Is noradrenaline a hormone

Yes, noradrenaline, also known as norepinephrine, is a hormone as well as a neurotransmitter. It is produced by the adrenal glands and released into the bloodstream, where it plays a crucial role in the body's "fight or flight" response by increasing heart rate and blood pressure. In the nervous system, it functions as a neurotransmitter to transmit signals between nerve cells. Thus, it has both hormonal and neurotransmitter functions depending on its location and role in the body.
