Nitric oxide - Definition

Definition


Nitric oxide (NO), also known as nitrogen monoxide, is a naturally-occurring gas in the body. It acts as a neurotransmitter, namely a molecule capable of carrying messages, liberated by a nerve and sparking a reaction in cells it connects with. It is the only gas known to act in this way. It notably serves to transmit neural flow between several neurons, to cause blood vessels to dilate, and to make a certain number of involuntary muscles, such as those of the gut, to release.
