Textbook Question
Chapter 11.5, Problem 30AYP
What happens to cause depolarization and hyper-polarization? How do alterations in the K+ concentration gradient: changes in membrane permeability to K+, Na+, or Cl- and changes in
extracellular Ca2+ concentration affect depolarization and hyper-polarization?
