Thank you, med school wouldn't be the same without these videos. And at everyone complaining over the years, be thankful that someone is giving you an extra resource. And btw, it's called Shotgun Histology because he's not telling you every little detail but just the major identifying features. In med school, they spend an hour on the spleen. This is 5 minutes... Use it to orient yourself, not to replace your books and lectures.
𝓦𝓱𝓸 𝓮𝓵𝓼 𝔀𝓱𝓪𝓽𝓬𝓱𝓲𝓷𝓰 𝓽𝓱𝓲𝓼 𝓲𝓷 2024 I am reviewing for my final histology practice exam and your video has been incredibly helpful to me. Thank you so much! Sending lots of love from Ethiopia 🇪🇹
SHOTGUN videos are just the best. everytime i don't find a tissue histology on Shotgun, and finds it somewhere else, i dnt understand it, its either the sound or the images are very poor or too much confusing information. but Shotgun videos are soo clear and precise. once i watch this guy's video, everything gets embeded in my mind right away. THANK YOU SHOTGUN, you opened my mind and widened my histology understanding.
Hey Thanks Again!!! you are really great sir.. Putting up all these videos that too on youtube so that anyone can see em free of cost.. Very generous of you.. Thanks from INdia
Thanks to these videos i got myself a great knowledge that made me get 9 out of 10 samples to identify in my microscope test!! Thank u Dr, Greetings from Sweden
@anything4what Every single one of my movies has at least one verbal typo, that is why I have a very hard time listening to my own movies......AGONY!!! A few even have real boo-boos, but please do not tell this to anybody! ;)
I found this video from "What does the spleen do" parody of the "What does the fox say." I am trying to decide which video is better. I think they are both informative and entertaining in different ways.
Hey, I noticed you said that reticular cells are found in all lymphatic organs however, I was under the impression this does not apply to the thymus? The thymus only has epithelioreticular cells and not reticular cells.
@@WashingtonDeceit Do you still teach in Puerto Rico sir? I have applied to medical school there and I plan on attending. I would love to meet you if so. -Samir N.
you mean how to differentiate spleen from the other lymph structures? Spleen has peritoneal layer, but it has NOT the cortex (lymph node and thymus has), spleen has A LOT venous sinuses in parenchyma and has central arteries in the folicles (thymus has NOT the folicles! ). I think this is the most important diff. you can notice just from taking one look at tissues. Others can check this :)
I just wanted to add something. My histology teacher told me it's impossible to find a sinusoid in a spleen slide because when one takes the spleen out of the body sinusoids collapse
the PALS is composed of T-lymphocytes and the lymphatic nodule is composed of B-lymphocytes (as in the lymph node) The term splenic nodule / splenic follicle / Malpighi corpuscle is formed by: central artery + PALS + lymphatic nodule
@hoburton i think malphigin corpuscles was already mentioned but not by name. the central arteries and the splenic nodules make it up right. or here it is mentioned the lymphatic nodules. but. im getting confused about the periarterial lymphatic sheaths. ehere is it? can we actually find it?
jus to let u kno, the duche below really has long hair, hence we call him pubehead, his hair is so special, ive asked the teacher to do a special slide on it, p.s crakin extra revision material! ggoo hk
At like 2:35 did you mean red pulp? Also this video is very helpful, my class just magically expected me to learn histology in two days and identify samples of various tissue they gave me... I think one is spleen but my PAS stain didn't leave all the tiny dark specs, so it looks like this minus all the dots (which I'm assuming are nuclei?), is it possible I have a different organ or maybe my stain didn't work properly?
What is the difference between white pulp of the spleen and a lymph node ? I am a medical student and i got this question on my histology oral exam and didnt actually know the answer... could you please help ?
smriti BP not much difference histologically. Both are secondary lymphoid follicles. Blood flow and drainage patterns are different, also remember that in a lymph node the secondary follicles are subcapculsr, i.e., cortical. Imho, the question they gave you was very stupid.
Hi. I´m a portuguese medical student so sorry for my bad english. You're videos help me a lot but on this video I think that you made a mistake. when you say that the sinusoidal area was the white pulp (at 2:36 min) which is the opposite of what my atlas book says "Wheater's - Functional Histology". Thanks a lot for all the videos.

