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.
16. An action potential, which is the nerve impulse, occurs when a threshold is reached. Upon stimulation, the sodium gates open, Na+ flows into the axon, and the action potential swings up from -65mV to +40 mV. During depolarization the inside of the fiber becomes positive as Na+ enters.. The axon of a neuron conducts nerve impulses away from the cell body. Neurons that conduct messages from a sense organ to the central nervous system are called sensory, or afferent neurons. Those neurons that conduct an impulse from the CNS to a muscle or gland are called. motor, or efferent, neurons.
