Must Learm: - Channels - Types - Voltage Gated - Depolarization / Repolarization / Hyperpolarization - Na+, K+, Cl- - Channels In Neurons - Most: Voltage-gates, Na+ inward, K+ outward. - Voltage-gated Ca2+ opened in response to depolarization, inward Ca to helpdepolarize - Some neurons have voltage-gated Cl- to help repolarization - Some voltage-avtivated K+ channels differ in
