- Acell body of nerve cell
- Bnucleus of nerve cell
- Cnerve endings of nerve cell
- Daxon of nerve cell
Explanation
Neurotransmitter chemicals are stored in synaptic vesicles clustered at the axon terminals (nerve endings) and released into the synaptic cleft when the nerve impulse arrives. The cell body integrates incoming signals, the nucleus carries genetic material, and the axon conducts the impulse — none of them releases the chemicals.
