Resting Membrane Potential


Neuron: Resting Potential To Action Potential To Refractory Potential

Resting Potential 

   The state during which no nerve impulse is being conducted along the neuron.





             Resting Membrane Potential is generated by differences in ionic make up 

               Differences in ionic make up of intracellular and extracellular fluid




Basis Of Resting Membrane Potential 

                 Differences in ionic make up of intracellular and extracellular fluid




When a cell is at rest

The pumping of Na-K ATPase exactly equals the diffusion of Na and K

3 Na out and 2 K in 





RMP Calculated: Nernst and Goldman Equation



RMP in Different Cells




RMP of a Neuron is  - 70  MV
