I realize Im pretty off topic but do anyone know of a good site to stream new movies online?

[@lucianoharold8449]

@Leo Amari Flixportal xD

[@leoamari6619]

@Luciano Harold thanks, I signed up and it seems like they got a lot of movies there :) I appreciate it!!

[@lucianoharold8449]

@Leo Amari You are welcome =)

K+ efflux is said to be much greater than Na+ influx (20-100:1). What stops the concentration gradients from degrading? It’s the Na+K+ ATPase right? But the pump moves Na+ and K+ in a ratio of 3:2. So this doesn’t seem to add up. Surely more Na+ must be entering the cell compared to K+ leaving (at a ratio of 3:2)

You are a holistic professor . No one as far as I could see, resembles your condensed recombinant lectures of every single mastery of sciences ! Bravo, you are a great gentleman

[@MedicosisPerfectionalis]

Thank you 🙏

[@ThatsWhy-]

A lecture combined of : pathology, physiology, pharmacology, genetics, biology, chemistry, economy, anatomy... etc, what more should anyone get !!!!

[@MedicosisPerfectionalis]

Thank you so much ☺️

He's just the best!

[@stephanienassar4710]

[@ThatsWhy-]

Thanks from my heart for your efforts that you always exert for humanity. Many Thanks for your mom and dad as well. They are just as great as you

[@ThatsWhy-]

I love your repetition in science! It influxes in my brain .

[@MedicosisPerfectionalis]

Thank you 😊

Best technique......

Thank you so much dear medicosis. I was really feeling desperate without understanding the effects of Potassium on RMP. Reading textbook and hearing lectures didnt help me, but You made it understand in minutes. 🥰🥰. Now I am binge watching your videos

[@MedicosisPerfectionalis]

Thank you so much! I appreciate you!

[@toota1507]

King of medicine 🥺🥺🥺♥️♥️♥️ Thank u so much😢😭

[@MedicosisPerfectionalis]

My pleasure 😇

[@Thecutecherry_tutu]

My friend (who understands what the professor said at the lecture) tried to explain the resting potential and it took two hours and I didn’t understand anything, but one video on medicosis made me see what was hidden

[@MedicosisPerfectionalis]

Wow 🤩 Thank you 😊

Thank you for these videos🙏🙏

[@MedicosisPerfectionalis]

Glad you like them!

[@leeroysunguro1196]

Qsn..is there any way to like your video a million times???

[@MedicosisPerfectionalis]

Thank you so much ☺️

[@germinmedhat8555]

So great videos, Go on Plz we need clinical chemistry videos especially lipids

[@MedicosisPerfectionalis]

Thank you so much 😊 I will try my best!

Best As always Sir you are legend 😎🔥

[@MedicosisPerfectionalis]

[@SapphireZeev36]

20:32 if greater the calcium=less excitability, how do I better understand this with regards to verapamil (which among other uses) decreasing tachyarrhythmia

[@MedicosisPerfectionalis]

There's a difference between serum calcium concentration and blocking a calcium channel in a target organ.

[@SapphireZeev36]

@@MedicosisPerfectionalis correct. I assumed as much I was hoping someone could elucidate on that because it was still talking about the heart.

[@ayeshafaiza5572]

Thank you sir 🤓

Extremely underated channel sir 🤧 Kind suggestion you can do shorts video feature and get more students in to this. Beautiful class room 😍

What is the clinical application of chronaxie and rheobase? Is it important for an electromyogram?

[@ThatsWhy-]

I Like you when you cuss ' "oh just SHUT UP" '

[@MedicosisPerfectionalis]

Haha 😂

[@MohsenMohamed-h7r]

Hey medicosis some people say you are egyptian is that right?

[@samiiula]

It's E. Na channels are high at the level of nodes of Ranvier.

[@ThatsWhy-]

The answer : "C" to pump na+_ca++

[@ThatsWhy-]

What is the difference between electro-gradient AND osmosis gradient? What is the relation between the two?? Help me to grasp the meanings of the two, please

[@0584-h7k]

"yes ma'am" 🤣

[@MedicosisPerfectionalis]

Haha 😂

[@zakirzak1494]

Answer is C ... helix point for higher Na channels

[@MedicosisPerfectionalis]

Are you sure?

[@zakirzak1494]

@@MedicosisPerfectionalis guessed... unsure

[@yebelaylijzd1250]

Wow

[@muhammadaliaslam4023]

Sir! As u said that In case of Non excitable cells eg RBCs that have less negative RMP(Less K+ Efflux) but When We say in case of Hyperkalemia there is less K+ Efflux or Less negative RMP they become more Excitable, Isn't it Contrary? BTW thanks for Glorious Video. Kindly Sir explain it

[@anasaitkhouya7898]

Exactly, i think for hyperkalemia there is more K+ in the ECF thus more negative Membrane potential so less excitability. Makes also sense for hypokalemia.

[@charisuwaa6204]

Old topic. Now you decided do it

[@MedicosisPerfectionalis]

Yup

Imagine studying overseas with a lecturer who cant really deliver their understanding to foreign students 🥲 thank u ! Finally can understand
