Neurotransmitters, which are chemicals that transmit signals across a synapse between nerve cells, are released from the nerve endings (axon terminals) of the presynaptic neuron.
The synapse is the junction between two nerve cells. When an action potential reaches the axon terminal, it triggers the release of neurotransmitters stored in vesicles into the synaptic cleft, where they bind to receptors on the postsynaptic neuron.
The cell body contains the nucleus and organelles, the nucleus contains genetic material, and the axon is the long projection that conducts the action potential away from the cell body. The nerve endings are specialized structures at the end of the axon.
