describe the terms absolute refractory period, relative refractory period, sodium equilibrium potential, and the significance of Nernst equation.

1. Define the term: Absolute refractory period.

2. Why does the absolute refractory period occur? What is happening in the cell?

3. Define the term: Relative refractory period

4. Can the cell generate another action potential during the relative refractory period? If so, what is needed to evoke this response?

5. What is the nature of the response that is invoked? In other words, is the response evoked stronger than normal, weaker than normal, the same as usual? Why?

6. What is the importance of establishing sodium equilibrium potential?

7. What is the significance of the Nernst Equation with regard to the movement of Na+ ions? Is the importance focused on the ability to generate an impulse at the end? Or, is it focused on creating an action potential instead? Why?

8. What is the implication of the Nernst Equation with regard to the movement of K+ ions? Is the importance the same as the answer you just gave in Q. 13.g. above? Why or Why Not? give details?
