When an action potential reaches the end of an axon, an electrical impulse is then converted into a chemical signal.
To transmit messages from one neuron to the next, an action potential is created. It is produced when the sodium ions pass through the axonal membrane and cause a potential difference. A positive charge develops in the axoplasm whereas a negative charge accumulates outside the membrane.
"The places of contact between neurons known as synapses. Presynaptic neuron, synaptic cleft, and postsynaptic neuron are the three components, which most frequently occur between axons and dendrites." Signal transmission from one neuron to another occurs through the release of chemical neurotransmitters.
