Abstract: Catecholamines are recognized to play an important part in the fight-or-flight response to impending stress. Catecholamine and other phase-reactant levels are raised in the first 24 h following acute stress, but the bigger picture of their action on the organism is unavailable. In ...
Fight or Flight: The popularly termed fight or flight response involves an animal (including humans) responding rather suddenly, as if to engage in a fight or to exit the area where a fight may occur, when there is a conflic...
Kcnj5, encoding the inward-rectifier K+channel Kir3.4, a type of G protein-gated ion channel contributing the acetylcholine-activated current, is preferentially expressed in the atria, accounting for the specificity of vagal control of heart rate and conduction velocity...
Although its primary function is to stimulate the ‘fight, flight or freeze’ response, the SNS is constantly active at a basal level to maintain homeostasis in haemodynamics by inducing a vasoconstrictor effect in most vessels. Conduit arteries Also known as conducting arteries or elastic arteries...
Such sounds and sights were usually benign, but in case they were not, the immediate triggering of the fight-or-flight response would have saved an early human from an early grave. Albeit possessing the same properties as other mechanisms whose function is the detection of animate beings, ...

This happens because there is a direct neurological link between trauma and health, including impairment of different parts of the brain. The brain’s fight or flight system is activated in response to threats, and if threats become more frequent then the system is activated far more frequently,...
In October 2019, French President Emmanuel Macron hadwarned against “stigmatising” Muslims or linking the Islamic religion with the fight against terrorism. “Communalism is not terrorism.” There are many factors that can influence how Muslim and Western societies interact and respect each other....
and innate behavior benefits from information about the learned contexts in which benefits or threats are realized. For example, a rigid, rapid fight-or-flight response is crucial when danger looms, but may lead to opportunity costs or overt harm when deployed in an inappropriate context [16]....
One major issue with this technique is that the distress caused by tail-handling29 is detrimental not only to the animal used, but could interfere with the secretome being investigated, as fight-or-flight responses are also mediated through hormonal secretion by bone30. In addition, the ...
