Question

Nitric oxide

Quizplus · Accepted Answer

Nitric oxide (NO) plays a role in the regulation of cerebral blood flow. In the brain, NO is produced by endothelial cells, neurons, and glial cells. NO dilates blood vessels in metabolically active brain regions, which increases blood flow to the brain areas that need it most. This is thought to be an important mechanism for regulating brain energy metabolism in response to changes in neuronal activity. NO does not block penile erections or serve as a measure of brain catabolism, and while it is produced from the amino acid arginine, this is not the best choice as it is less specific to the role of NO in the brain.
