The Role of the Autonomous Nervous System
Any stimulus that arouses an emotion - such as hug, a fire-alarm or a slp on the face alters the activity of the autonomous nervous system, the section of the nervous system that controls the functioning of internal organs. The word autonomic means independent; biologists once believed that the autonomic nervous system operated independently of the brain and the spinal cord. Brain and spinal cord send messages to alter the activity of the autonomic nervous system, but we continue to use the term autonomic.
The autonomic nervous system consists of the sympathetic and parasympathetic nervous systems.Two chains of neuron clusters just to the left and right of the spinal cord make up the sympathetic nervous system, which arouses the body for vigorous action. Sympathetic nervous system response increase your heart rate, breathing rate, production of sweat, and flow of epinephrine, thereby preparing you for intense activity.
The parasympathetic nervous system consists of neurons whose axons extend from the medulla and the lower part of the spinal cord to neuron clusters near the internal organs. The parasympathetic nervous system decreases the heart rate, promotes digestion, and in general supports nonemergency functions. Both the sympathetic and parasympathetic systems send axons to the heart, the digestive system, and the other organs.
Both systems are constantly active. The alteration or shifting balance between them helps keep the body of homeostasis, but one system can temporarily dominate the other. For example, a frightening situation may increase your heart rate and sweating and also promote bowel and bladder control.. Both sympathetic and parasympathetic nervous systems were responsible for those responses.
To conclude central nervous system plays an important role for emotional balance.Emotional Intelligence in social situations people need specific skills to judge other peoples emotions and intentions and the probable emotional outcomes of their own possible behaviors. People who misjudge others emotions can easily cause themselves in troubles. Many human facial expressions have similar meanings in cultures throughtout the world. Most studies of happiness rely on questionnaires and self-ratings. Happiness level appears to be fairly stable aspect of personality despite changes in people lives. It correlates with marriage and friendships, health, goals other than wealth, religious faith, and several aspects of personality.
