serotonin
5-hydroxytryptamine (5-HT). A NEUROTRANSMITTER and HORMONE found in many tissues, especially the brain, the intestinal lining and the blood platelets. Serotonin is concerned in controlling mood and levels of consciousness. Its action is disturbed by some hallucinogenic drugs and imitated by others. It constricts small blood vessels, cuts down acid secretion by the stomach and contracts the muscles in the wall of the intestine.Collins Dictionary of Medicine © Robert M. Youngson 2004, 2005
serotonin
a pharmacologically active compound, derived from tryptophan, which acts as a vasodilator, increases capillary permeability, and causes contraction of smooth muscle.Collins Dictionary of Biology, 3rd ed. © W. G. Hale, V. A. Saunders, J. P. Margham 2005
Serotonin
A chemical produced by the brain that functions as a neurotransmitter. Low serotonin levels are associated with mood disorders, particularly depression. Medications known as selective serotonin reuptake inhibitors (SSRIs) are used to treat BDD and other disorders characterized by depressed mood.
