An extremely high level of social inhibition is known as Social Anxiety Disorder, though is usually falselyperceived to be the result of a lack of confidence or self esteem.
Function of Electrochemical Impulses: In neurons, cell-to-cell communication is the major role of action potential. In other types of cells, activation of intracellular processes is their major function.
Many nerve cells are of the basic type illustrated above. Some kind of stimulus triggers an electric discharge of the cell which is analogous to the discharge of a capacitor. This produces an electrical pulse on the order of 50-70 millivolts called an action potential. The electrical impulse propagates down the fiber-like extension of the nerve cell (the axon). The speed of transmission depends upon the size of the fiber, but is on the order of tens of meters per second - not the speed of light transmission that occurs with electrical signals on wires.
