Serotonin (5HT) is a neurotransmitter associated with mood, sleep, and psychosis. There
are several serotonin receptors all over the human body. A unique aspect of the second
generation antipsychotics is their ability to block 5HT2a receptors. What is the effect of
this inhibition?
Selected A.
Answer: Stabilizes dopamine concentrations
in the CNS
Answers: A.
Stabilizes dopamine concentrations
in the CNS
B.
Induces anxiety
C.
Causes hallucinations
D.
Reduces platelet function
Response B represents antagonism of 5HT1a, C represents a 5HT2a agonist,
Feedback: and D represents what happens when you inhibit SERT.

Receptors trigger one of two effector pathways resulting in changes in neuronal activity.
These changes will, ultimately, effect gene expression. Which effector pathway is
characterized by ion flux through transmitter-activated channels resulting in an altered
membrane potential and neuronal activity?
Selected D.
Answer: NMDA glutamate receptor
pathways
Answers: A.
Slow effector pathways
B.
Modulated effector pathways
C.
Rapid effector pathways
D.
NMDA glutamate receptor
