[ WP ] Use proper medical/technical terms to describe an emotion in the human body .

It is often said that emotion is one of those lower order functions; a primitive function of the hindbrain. Alas, with the integration of the hippocampus and other, lesser known, memory centres, the brain has concocted a lethal understanding of emotion and its manipulation. 
 
 Seratonin, dopamine, and coritsol do most of the work. But their slight changes in the biochemistry of the brain spur physiological and anatomical changes we read and experience. The softness of a loved one's face, the vicious tooth bearing of an angry customer, all processed by those fluctuating levels of chemicals. 
 
 And we read them, more or less. The grace a person has in deciphering these emotions. Babies, with no form of learned experience, can experience fear and adoration depending on how your face is positioned. The fifty-five facial muscles provide the symphony of emotion that we read; appreciating and shying away from in the context of a situation. 
 
 Actors can manipulate this well. The passion, the hurt, the shame, and the love are all bandied around on stage, moving the audience to tears or laugh with wanton abandon. Their manipulation of their true emotive state to that of an assumed character moves our emotions through their actions and words. It's all controlled by those three chemicals: seratonin, dopamine, and cortisol.
