Nervous System 11/27/07

Objective: SWBAT explain how the cell membrane is involved in nerve communication

Agenda:

• Action Potential WebQuest:
  
• Site 1 - actionpotential.swf from mcb.harvard.edu
• Site 2 - neuron action potential from blackwellpublishing.com
• Site 3 - action potential spreading from www.harveyproject.org
• Using these websites, consider the following questions:
1. How does the neuron cell membrane cause changes in the concentration of Na and K ions inside and outside the cell?
2. 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.
   
3. How does the action potential move down the length of the neuron?
