Which structure stores neurotransmitters at the end of the neuron?

• A. Axon terminal
• B. Dendrite
• C. Cell body
• D. Synapse

Answer: (A)

Neurotransmitters are stored in vesicles within the presynaptic ending of the neuron called the axon terminal. When an action potential arrives, these vesicles release their contents into the synaptic cleft to transmit the signal to the next neuron. The dendrite is part of the postsynaptic neuron and mainly contains receptor sites for these chemicals, not storage vesicles. The cell body houses metabolic machinery, not neurotransmitter vesicles. The synapse refers to the gap and the junction structure itself, not the storage site. So, the structure that stores neurotransmitters at the end of the neuron is the axon terminal.
