Adrenaline is a hormone and medication which is involved in regulating visceral functions (e.g., respiration).
Epinephrine aka adrenaline is normally produced both by the adrenal glands and by a small number of neurons in the medulla oblongata. It plays an important role in the fight or flight response by increasing blood flow to muscles, output of the heart by acting on the SA node, pupil dilation response and blood sugar level.
As a medication, it is used to treat a number of conditions including allergic reaction anaphylaxis, cardiac arrest, and superficial bleeding.
It may also be used for asthma when other treatments are not effective.
