Class A Fires consist of ordinary combustibles such as wood, paper, trash or anything else that leaves an ash. Water works best to extinguish a Class A fire. Class B Fires are fueled by flammable or combustible liquids, which include oil, gasoline, and other similar materials.
The amygdala is involved in our experience of emotion and in tying emotional meaning to our memories. The hypothalamus regulates a number of homeostatic processes, including the regulation of body temperature, appetite, and blood pressure.
For its part, the amygdala enables one of the forms of implicit memory: emotional memories associated with fear. Various aspects of an especially emotional situation such as a car accident will therefore be processed both by the hippocampus and by the amygdala, working in parallel.
