Concept of trauma

Trauma - an anatomical or physiological disorder of the body, caused by the external factor. Traumas are divided into mechanical, physical, chemical, biological and mental.

Mechanical injuries are open (wounds), which occur with violation of cutaneous or mucous membranes, and closed - without damaging them.

Physical injuries occur in case of high or low temperatures (burns, heat stroke, frostbite, etc.), electric current (electric trauma, lightning) and radiation energy (sunburn, radiation sickness).

Chemical injuries are caused by acids, alkalis, poisons, poisonous substances.

Biological traumas are caused by the action of bacterial toxins.

Psychic traumas are the result of reflex stimulation of the central nervous system by strong or unexpected stimuli (for example, fright).
