The head of a Roman snail, four tentacles well visible. [RN] Observing a snail crawling around, the view is immediately attracted by its head, orienting itself in its surroundings using the tentacles. The snail feels its environment, touches an obstacle and withdraws the tentacle.
One of these hormones is epinephrine, which can be defined as a hormone secreted by the adrenal medulla in response to short-term stress. Epinephrine is also called adrenaline, and you may have heard of this term before.
Norepinephrine is also made in the adrenal medulla where it synthesized from dopamine and is released into the blood as a hormone. Epinephrine is made from norepinephrine inside the adrenal medulla (the inner part of the adrenal gland, a small gland associated with the kidneys). Our adrenal medulla helps us to cope with physical and emotional stress. The synthesis of epinephrine increases during times of stress.
