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.
Neural impulse transmission is, therefore, electrochemical in nature. In the resting state -- the period during which a neuron is not conducting -- the fluids outside the cell membrane carry a relatively high positive charge.
