Chapter 24, Problem 3WIO
Summary Introduction
To determine:
The way in which the charges are distributed in the membrane of a resting neuron.
Introduction:
Neurons send messages by transmitting an action potential. A neural impulse is the spread of an action potential like a wave along an axon. The membrane potential is the difference in electric charge inside and outside of a neuron. Depending on whether or not a neuron receives a stimulus, the membrane potential can change.
