Serotonin or 5-hydroxytryptamine (5-HT) is a monoamine neurotransmitter derived from tryptophan, primarily found in the gastrointestinal (GI) tract, platelets, and in the central nervous system (CNS). In Gut, serotonin regulates intestinal movements, in CNS, it regulates mood, appetite, sleep, memory and learning, etc.

     Hormone Serotonin or 5-hydroxytryptamine (5-HT) and arterial vessels

The vasodilator effects of serotonin can be caused by (a) inhibiting vascular smooth muscle directly, (b) releasing other inhibitory substances, such as vasoactive intestinal polypeptide, (c) inhibiting adrenergic neurotransmission, and (d) triggering of endothelium-dependent relaxation, according to the study by J Cardiovasc Pharmacol. 1984;6 Suppl 2:S421-8(15).
