Sequence of Chemical Synapses

If you didn't see the attached document here's what the chart says:

1. An action potential in an excitatory presynaptic nerve.
2. An _____ in the dendrites of the postsynaptic nerve.
3. This spreads passively to the ___________.
4. Depolarization of this region opens voltage-gated ______ channels.
5. Suf?cient membrane depolarization to _________ opens enough of these channels to produce an action potential.

6.  IN NON MYELINATED AXONS: The currents associated with the action potential spread to the ______ region of the axon.

7. IN MYELINATED AXONS: The currents associated with the action potential spread to the next ________.

8. The action potential travels down the axon to the ___________.
