Whoever did this voice over, I love your personality so much!!

[@MedicosisPerfectionalis]

Thank you so much, Monica!

I am 46 y-old physician and you teach me a lot thank you you are a master of teaching medicine thank you again I have got electrolytes course before and i experienced some problems with videos but you help me to solve this problem i hope it will not be a future issue because I want more of your valuable courses

[@MedicosisPerfectionalis]

Hey Doctor, Yeah! There shouldn’t be problems next time! Anytime you have any questions or concerns, please send me an email: [e-mail]

(Ans-18), Sodium has fast gates because it's moving under the influence of two gradients (conc. and electrical) whereas potassium moves against (electrical) one and in favor(conc.) of another gradient thus it can be managed easily with slow gate.

[@السيدبلبع-خ2ف]

not correct

[@Paki_997]

At 19:30 the equation is kinda wrong according to gyton well there should be cl- outside in nominator and cl- inside in denominator... ??

[@mrnerd73]

At 18:18 the equation is wrong, you wrote cl-in/cl-out but it's actually cl-out/cl-in . Please correct me if I am wrong

[@Ùpdùlqaðìr]

Youre true but , if youre using that fomula make sure your constant is 60 and not negative 60. so incase you want to make cl in / cl out , you can use a positive constant . but you can see he has used a negative

[@jeinesilva9577]

​@@Ùpdùlqaðìr the point is just about the Cl- (anion). The relation of concentration is the opposite for the cations (Na+ and K+)

[@Ùpdùlqaðìr]

@jeinesilva9577 being long do the way you think is good. Good luck in your studies ❤️

[@yuntao3866]

Hello. In some books concentration of chloride ion in ECF is taken as numerator and conc. In ICF is taken as denominator. Can you explain why?

[@sarahhassan1960]

I really love your humor😂😂😂. I couldn't find the playlist for CVS from the beginning til the end. I just found a couple of videos or is it only that?

And KABOOM! LOVED IT!

[@Mathkhury]

God bless you

[@heshamalbanna892]

Firstly thanks alot for the video its wonderful…. Regarding the goldman’s equation shouldn’t the chloride in and out be flipped … meaning (Conc of chloride out and P of Cl out) as the numerator And the opposite as denominator … since it is -61 Kindly correct me if I am wrong شكرا من طب القاهرة ❤️❤️

[@aub3365]

Yes

[@Countryballs-p8f]

I was looking for someone saying the same thing I was concerned about. Your answer is right, I looked it up in guyton and hall textbook.

[@ashtonsneedensequeira8803]

thanks a lot sir love u as always but can u make videos on cardiovascular system please

[@MedicosisPerfectionalis]

Ok

[@shuttleship]

please do endocrine physiology please

[@MedicosisPerfectionalis]

Coming in a few weeks!

[@shuttleship]

@@MedicosisPerfectionalis hahah thankyou for your nice videos, I'm in 3rd year of my medical school and I don't remember commenting that :p But still if you ever consider replying to this, I've one Q, for me everything seems so detailed and sometimes unnecessary and this stress of exams and all. At the end, I think none of the branches is something I really admire

[@MedicosisPerfectionalis]

So, what’s your question? Can you elaborate, please? Thank you in advance!

[@shuttleship]

@@MedicosisPerfectionalis what to do to find something in this field that I'll enjoy? And what are some other options? (nooo thanks to you in advance

[@danyalahmad2020]

Sir, you said the most excitable part is the node of ranvier but in textbooks and google it says just beyond the axon hillock, in a region called the axonal initial segment. So I am confused, can you please explain it to me which is correct

[@prashantsaraswat-Er-2628]

what is difference between hyaloplasm and cytosol

[@nataliasuchecka5583]

According to goldman equation increase of Cl- inside the cell will cause depolarization, but it is impossible because chloride ion is negatively charged so it should hyperpolarize the cell. Of course Cl-influx will cause hyperpolarization but what if I put the chloride anion inside the cell? Where am I wrong in this deduction?

[@aronianspigonian8589]

When considering Cl- in the Goldman eq, you have to determine the inverse of the standard setup of the equation. To explain further, the concentration outside of the cell will be in the denominator of the equation rather than the numerator as the positive ions are expressed. Vice versa for the concentration within the cell.

where can i find the next video?

[@GregDmochowski]

This is great. But why you speak so fast! (i.e. edit it with no pauses...) I see this trend in many other people's videos, it's like an onslaught! Thank you, no less.

[@MosesKalonje]

You explained too well though you were drunk

[@FMW110]

Is Potassium ALWAYS leaving the axon during resting membrane potential? I mean, there must be some limit, right?

[@MedicosisPerfectionalis]

Remember that you have a sodium-potassium pump.

[@annabelduran3929]

bruh ur so funny. my professor DOES suck at teaching math and thats literally why I dont know what im doing

[@amarthered]

His name is Nernst, not Nernest.

Thank you so much for the correction!

@@MedicosisPerfectionalis Thank you for all the great work! I study in Germany, just couldn't let it go, sorry 🙈
