Answer each of the following questions and submit this assignment through the "Nervous System Worksheet" link on Blackboard

1. Define depolarization and hyperpolarization and their relationship to threshold.

2. Describe the process of depolarization of a neuron to threshold potential.

3. When nerve cells are at rest, there is an unequal amount of positive and negative charges on either side of a nerve cell membrane. This charge difference creates an electrical potential. Describe how the resting membrane potential (resting potential) is generated.

4. Describe the role of sodium ions and sodium channels in generating an action potential.
