action potential - the change in electrical potential associated with the passage of an impulse along the membrane of a muscle cell or nerve cell. Eppendymal cells - produce cerebrospinal fluid satellite cells - surround neuron cell bodies in PNS Schwann cells - produce myelin in PNS stages of AP - 1. depolarization-->threshold reached, Na+ IN --peak: VG Na+ channels Inactivate arization--> K+ OUT 3. hyperpolarization- K+ closes slowly, extra leaves Astrocytes (CNS) - for blood br...
