The fight-or-flight response, also known as the acute stress response, refers to a psychological reaction that occurs in the presence of something that is terrifying, either mentally or physically. The fight-or-flight response was first described in the 1920s by American physiologist Walter Cannon.
Where Pediatricians Work Some pediatricians work in an office, either alone or with a group of other doctors, while some work in a hospital, health maintenance organization, clinic, or medical school. Still, others work as locum tenems doctors, traveling around a city or around the country, filling in for other doctors on a part-time basis.
A medical practitioner who specializes in this area is known as a pediatrician, or paediatrician. The word pediatrics and its cognates mean healer of children; they derive from two Greek words: ÏÎ±á¿Ï (pais child) and á¼°Î±ÏÏÏÏ (iatros doctor, healer). Pediatricians work both in hospitals, particularly those working in its specialized subfields such as neonatology, and as primary care physicians.
