The correct spelling of the word is actually "adrenaline," which is pronounced /əˈdriːnəlɪn/ according to the IPA phonetic transcription. This hormone is produced by the adrenal glands and is also known as epinephrine. It plays a crucial role in the body's "fight or flight" response, increasing heart rate, dilating pupils, and releasing glucose into the bloodstream. The misspelling "adnephrin" may have arisen due to a misunderstanding of the word's origins and pronunciation. It is important to use correct spelling and pronunciation when discussing medical terms to avoid confusion and ensure clear communication.
Trade name of a preparation made from the adrenal gland, possessing vasoconstrictor and hemostatic properties.
