At resting potential, the charge of the outside of the neuron is
and the inside is
The sodium-potassium pump helps maintain the resting potential.
The pump will move three
ions out of the cell while it moves two
ions into the cell.
Once a stimulus changes the membrane potential, the neuron conducts an impulse called a(n)
and
This causes the charge outside the cell to temporarily become
the inside to temporarily become
When the action potential arrives at the axon terminal it reaches a junction called the
Because the nerve impulse cannot cross the synaptic cleft,
are released.
