Adrenomedullin
Adrenomedullin (pronounced: ad-reno-me-dull-in) is a peptide hormone that is involved in various physiological processes. It was first discovered in 1993 in human pheochromocytoma, a type of adrenal gland tumor.
Etymology
The term "Adrenomedullin" is derived from the words "adreno", referring to the adrenal glands where it was first discovered, and "medulla", the inner part of an organ in contrast to the cortex.
Function
Adrenomedullin is a potent vasodilator, meaning it helps to widen blood vessels, leading to increased blood flow. It also has other functions such as promoting cell growth, regulating hormone secretion, and acting as an antimicrobial agent.
