Emotion

In psychology and common use, emotion is an aspect of a human being's mental state, normally based in or tied to the person's internal (physical) and external (social) sensory feeling. Love, hate, courage, fear, joy, sadness, pleasure and disgust can all be described in philosophical (encompassing theological and non-physiological psychological views) and physiological terms. It is unclear whether animals or all human beings experience emotion.

Physical responses to emotion

The body frequently responds to Shame by warmth in the upper chest and face, Fear by a heightened heartbeat, increased "flinch" response, and increased muscle tension. Sadness by a feeling of tightness in the throat and eyes, and relaxation in the arms and legs. Desire can be accompanied by a dry throat and heavy breathing.
