Cannon Situation

He is interesting to indicate that the fear to the physical damage brings about the same reaction that the fear to a psychic pain. The certain thing, remembers to us Elena Go’mez, who implied physiological changes in a provoking situation of fear are pronounced. Recurdese that the implied physiological systems, at interactive level, par excellence, are: the independent nervous system and the endocrine system. The subsequent answer, before atemorizante stimulus, triggered by these systems, was investigated by Cannon and Selye that studied the immediate reaction of the organism (Cannon) and the adaptation of the same before a continued situation of stress (Selye). (Reactions of alarm and period of resistance). The mobilization of the corporal resources, adapted for attack-flight answer, against the danger, is shown through the activation of the likeable nervous system and the adrenal marrow that is going to secrete hormones like the epinefrina and norepinefrina *, if the situation stays, goes of the alarm reaction, to the period of resistance and the control happens of the marrow to the adrenal crust and to the adenohipfisis, implied hormones are denominated antiflogisticas (they reduce the inflammatory processes) and glucocorticoids are related to the metabolism of sugars in the organism (: hidrocortisona, corticosterona and cortisone), therefore, are related to the contribution of energy to the same in the phase of resistance of which we spoke. Prolonged stress, produces a diminution in the activity of the thyroid (diminution of tiroidea stimulating hormone) and a smaller secretion of the hormone of the growth.

Also there is a clear repercussion of the stress continued in the alteration of the sexual and reproductive behavior, takes place, therefore before a situation it continues of emergencia in the organism, a smaller activity of the growth, reproduction and defenses in front of infectious processes, as much it is the cause of stress: psychological, by surgical traumatism or environmental cause (Gray, 1971). Concretely Go’mez thinks, who the fear is a reaction of protection on the part of the organism that also depends on the filogentico development and on the concrete situation in that one takes place. Present Tngase that are several ways, in which it is reacted to the fear like: The attack; the flight; the paralyzation or some intersocial conducts of submission against dominance * suggested References: . – Gray, Jeffrey A.
