Nerve Impulse
Section 35-2
Action Potential
As the action potential passes, potassium gates
open, allowing K ions to flow out.
At rest.
Action Potential
Action Potential
The action potential continues to move along the
axon in the direction of the nerve impulse.
At the leading edge of the impulse, the sodium
gates open. The membrane becomes more permeable
to Na ions and an action potential occurs.

The Synapse When an impulse reaches the end of
one neuron, neurotransmitters are released into
the synaptic cleft
