What happens when we get emotionally aroused?

Well, there is a small tissue in the Limbic System (emotional command center) of our brain called the "Amygdala" which controls our reaction to fear and anger as well as other negative emotions. Our bodily reactions to fear and anger are almost identical.

When fear or anger emotion is aroused, a message from the brain goes through the sympathetic pathway to the adrenal gland, adrenalin (hormone) is secreted into the blood, and the blood carries it to the whole body.

Organs in the body begin to react in unusual ways, preparing the body for action. The heart beats faster, breathing becomes heavier, muscles become tense, pupils dilate, hair stand on end, blood rushes to the capillaries in the face, muscles in the face contract to distort facial expression, intestinal movements (digestion, etc) cease. This special way the body reacts is commonly termed the "fight or flight," reaction, which is controlled by the Amygdala.
