Complete the following statements.

The difference in charge across the membrane is called the
.
It is measured in
.
At resting potential, the charge of the outside of the neuron is
and
the inside is
.
Once a stimulus changes the membrane potential, the neuron conducts an impulse called a(n)
.
This causes the charge outside the cell to temporarily become
and
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.
