WebNeurones are long cells which carry electrical signals along their length. Where two neurones meet there is a tiny gap called a synapse. The signal passes chemically across … WebThe process of sending these signals takes place in two steps: along the cell (action potential) and between cells (neurotransmitters). How does information travel? …

WebThe sequence transmission of an electrical impulse through neurons begins at the dendrites. The axon is a tubelike structure that carries an electrical impulse from the cell body to the axon terminals where the electrical impulse will pass to another neuron. This means that the axon is the main conducting unit of the neuron.

WebThe impulses move away from the cell body along the axon to the synaptic terminal where the impulse is sent to the next neuron (the interneuron) with the help of a neurotransmitter (acetylcholine).
