High concentrations of all neurotransmitters, except for NO, are stored in the:
A) presynaptic terminals.
B) postsynaptic terminals.
C) axon.
D) cell body.

Question

Quizplus · Accepted Answer

High concentrations of all neurotransmitters, except for NO, are stored in presynaptic terminals. This is where the neurotransmitters are synthesized, packaged into vesicles, and released into the synaptic cleft during neurotransmission. The postsynaptic terminals receive the neurotransmitters and initiate a response, but they do not store large quantities of neurotransmitters. The axon is responsible for carrying the neurotransmitter signals to the synapse, but it does not store neurotransmitters. Lastly, the cell body is responsible for producing the neurotransmitter precursors, but it does not store neurotransmitters.
