Final answer:
Neurons send messages to one another by releasing neurotransmitters, which transmit signals through synapses into other neurons.
Step-by-step explanation:
Neurons send messages to one another by releasing chemicals called neurotransmitters. These neurotransmitters are released from the axon terminals of one neuron and transmit signals through synapses into other neurons via the second neuron's axons. This is how information is communicated between different parts of the central nervous system.
