How Does a Nerve Impulse Travel Down an Axon

A nerve impulse travels along the neuron in the form of electrical and chemical signals. The axon tip ends at a synapse. … For a nerve impulse to be carried along at a synapse, it must cross the gap between the axon and the next structure. The axon tips release chemicals that carry the impulse across the gap.

What are the steps of nerve impulse transmission?

The action potential travels rapidly down the neuron’s axon as an electric current and occurs in three stages: Depolarization, Repolarization and Recovery. A nerve impulse is transmitted to another cell at either an electrical or a chemical synapse .

What travels down the axon of a neuron?

The electrical signal that travels down an axon is called a nerve impulse.
