But what is adrenalin? What does it mean? In this article, we will explore the definition, origin, and meaning of adrenalin.
Definitions
Adrenalin, also known as epinephrine, is a hormone and neurotransmitter produced by the adrenal glands. It is released into the bloodstream in response to stress or danger, preparing the body for a fight or flight response. Adrenalin increases heart rate, blood pressure, and breathing rate, while also dilating the pupils and increasing blood sugar levels.
Origin
The word adrenalin comes from the Latin word “ad” meaning “near” and “renes” meaning “kidneys”. This is because the adrenal glands, which produce adrenalin, are located near the kidneys.
