It's like everywhere I get stuck in physiology, this channel has a solution for it. Upto the point. No beating around the bush. Just what a student need to study the syllabus better. You, ma'am, is a hero.No kidding. So much respect and love for you.

Comment below: Why SA node has highest rate of impulse generation among autorhythmic cells ? Answer lies in the pacemaker action potential....
@iazahussainzz
4 жыл бұрын
cells in the SA node have a higher conductance for sodium ions, so they continually fire leading to more frequent action potentials
@PhysiologyOpen
4 жыл бұрын
Yes, the rate is higher than other pacemaker cells like AV node (they also have pacemaker potential), because the prepotential slope is steeper in SA node because of higher conductance

Movement of very few ions in the range of 1/300000..causes changes in membrane potential. Moreover, sodium potassium ATPase always works and with change in any ionic concentration, it starts working even faster

At the end of phase 3 , the potassium has moved outside the cell, also sodium and calcium has moved inside the cell. So, how does the next cycle of action potential generate? Can anyone explain please.

NaCaATPase moves Ca out of the cells. Na K ATPase throws Na out and brings K in

Please answer me , the funny channels are permeable to sodium and potassium ions in the the same time ,,,,so the funny current is a complex of sodium and potassium ions current ,sodium inward ,but what about potassium,inward or outward ,please answer,I really need your help.

That’s also depolarisation. Depolarisation is any change in potential towards positive..when it crosses threshold it is action potential (which is always depolarisation)

Hello mam. There is a sentence given in G K Pal Textbook of Medical Physiology on pg. 554 which states as follows " Actually, it is the resting membrane potential that automatically depolarizes to form the pacemaker potential. Thus in pacemaking tissues there is no resting membrane potential, rather the pacemaker potential is the restless membrane potential. But isn't the resting membrane potential of pacemaker tissue also know as the pacemaker potential? Can you please explain mam?
