Activity of the sympathetic nervous system increases the electrical resistance of the skin by increasing:

Question

Quizplus · Accepted Answer

The sympathetic nervous system activates sweat glands, which increases the electrical conductivity of the skin. This is the basis for the measurement of skin conductance in psychophysiological research. As sweat increases, the electrical resistance of the skin decreases, allowing more current to pass through the skin. Therefore, sweating reduces the electrical resistance of the skin, not increases it. Heart rate, adrenal secretions, and breathing rate are not directly related to electrical resistance of the skin.
