resting potential of a neuron
neuron. 11.1.3 Define resting potential and action potential.
Here's an animation of an action potential in a neuron.
The Neural Membrane and Resting Potential
neuron action potential. The picture above makes it more clear.
At the leading edge of an action potential, sodium gates open,
Excess ions are subsequently pumped in/out of the neuron.
The membranes of all nerve cells have a potential difference across them,
The cause of the action potential is an exchange of ions across the neuron
Four Factors interact to produce the Resting Potential: CH04F04.BMP

An action potential generated at the axon hillock results in the changes of
Overview for a typical neuron. Two plots of the membrane potential (measured
The action potential is what gives rise to synapses; and is the building
The resting potential is maintained by the action of ion pumps.
Resting potential
The resting membrane potential for a neuron is about -70mV. (see Figure 3)
This allows the membrane potential to come back to the normal resting
The action potential at one membrane site provides a stimulus to adjacent
The neuron starts at resting membrane potential which is around -70 mv
In the case of neurons the so-called transmembrane resting potential is
