Document Summary

By the end of this section you should know about: Specialized cells for reception, conductions and transmission of electrochemical signals. Dendrites: receivers of information from other neurons: comes in the form of electricity from another neuron, neurons connected dendrite to axon and the information flows. Membrane potential: the difference in electrical charge between the inside and outside of the cell: the membrane of a neuron maintains an electrical gradient difference in electrical charge between inside and outside. In the absence of any outside disturbance, the membrane maintains an electrical polarization or charge. The outside of the neuron is slightly negative with respect to the inside mainly because of the negatively charged proteins inside the cell. The neuron separates positive from negative charges. Each neuron is bounded by a membrane separating the intracellular and extracellular fluids, both of which contain ions (atoms bearing an electrical charge)
