Final answer:
An impulse is transferred from one neuron to another through the release and binding of neurotransmitters, which are chemicals that convey signals across a synapse.
Step-by-step explanation:
An impulse moves from one neuron to another through the action of neurotransmitters. These are chemicals that a neuron releases when an action potential reaches the end of an axon. Neurotransmitters travel across the synapse (the space between the axon of one neuron and the dendrite of another) and bind to the membrane of the dendrite on the receiving neuron, which allows the nerve impulse to continue.
Action potentials are electrical signals that travel within a neuron from the dendrites to the axon terminals, but the transmission of a signal from one neuron to the next is a chemical process which involves neurotransmitters. These substances are released into the synaptic cleft where they bind to receptors on the postsynaptic neuron's membrane, potentially causing a new action potential to begin in the next cell.
