DEFENCE REACTION Meaning and
Definition
-
The term "defence reaction" refers to a psychological phenomenon characterized by the automatic and immediate response of an organism when encountering a threatening or potentially harmful stimulus. It is an innate and instinctive reaction that aims to protect an individual from danger or harm.
In humans, defence reactions are part of the body's natural defense mechanisms, triggered by the activation of the autonomic nervous system. When faced with a threat, the sympathetic nervous system is activated, leading to a fight-or-flight response. This response prepares the body to either confront the threat or flee from it, enabling the individual to effectively deal with the situation.
Common defence reactions include increased heart rate, elevated blood pressure, sharpened senses, increased muscle tension, and accelerated breathing. These physiological changes enhance the individual's physical abilities, enabling them to respond swiftly and appropriately in the face of danger.
Furthermore, defence reactions are accompanied by psychological changes, such as heightened alertness, fear, anxiety, or panic. These emotional responses help in prioritizing survival and aid in decision-making under stressful circumstances.
It is important to note that defence reactions can vary in intensity and duration depending on the individual and the specific threat encountered. Additionally, while defence reactions are primarily associated with immediate physical dangers, they can also manifest in response to perceived psychological threats or stressful situations.

Etymology of DEFENCE REACTION
The word "defence" comes from the Old French word "defense" meaning "protection, resistance", which in turn comes from the Latin word "defensus", the past participle of "defendere" meaning "to ward off, protect". The Latin word is a combination of "de" meaning "away" and "fendere" meaning "to strike". Thus, the idea behind "defence" is to "strike away" or "ward off" something that may pose a threat or danger. The word "reaction" comes from the Latin word "reactio", which is derived from the verb "reactus", the past participle of "reagere", meaning "to act again, to repeat, to respond". The prefix "re-" in Latin means "again" or "back". Therefore, "reaction" refers to an action or response that occurs in response to a particular stimulus or situation.
