When the impulse reaches the end of one neuron (the axon), the impulse reaches a synapse. A synapse is the space between neurons. This space is filled with neurotransmitters, chemicals which allow the impulse to travel through the synapse to the next neuron.

In what order does a nerve impulse travel?

Nerve impulses begin in a dendrite, move toward the cell body, and then move down the axon. A nerve impulse travels along the neuron in the form of electrical and chemical signals. The axon tip ends at a synapse. A synapse is the junction between each axon tip and the next structure.

How does a nerve impulse travel?

When a nerve impulse reaches the end of an axon, the axon releases chemicals called neurotransmitters. Neurotransmitters travel across the synapse between the axon and the dendrite of the next neuron. ... The binding allows the nerve impulse to travel through the receiving neuron.
