Final answer:
Neurotransmitters are released from axon terminals and transmit signals through synapses to the dendrites of the next neuron.
Step-by-step explanation:
Chemicals released at the axon terminals transmit signals through synapses into other neurons via the second neuron's dendrites. When a nerve impulse reaches the end of an axon, the axon releases chemicals called neurotransmitters. These neurotransmitters travel across the synapse between the axon and the dendrite of the next neuron. The neurotransmitters then bind to the membrane of the dendrite, allowing the nerve impulse to travel through the receiving neuron.
