Shotgun Histology Spleen

[anything4what]

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?

thank you so much, these videos are a truly amazing learning tool :)

here u dint mention about the cords of billroth doc!

[knspirit]

hey this video is awsome dr. i got my histo exam tomowrw this was great revision !! but not sounding offensive i would love to mention that there is also a region in lymhoid organs called the "hilum" through wich the main afferent blood vessel enters the organ, in this case for the spleen ,the splenic artery enters throu hilum, n hilum is not covered by the capsule! i hope i made sense! cuz im just a beginner at histo! thnku agn ur videos r too good

shout out from pakistan!

[hoburton]

perhaps mentioning the Malpighian corpuscles and the penicillar arterioles? thanks a lot for your help! very detailed explanation!

[regenesi]

@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?

[returnoftheunicorn]

how many central arteries are there?

[Gexicon]

Thank you a lot, for your work

[myamotomusashi66]

I have only 3 letters to say: WOW!!!:D

[aluelbaitlover]

thank you very much DR.

God Bless you !

[maxilladragon]

woah!! really nice stuff, got histo exam tomorrow, hope all ids go fine. thx alot frm pakistan. over n out :]

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

[WashingtonDeceit]

get another teacher

[Dexterprog]

I mean to find one that really looks like a sinusoid, not that there's no sinusoids in the spleen :/ Is it still wrong?

[Ivdarrr]

hehe

[metal4livin]

@Dexterprog maybe he meant that sinusoid are obvious before you take the slpeen out of the body. and after you take it out it collapse so you cant really see it. but that doesnt make it NOT having sinusoid. do you get my point?? :)

[Dexterprog]

Exactly, that's what I tried to mean but I expressed myself incorrectly

[bths87]

your professor should know that organs like the spleen or the lungs are filled with reticular and elastic fiers that keep sinusoid or airways from collapsing--they may not be as open after preparation but you can defnitely see them.

[peran920]

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.

[arnabcnmc]

thank u! these videos are awesome!

[joezziee]

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

thank u so much

Thank you.

[azizulsalehudin]

thanks sir,really helpful!

[catarinafpo]

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.

[WashingtonDeceit]

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!

[orthomaslau]

Your comment is correct. At 2:36 min, the author was meant to say the "red pulp".

[hopemats]

Might be worth mentioning the term "Periarterial lymphoid sheet"(PALS) aswell. My histo teacher demanded i knew that term.

Thanks! Love you're videos :D

[WashingtonDeceit]

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!

[hopemats]

she's czech and lets just say her histo knowledge is better than her english, but she sure knows how to thow a test. (not that im proud of mine, managed to write you're instead of your, what a shame)

[KJtheMC]

I also missed the PALS. According to our teachers Periarteial Lymph Sheath must be mentioned. Also, what type of lymphocytes are where. I think T-cells ensheath the central artery. And the term,splenic follice, i did not hear. So a bit confused right now, but thaanks for the video.:)

[Dexterprog]

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

[krofnja]

@KJtheMC T-cells are in the inner region, as B-cells and macrofags are in the outer area... LOVE THE VIDEOS!!:))

[pillsburydourboy]

@hopemats

PALS = Periarterial lymphoid sheath , not "sheet". (it surrounds the central artriole.)

No Cords of Billroth :(.

But thanks, still very helpful!
