OMG He gives free lectures and thanks us for allowing him to make that point.

hello Dr even after 8 years your videos are still reaching new medical students like me and i want to thank you very much for saving my histology and pathology in medical school. you are amazing

Little tip to make this video even more perfect ; The T cells on the cortex are mainly immature thymocytes along with macrophages which engulf those T cells which are marked for clonal deletion worths mentioning that the cortical capillaries in the cortex have the blood-thymus barrier . This is while the T cells in the medullary part of the nodule are mature .

Thank you very much, the excellent Dr. Minarcic. I pray to God to reward you for your goodness with the best reward in this world and the hereafter, much better than money.

Amazing. This simplicity is just what I needed.

Thank you very much Professor! I'm having a histology exam this week and your videos had totally saved my life! :D Bless you sir!

Your videos are a great help! I am a visual learner, so this enhances my book reading A LOT. I thank YOU very much!!!

Many thanks from Sweden as well. I actually understand after seeing these videos.

Even the Faculty of Medicine and Surgery in Pavia, Italy, "thanks you VERY MUCH" for these videos! You are just great, sir!

I agree, the blood-thymus barrier is pretty important, as it practically saves our life. Still, great video.

Thank you so much Sir, you are the best!! you explain everything in 3-4 minutes, which if not i have to read about in a book for half an hour!! you sir, are a genius!

these videos are amazing, thank you very much

Thank you so much you have done a great job with these videos! I am in med school and videos like this are very helpful for us students to understand

your vid/explanation combo saves me so many hours! =D

thank you so much!! these are awesome!! great for exam revision!! keep up the good work!

Thanks man, your stuff is excellent. Please feel free to post longer, more in depth descriptions of these organs. Histology experts are few and far between, and to be honest, pretty busy people. So nice to get some insights and clear explanations of what's going on. Have you thought of doing comparative videos of infected versus non-infected lymph nodes, or at least progression of lymph nodes during disease (i.e. histology at different time points as the lymph node swells)?

May you live long such people like you a rare. May you receive many blessings.

Informative and helpful as usual. If only my lecturer was this helpful!

Thanks a lot! Great visual review for histo!

i wish we would have that great proffessors as You at our faculty, everytime i understand the organs very well with your help!! SO THANK YOU VERY MUCH!!

Thanks!!! very helpful!!!! i have two exams with histology next week so this is gr8!!!!!

Thank you so much for making this video

just had an oral exam.you saved my life!

Sir you are a legend

Awesome, great info.

Thank you!

THIS IS AMAZING !

Thank you !!

well done ! they should show your videos at each histology department before going to the practical part!

Perfect! Thanks a lot :)

Great info ... Expect a great intro on thymus histo, its as title says, "shotgun histology thymus" ...

@pamelas38 i think you are right ERCs and RCs are of different origin. ERCs don't make reticular fibers, they just have dendritic extensions, while RCs secrete type III collagen.

Thank youuu !!!

video is very helpful :) thank you! but, just one thing... the cortex is made of epithelial reticular cells too (type I, II, III). Thank You one more time!

so helpful for exams thanks for posting!!

Doesn't thymus not have reticular fibers?

To note: the cells pointed out are NOT reticular cells which produce reticular fibers... they are type VI epithelioreticular cells which produce interleukin that help with the differentiation process of the immature T cells (tested to see if they recognize antigens) these epethial reticular cells are what make up the Hassals Corpuscle

good job!!

WHY DID I NOT KNOW ABOUT THIS EARLIER!!!!!

thanks a lot sir

sorry that is way over my head, but i have always admired people who study the REAL core of immunology rather than take thinhs at face value, bravo to you! i think this B/T hype has been way overdone over the generations, and somebody should take a new look. A wise man once told me that the letters "B" and "T" are the first and last letters, respectively, of a very common english cuss-word, which i'm sure you'll figure out very soon

For a 1 mark question, if asked which lymphoreticular organ lacked a lymphoid follicle, isn't the answer the thymus? Some sources refer to it as a "follicle" but as you say, it's more divided into cortex and medulla

thanks !

Great❤

We should thank YOU sir for saving our lives

you made my day ttc! wdc

this helps a lot for revision of histology! thank you very much!! too bad youtube subtitles aren't completely true (madonna instead of medulla hahah)

They are not reticular cells but they are epithelioreticular cells.

thank u

Please tell me are you on facebook. I would love to join you there and actually thank you very much. You really saved me from the practical torture.

Isn´t the thymus stroma made of epithelial reticular cells, not just reticular cells? I am not sure if this is not only some language difference :-)

Aren't there also in the cortex cortical epithelial cells besides lymphocytes T?

king

Not stroma, but parenchyma is made of epithelial reticular cells, you are right :)

that is correct epithelial reticular cells not reticular cells like he said... I was wondering the same thing!

paramount! !!!!!!!!!

ily

i hope he saves me too:)

Thymocytes are T Lymphoblasts not Lymphocytes. Great Video
