Tree Number(s): D12.776.543.750.670.800.200.100; D12.776.543.750.695.800.200.100; D12.776.543.750.720.850.200.100
Unique ID: D044402
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D044402
Scope Note: A serotonin receptor subtype found widely distributed in peripheral tissues where it mediates the contractile responses of variety of tissues that contain SMOOTH MUSCLE. Selective 5-HT2A receptor antagonists include KETANSERIN. The 5-HT2A subtype is also located in BASAL GANGLIA and CEREBRAL CORTEX of the BRAIN where it mediates the effects of HALLUCINOGENS such as LSD.
