Awesome! Thank you!

I spent two hours trying to understand this concept and you did it 6 minutes. Thank you!!!!!

this video is awesome, thank you for such a clear explanation !!

Where is the rest of the videos??

Why only colloids because colloids are impermeable and crystalloids (Na*,urea, glucose ect) are permeable that's why they do not contribute much in maintaining the osmotic pressure

Loved your way of explaining..... Really enjoyed a lot ❤❤

Very beutifuly explaned,easily understandable❤

Amazing thank you

You’re the best !

❤❤❤❤

👏👏👏

really loved how you use to give some diseases to understand more ,thanks ❤

6:35. Are the sodium ions actually leaking out across the membrane? Coulombic electrostatic force has a inverse square proportion; when myelin adds thickness to the nerve cell wall forcing the intracellular ions further away from the interior the dominos fall nicely. As the myelin degrades and the ions outside start to get closer the dominos no longer fall in a nice ordered state, they might diverge to the cell wall, if the divergence is too much and too many ions accumulate at a thinned section the next node of Ranvier might not receive enough ionic pressure to overcome the 15mV threshold.

4:26. Is the speed of "signal conduction" faster than "ionic conduction"? I am thinking in terms of Alternating current: electrons around metal atoms are sloshing back and forth with no net gain of travel distance while, because of sloshing back and forth, the signal is transferred at light speed. Similarly it seems more precise to say that fast signal is propagated inside the myelin coated neuron faster than ionic diffusion. High concentration at the first node of Ranvier bumps the next cross section of ions, which intern bump the next line; like how a row of dominos toppling while none of the individual dominos themselves have lateral translation. Having charge (ion) concentration shift of 15mV (from -70 to -55mv) is enough to trigger signal amplification when membrane potential shoots up by a factor of 6.333 (95mV/15mV)(think amplifier gain).

great explanation, thanks! now i know what a colloid is too;) paint, milk, fog, etc.

✨️💥👍🙌

you are awesome

Finally i understood this topic, Thank youu

god bless you

Thank you so much for your clear explanation!

you are truly heaven sent because the way you explained this a toddler could understand thannk you it made so much sense

thank you for using the keywords "osmotic" "reabsorbed" "hydrostatic" "filtered" in a full sentence. Helped me understand it better

u saved me

THANK YOU.

Great .. but it is not designed its is CREATED

I don’t get it. Somebody please help. I understand that , 0.9 grams of salt /100 ml is isotonic like the blood. But 5 grams of glucose in spite of the blood having 100 mg of glucose/ 100 ml still isotonic???

Omg 😭😭😭 I love u ❤😭😭😭😭 you are an artist

❤❤

Thank you so so much.

Better explanation than any books ive read! Thank you.

Finally a short video, that is easy to understand. You got a new subscriber 😊.

More videos please 🥺 Do you make courses?

Finally i can visualize it 😭 great help

This lecture is very helpful 😊 Thank you You deserve more💫

I would love it if you did the respiratory system!

Amazing

🤌🥺this video is really helpful Now finally after so many doubts I clearly understand the work of hydrostatic and osmotic pressure
