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.
Pediatricians graduate from medical school and then take special courses solely in pediatrics for three or more years. This is called residency. Under supervised conditions, the pediatrician-in-training acquires the knowledge and skills necessary to treat a broad range of conditions, from the mildest childhood illnesses to the most serious diseases.
