PPT-Modeling the Action Potential in a Squid Giant Axon

And how this relates to the beating of your heart Outline The story of an action potential Digression Heartbeats and action potentials Ion Channels Three stages Polarization and resting state. Action potentials serve a very different function in neu ronal cell bodies where they encode information in their frequency and pattern than in axons where they serve primarily to rapidly propagate signals over distance The membrane of the squid axo By: Forrest Palmore.
