Document Summary

Studying how a neuron is able to communicate from a dendrite going down. Electricity a flow of electrons from a body that contains a higher charge (more electrons) to a body that contains a lower charge (fewer electrons) Negative pole the source of electrons; higher charge. Positive pole location to which electrons flow; lower charge. Electrical potential an electrical charge measured in volts; the ability to do work through the use of stored potential electrical energy: potential stored energy. Volt a measure of a difference in electrical potential: we"re going to measure volts in millivolts (mv) Voltmeter a device that measures the difference in electrical potential between two bodies. The negative pole has lots of electrons; the positive pole has fewer. There is electrical potential because there is a difference in volts between each pole. Neurons can convey information as a wave induced by stimulation on the cell body traveling down the axon to its terminal.
