Objective: SWBAT describe how sodium is involved in a nerve signal.
Agenda:
Action Potential Webquest
Effect of Sodium Deficiency
HW: How would a sodium deficiency effect a nervous signal? Describe how it would affect the ability of an action potential to move through along the cell membrane.
Using these websites, consider the following questions:
How does the neuron cell membrane cause changes in the concentration of Na and K ions inside and outside the cell?
Describe what happens to the ion concentrations on each side of the cell membrane during each of these phases: resting potential, depolarization, repolarization, return to resting potential.
How does the action potential move down the length of the neuron?
