The electrical activity of neurons: neurons do two important things, generate activities that create nerve impulses, release chemicals that allow communication with other neurons, muscles, glands. Ion channel: passageway or channel in the membrane that can open to allow the pass through of ions: fluid outside neuron: positively charged na+ ions and negatively charged cl- ions. Resting potential: the high concentration of sodium outside the cell, and of negatively charged protein ions inside, If the electrical charge rises above 70, the neuron is depolarizing. Info is provided concerning the nature of the stimulus: the myelin sheath, myelin sheath: a fatty, whitish insulation layer derived from glial cells during development.