You are a wonderful wonderful person for doing this!
We thank you, from Romania!

hope, u r absolutely RIGHT!
in fact, right after I made the movie, i said....
"shit"...i shudda said sumpin about PALS!
your histo teacher is good!
You are the best! Thanks a lot Dr

Amazing video.
I do think you misspoke around 2:40 when you called that white pulp. That would be red pulp, no?
probably
You are probably correct. Thanks for listening carefully.
Amazing walk-through the Histologi of the spleen ! Thanks.
Thanks to these videos i got myself a great knowledge that made me get 9 out of 10 samples to identify in my microscope test!! Thank u Dr, Greetings from Sweden
thank u for these videos. such a tremendous help in med school. wish i could thank you in person when i pass

Thank you so much for these videos! They are a great review for my med school exams.
This is med school quality education. Props man.

Are there folicles? Yes - lymph node or spleen; No - thymus. Are there arteries in the follicles? Yes - it's spleen; No - lymph node.
Thank you very much WDC you're a legend, I owe a huge part of my histology education to your shotgun histology/histopathology videos!
thank you so much ..for the first time in my life i am clear about the entire conception
perhaps mentioning the Malpighian corpuscles and the penicillar arterioles? thanks a lot for your help! very detailed explanation!
Hey, I noticed you said that reticular cells are found in all lymphatic organs however, I was under the impression this does not apply to the thymus? The thymus only has epithelioreticular cells and not reticular cells.
Dah Dah probably

@@samirnacer9206 I teach the entire pathology course from October to April.
Thank you very much! I appreciate your work so kuch that i want to tell you I'm really thankful for the full explanation.
Yes i also see that there afew incorrections but the movie, corrects itself later on when we pay attention to the context, great movies!!!!
We thank you very much, sir!!! YOU GOT MY WHOLE RESPECT
i am sure you are right
every movie has some type of verbal boo-boo
when i play it back they make me cringe
but at least 98% is correct
thank you cat!
Thank you very much
You can see them, they dont colaps. In fact if you see a perfused spleen specimen you will see them clearly, formed by stave cells.
Thank you.

Spleen has peritoneal layer, but it has NOT the cortex (lymph node and thymus has), spleen has A LOT venous sinuses in parenchyma and has central arteries in the folicles (thymus has NOT the folicles! ).

@hopemats
PALS = Periarterial lymphoid sheath , not "sheet". (it surrounds the central artriole.)
I just wanted to add something. My histology teacher told me it's impossible to find a sinusoid in a spleen slide because when one takes the spleen out of the body sinusoids collapse
thank you so much, these videos are a truly amazing learning tool :)
Very roughly yes, give or take 10-20 percent!
the PALS is composed of T-lymphocytes and the lymphatic nodule is composed of B-lymphocytes (as in the lymph node)
The term splenic nodule / splenic follicle / Malpighi corpuscle is formed by:
central artery + PALS + lymphatic nodule
I wish you were my histology lector :(
Greetings from Bulgaria!

WashingtonDeceit okay thank you so much :)
at 2:35 it is the area of red pulp, i think you said by mistake white pulp
Exactly, that's what I tried to mean but I expressed myself incorrectly
how would you tell the spleen apart from a just a lymph node or a thymus?
I mean to find one that really looks like a sinusoid, not that there's no sinusoids in the spleen :/ Is it still wrong?
The videos are basic tbh, but still very good videos
Are we able to identify the periarteriolar lymphoid sheath (PALS) on this slide?? thx
Thanks allot sir.
Thank u so much
THANK YOU SO MUCH!!
Where in the spleen can you find sheathed arteries?
+bambi012333 red pulp
so what exactly is the red pulp on this slide? I thought i got it at first but then he said it was trabeculae so now im confused
+Rubin Joseph young man, the red pulp is everywhere, you just have to believe
r u srs
Rubin Joseph there is no joking when it comes to the red pulp
+Majdi Alnassrallah u r my hero can we meet up pls
+Rubin Joseph red pulp is in between the lymphatic sheaths, so everywhere besides the circles of white lymph tissue
sir what are splenic cords in red pulp areas?
thank u sir

I have only 3 letters to say: WOW!!!:D
2020/6/30🌚💔
12ys ago holy crab!
I downloaded for personal use
Nice video but you could have spoken about closed n open theories
get another teacher
pulp arteries, trabecular vein, and artery, venous sinus, marginal zone,
yes there are lot of thing that u didnt mentioned
Good, but you don't identify any cell types...
