This is known as a cell's resting potential, and it can range from -90 to -30 millivolts depending on the type of cell. For neurons, however, the resting potential is usually around -70 millivolts. When an impulse, which is also known as an action potential, passes through a neuron...

if sensitivity of mammalian cells to magnetic fields is mediated by subthreshold changes in membrane potential, as in sensory transduction of sound, light, and other stimuli, then the ion channels responsible for the putative changes are probably present only in specialized sensory neurons or neuroepi...
2 Our neurons are more permeable to potassium than sodium, which is why we have a resting membrane potential of -70mV. Now we’re ready to learn about ACTION POTENTIALS Here’s the membrane of an axon at rest: Suddenly, there’s an influx of Na+. This influx raises the charge of ...

(Ca) ions are also important in maintaining the resting membrane potential in muscle cells. The Ca2+ions are stored in an organelle called the sarcoplasmic reticulum, which contains protein pumps to maintain high concentrations of Ca2+inside the compartment. When amuscle cellis told to contract, ...
