Adrenaline, also known as epinephrine, is a hormone and medication[7][8] which is involved in regulating visceral functions (e.g., respiration).[7][9] It appears as a white microcrystalline granule.[10] Adrenaline is normally produced by the adrenal glands and by a small number of neurons in the medulla oblongata.[11] It plays an essential role in the fight-or-flight response by increasing blood flow to muscles, heart output by acting on the SA node,[12] pupil dilation response, and blood sugar level.[13][14] It does this by binding to alpha and beta receptors.[14] It is found in many animals, including humans, and some single-celled organisms.[15][16] It has also been isolated from the plant Scoparia dulcis found in Northern Vietnam.[17]

Epinephrine occurs in only a small number of central neurons, all located in the medulla. Epinephrine is involved in visceral functions, such as the control of respiration. It is also produced by the adrenal medulla.
