Discuss the generation and propagation of action potentials.
In which ion gradient is the potential energy for formation of an action potential stored? How is this energy used to generate an action potential? How is an action potential initiated? What is meant by all-or-nothing response?
Graphically illustrate how axonal membrane potential changes with passage of an action potential. At various times in an action potential, describe the following: membrane voltage, sensitivity of sodium channel to voltage, sodium channel conductance, sensitivity of potassium channels to voltage, and potassium channel conductance.
Explain how the activity of a voltage-gated sodium channel depends on its structure.
How are action potentials propagated in unmyelinated and myelinated axons?
