Answer :
The resting membrane potential is maintained by electrostatic pressure and diffusion acting on the cation potassium.
What is a resting membrane?
It refers to the potential of a cell while at rest. All the neural activities start with a change in the resting membrane potential which is temporary and localized. The action potential is an electrical signal involving nerve cells.
This effect of resting membrane is a graded potential and decreases over distance from the stimulus. When it is large enough, an action potential is triggered in the membrane of the axon.
In conclusion, the resting membrane potential is maintained by electrostatic pressure and diffusion acting on the cation potassium.
