Answer to Question #293122 in Human Anatomy and Physiology for polly

Question

How does the concentration of potassium ions compare inside the neuron versus outside the neuron during rest? 

Answer 1

The resting membrane potential of a neuron is about -70 mV (mV=millivolt) - this means that the inside of the neuron is 70 mV less than the outside. At rest, there are relatively more sodium ions outside the neuron and more potassium ions inside that neuron.
