You have no idea how thankful i am for this video! I'm a med student and studying this in physiology. My native language is arabic and not English so my study sheets were quite difficult to understand. But you just made it so easy to grasp more than my physiology doctor managed to! Thanks!!!!!

Why is he so good at drawing

[@uncertifiedlinguist8396]

Because when you understand what you're talking about, you know how to express it best.

​@uncertified linguisСон байгаа шүү дээ. За ар нь салах гэр лүү яах гээд юм байна үү? За яа чиний утсаар залгахаар яадаг юм шиг зүгээр хэд билээ. Утас нь наадах чинь гарахгүй байна аа би гаргах гээд

[@menosproblemos6993]

I liked the video. I would've liked to have yet another example. I get it though. Thank you.
I'm hyper sensitive and can manually release neuro transmitters. I've had some pain in my back and noticed that I had a 'communication blockage' in my brain (some left over defense mechanism, probably from some time when it was necessary). I released it and now my back's a bit better, thanks to your video.
Thank you. I'll have a smoother stride now ❤️
I'll get back to it

[@abhayc576]

How does a cell interpret a message, and take it as a friendly message and not react negatively? What I mean to say is, why do they choose to believe the message relayed from the other cells? And since this is possible, aren’t we capable of somehow creating artificial messages to relay to our cells to have them do certain tasks?

[@afairusputri4604]

Interesting hahaha
Maybe in future we'll find out

[@stillraining2462]

Super good video.

[@Jumanajum_]

Yo you way off topic. @5:48

[@darnosauur]

not at all actually, the growth hormone was used as an example to show how long distance cell-cell communication works: through the bloodstream! He just gave a little background information about the hormone to help us understand
