Terminal buttons of a neuron release neurotransmitters. These neurotransmitters are stored in synaptic vesicles within the terminal buttons. Axons transmit electrical impulses and dendrites receive signals. Transport proteins are involved in other processes like moving substances across membranes, not storing neurotransmitters.
