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)

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

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 2 года назад

Wow 🤩 Thank you 😊

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

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

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 11 месяцев назад

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

@SapphireZeev36 11 месяцев назад

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

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

@muhammadaliaslam4023 2 года назад

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 Год назад

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.
