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.
What is a nerve impulse? A nerve impulse, or an action potential, is a series of electrical responses that occur in the cell. (Fig. 2) With the appropriate stimulation, the voltage in the dendrite of the neuron will become somewhat less negative.This change in the membrane potential, called depolarization, will cause the voltage-gated sodium channels to open. Sodium ions will rush in, resulting in a rapid change in the charge.At the peak of the action potential, that area of the neuron is about 40 mV positive. As the voltage becomes positive, the sodium channels close, or inactivate, and the voltage-gated potassium channels open.These potassium channels let potassium ions rush out of the cell, causing the voltage to become negative again.) With the appropriate stimulation, the voltage in the dendrite of the neuron will become somewhat less negative. This change in the membrane potential, called depolarization, will cause the voltage-gated sodium channels to open. Sodium ions will rush in, resulting in a rapid change in the charge.
