Answer to Question 1

Answer: Glial cells: provide physical or structural support for individual neurons; provide energy to neurons; take away waste products; buffer the environment of a nerve cell; provide insulation in the form of myelin; digest dead or dying nerve cells; are involved in immune function.

Answer to Question 2

Answer: Movements of the membrane potential past threshold, open sodium channels, which moves the membrane potential from -60 to roughly +40 mV. The sodium channels then close, and the potential is restored to resting by an opening of the potassium channels.
