thanks sir ! I think i understand accommodation now but can you explain what is its correlation with hyperkalemia because it is not very clear on brs physiology.
hyperkalemia(high K+ in ECF) causes more ICF K+ to stay inside the cell, hence making the inner part of the nerve membrane less -ve. So the size of RMP decreases.
This is my understanding: From RMP till the threshold value ligand gated sodium channels are involved. Any potentials in this range are local graded potentials; graded based on the initial intensity of the stimulus. At the threshold voltage gated channels open (in a positive feedback regulatory mechanism) causing the surge of sodium influx you speak of.

Best explanation ever full conceptual clarity thank you Sir ❤.
Your explanations are the best!! please make more such videos... especially on complex topics of neurophysiology
Very well explained sir. Thank you
Thank you sir
It was very useful
Well explained
Thank you sir ♥️
Thank you from Germany 😊
😍😍😍 yeyyyyyy... Thank you sir

soo clear , i like it sir

Is it possible to read more about the "slow" potassium channels in relation to accommodation? If yes, where do I find it? :D
Berne & Levy,
Boron & Boulpaep.
These two are the best titles for the molecular physiology.
