General meaning of EMOTIONS

From my knowledges  emotions is like our feeling that we shows to other about whta we saw , touch , hearing and eat. Literally. We feel them in our bodies as tingles, hot spots and muscular tension. There are cognitive aspects, but the physical sensation is what makes them really different.Emotion is something that we can touch but we can fell.Emotion also can control our body reaction.as example when your were crying because of the emotion sad ,what will drop from you eyes?tear right? So that is the prove that emotion will control our body.As we know theres a lot of emotion but we not recognized what is emotions and what is not emotions.
