Demystifying the Brain’s Response
What triggers anxiety and how does the body respond?
A Peek into the Brain.

1. Hippocampus: this is the memory center, vital to storing the raw information coming in from the senses.
2. Auditory center visual stimuli: are responsible for sight and sounds.
3. Olfactory and tactile stimuli: smells and touch sensations.
4. Thalamus: is the hub for sights and sound.
5. Cortex: It gives raw sights and sounds meaning, enabling the brain to become conscious of what it is seeing or hearing.
6. Amygdala: The emotional core of the brain, the amygdala has the primary role of triggering the fear responses.
7. Bed nucleus of the stria terminalis: sets off an immediate burst of fear.
8. Locus ceruleus: it receives signals from the amygdala and is responsible for inhibiting many of the classic anxiety responses - rapid heartbeat, increased blood pressure, and sweating. 

The following list will show some of the mental and physical causes for anxiety and its relatives.  They are divided into two categories, mental and physical.  As we proceed you will see that the causes for some can be a combination of both
