I hope those tips help! Good luck in your studies!

[@onionlayersed]

@@AnatomyHero Thank you so much... And I quote, "Understanding isn't the same as remembering... If you dont review it, you forget"... I just woke up, and these words will be with me throughout my studies, thank you so much, and I'll take your advice📌. ❤😊

[@rachaelcranston8719]

also the muscularis mucosa of the esophagus is not always present/ can be patchy if apparent in the upper esophagus

[@doreencoleman3099]

Very informative. Thank you very much. I learned a lot from your especially how to distinguish between the small intestine (fingers) and stomach (knuckles).

[@Baldwinthefourth-1176]

[@artofkang]

I have an exam coming up soon.. This helped me a lot!!!

[@arsonaleleth4877]

Tank you for taking the time to educate me on this because my histo/classes aint bussin

[@marwane5495]

Thank you, it really helped a lot and no extra/complicated descriptions

[@AnatomyHero]

Glad my approach is appreciated, I do my best not to just give the most simple explanation possible! My theory is if you have the basic outline you can fill in the rest of the details using your notes/textbook

[@miducki]

Thank you so much!!!!11 before watching this video, i saw the vid length and i thought ut was too long and was gonna skip. IM SO GLAD MY DUMBSELF DIDNT MAKE ANOTHER STUPID DECISION. NOT A SINGLE MIN WAS SKIPPED WATCHING THIS VID AND IT WAS SO SO SO HELPFUL. Thanks again for this vid!!! Everyone else dont be dumb like me and watch this vid !!1

[@spicesmiles]

thank you ma’am that was so very helpful before my exam

[@penhorse17]

I would love for you to use a different brighter color of pointer that stands out against the slide colors.

[@AnatomyHero]

I have always been annoyed that I can't change the laser pointer color in powerpoint...and this comment reminded me how much it annoys me...so I googled it and it turns out I can. For all the other PowerPoint presentation settings you can change the color of things (highlighter, pen) right in the presentation mode...but the laser pointer setting is hiding in a submenu! I'm always worried about so many other details when I'm doing these presentations that I never stopped to investigate further...so thank you for taking the time to leave constructive feedback. Very helpful.

[@karamkayal901]

​@@AnatomyHero can you do a video on reproductive system histology

[@AnatomyHero]

@@karamkayal901 I'm pretty good with layers of the uterus and ovarian follicles....for male repro I pretty much only know the corpora in the penis and how to differentiate testes and epididymis. No promises, but I haven't made a new video in a while so maybe I will try to do something on some of that this weekend 😁

[@karamkayal901]

That will help so much , i have an exam on 11/7 🙃

[@andrewcox8807]

The Anus has stratified squamous and its definitely a part of the digestive system. Just a heads up the esophagus isn't the only structure/component of the GI tracts w/ squamous epi

[@AnatomyHero]

That's a good point. I did mention that around 3:00, but it's a long video and for a lot of it I'm more focused on differentiating these four specific organs from each other, so I'm sure at some point I said it in a way that might be misleading if you didn't catch the early bit. I probably should've reiterated it later, so thank you for leaving the comment.
