Introduction (Page 1 of 11)
Goals (Page 2 of 11)
The Concentration of Ions Differs Inside and Outside the Cell (Page 3 of 11)
Permeability Depends on the Number of Ion Channels (Page 4 of 11)
Permeability Can Change Rapidly When Gated Ion Channels Are Opened (Page 5 of 11)
K+ Diffuses Down Its Concentration Gradient (Page 6 of 11)
Outward Diffusion of K+ Creates an Electrical Potential (Page 7 of 11)
K+ Leaks out of the Neuron and Na+ Leaks in (Page 8 of 11)
The Neuron Must Compensate for K+ and Na+ Leaks (Page 9 of 11)
The Na+-K+ Pump Maintains the Resting Membrane Potential (Page 10 of 11)
