Quizplus · Accepted Answer

The Answer is The autonomic nervous system (ANS) connects several of the body's organs to the CNS. It is a motor system with an important role in the regulation of breathing, the heart rate and the operation of various glands. One common application of ANS measurement is the use of lie detectors. Generally measuring ANS activity via the sweat glands in the hands, lie detectors measure the degree of arousal - the working assumption being that people are more likely to be aroused (nervous, tense, anxious, fearful, frightened) when lying.
