MeSH definition : 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.;
