Impulses in Nerve and Muscle Cells, the membrane, setting up currents that flow through the membrane and along the cell. Similar impulses travel along muscle cells before they contract. This chapter reviews the basic properties of electric fields and currents that are needed to understand the propagation of the nerveor muscle-cell im

The Exterior Potential and the Electrocardiogram,red and has clinical relevance. Before a muscle cell contracts, a wave of depolarization sweeps along the cell. This wave is quite similar to the wave along the axon. Measurement of these exterior signals gives us the electrocardiogram, the electromyogram, and the electroencephalogram.

It also discusses mechanisms for the detection of weak electric and
