Guide Questions with answers
A serotonin molecule binds to a 5HT2A receptor causing electrical impulses to
be sent down a GABA neuron's axon terminal, eventually releasing GABA to
the GABA-A receptor of its postsynaptic neuron. Which type of
neurotransmission does this describe?
A. Classic synaptic neurotransmission
B. Retrograde neurotransmission
C. Volume neurotransmission
D. Signal transduction cascade - ....🔰VERIFIED ANSWERS.... ✔✔A. Classic
synaptic neurotransmission
