What is the "blood-brain barrier"? Does that just refer to the pia mater?

I'm only finding definitions of the blood-brain barrier in terms of arterial walls and permeability. I understand that the blood-brain barrier serves to separate extracellular fluid and circulating blood and lymph from the CSF (cerebrospinal fluid).

But what actually is the blood-brain barrier? Is it some sort of membrane? The pia mater (the soft membrane that lies directly on top of the brain and contorts to the gyri/sulci) seems like it could serve this function. Is it correct to think that the pia mater is the blood-brain barrier?

Any help is appreciated.

Could somebody tell me if the pia mater covers the pituitary gland?

This is kind of a stupid question but I'm using the anatomy coloring book and it looks like I should either color the pituitary gland the exact same color as the choroid process, or the same color as the pia mater and neither of these make sense. Maybe that's not actually a letter C, or maybe the pia mater encompasses the pituitary gland and infundibulum. Can somebody please clear this up for me? My color pencils do not have erasers, no mistakes can be made :)

Viscoelastic properties of the Pia mater?

I am struggling trying to find accurate information regarding the Pia mater. I work with 3d soft printing and I am curious about two things.

What is the general thickness of a Pia mater in a healthy individual (Dura being 0.3mm to 0.8mm and Arachnoid being 35-40 micra)?

Is there any published data that anybody knows of about the respective mechanical moduli of the Pia mater (the closest thing I have been able to find was something published in the 70s which is decently vague).

Any help at all would be appreciated as I have scoured quite a bit.

Pareri despre medicul neurochirurg Leon Danaila?

Vad ca se รฎnศ›elege greศ™it, tot respectul pentru domnul doctor Danaila, personal consider ca ar fi putut face mai mult รฎntr-o tara cu potenta financiara mult mai mare pe cercetare (poate ajungรขnd chiar la un renume mondial atunci, nu doar national), logic, dar asa a fฤƒcut mai mult pentru Romรขnia.

Ma refer mai mult despre viata sa profesionala, performantele in medicina, nu ca om (tot respecul). La ce ma refer aici?

  1. Cu totii stim ca noi ca romani (poate si alte natii) tindem sa ne umflam personalitatile mult mai mult decat le este plapuma;
  2. Desigur ca l-am admirat foarte mult inainte sa dau la medicina (ca majoritatea) si inca il admir, dar acum ca am mai crescut am inceput sa caut cu putin mai mult simt de raspundere performantele sale academice spre exemplu: maretul cordocit, descoperire anuntata de Danaila prin 2011, celula protectoare de la nivelul Pia Mater (o foita de protectie a creierului, din meninge), am cautat pe PubMed (cea mai mare baza medicala de articole stiintifice), am gasit doar un articol scris de el si cam atat, nicio recunoastere internationala, cum ar fi fost normal, atunci cand se descopera o celula;
  3. In multe interviuri are o aroganta aparte, acum sincer pare mult si o aroganta copilareasca, sincera (pe care o intalnesti psihologic de multe ori la batrani, nu in nume de rau), "eu am scris cartile alea, uite unde am ajuns de la Darabani, am ajuns academician, 40.000 operatii de succes - come on, orice chirurg stie ca nu asa functioneaza treaba cu operatiile mai ales in neurochirurgie, lol, 54 de carti, 18 brevete de inventator, 6 premii ale Academiei Romane" etc., veti sti ce zic daca il urmariti; pe langa numeroase faze cu "neurochirurg de renume mondial merge cu metroul" sau chestii de genul, sincer nu zic ca omul are o vina, doamne, doar noi ca popor facem orice sa ii umflam pe acesti oameni, de multe ori mult peste nivelul lor, no offence;
  4. Chiar mai opereaza, dupa cum spune? A introdus microscopul operator in Romania, dar acum pana si la noi sunt tehnici mult mai performante de operat;
  5. Poate unii de aici il stiu pe Sergiu Stoica, neurochirurg la Monza, il dau ca exemplu, tanar neurochirurg de elita in opinia mea, rezidentiat in Franta (foare greu de intrat ca roman), modest, cu aparatura de ultima ora, pe care nu vreau sa fiu rau dar sunt sigur ca Leon Danaila nu stie sa o foloseasca, are o varsta si logic ca nu mai poti invata asa usor.

Ma rog, fiind pasionat de neurologie si neurochirurgie, am facut resear

SERIOUS: This subreddit needs to understand what a "dad joke" really means.

I don't want to step on anybody's toes here, but the amount of non-dad jokes here in this subreddit really annoys me. First of all, dad jokes CAN be NSFW, it clearly says so in the sub rules. Secondly, it doesn't automatically make it a dad joke if it's from a conversation between you and your child. Most importantly, the jokes that your CHILDREN tell YOU are not dad jokes. The point of a dad joke is that it's so cheesy only a dad who's trying to be funny would make such a joke. That's it. They are stupid plays on words, lame puns and so on. There has to be a clever pun or wordplay for it to be considered a dad joke.

Again, to all the fellow dads, I apologise if I'm sounding too harsh. But I just needed to get it off my chest.

Dropped my best ever dad joke & no one was around to hear it

For context I'm a Refuse Driver (Garbage man) & today I was on food waste. After I'd tipped I was checking the wagon for any defects when I spotted a lone pea balanced on the lifts.

I said "hey look, an escaPEA"

No one near me but it didn't half make me laugh for a good hour or so!

These aren't dad jokes...

Dad jokes are supposed to be jokes you can tell a kid and they will understand it and find it funny.

This sub is mostly just NSFW puns now.

If it needs a NSFW tag it's not a dad joke. There should just be a NSFW puns subreddit for that.

Edit* I'm not replying any longer and turning off notifications but to all those that say "no one cares", there sure are a lot of you arguing about it. Maybe I'm wrong but you people don't need to be rude about it. If you really don't care, don't comment.
