Panic is a sudden sensation of fear, which is so strong as to dominate or prevent reason and logical thinking, replacing it with overwhelming feelings of anxiety and frantic agitation consistent with an animalistic fight-or-flight reaction. Panic may occur singularly in individuals or manifest suddenly in large groups as mass panic (closely related to herd behavior).
The word "panic" derives from antiquity and is a tribute to the ancient god Pan. One of the many gods in the mythology of ancient Greece, Pan was the god of shepherds and of woods and pastures. The Greeks believed that he often wandered peacefully through the woods, playing a pipe, but when accidentally awakened from his noontime nap he could give a great shout that would cause flocks to stampede. From this aspect of Pan's nature Greek authors derived the word panikos, “sudden fear,” the ultimate source of the English word: "panic". The Greek term indicates the feeling of total fear that is also sudden and often attributed to the presence of a god.
The fight-or-flight response (among other names) is a physiological reaction that occurs in response to a perceived harmful event, attack, or threat to survival. Animals react to threats with a general discharge of the sympathetic nervous system, preparing the animal for fighting or fleeing. The adrenal medulla produces a hormonal cascade that results in the secretion of catecholamines, especially norepinephrine and epinephrine. The hormones estrogen, testosterone, and cortisol, as well as the neurotransmitters dopamine and serotonin, also affect how organisms react to stress. The hormone osteocalcin might also play a part.
General adaptation syndrome regulates stress responses among vertebrates and other organisms involves the fight-or-flight response as it first stage.
