Neurotransmitter – chemical messenger

Neurotransmitters are chemical messengers that transmit signals across synapses, from one neurone to another.

A neurotransmitter is a chemical messenger carrying signals across the synapse gap
The new row of transmitters (neurotransmitters) all had chemical messages on them.

A neurotransmitter is a chemical substance which is released at the end of an axon, or nerve fibre, by the arrival of an electrical impulse. By diffusing across the synaptic cleft – the tiny gap between the end of an axon and a dendrite of the next neurone in the chain – and binding with receptor molecules on the second neurone, the chemical transfers the impulse to another neurone, or to a muscle or a gland.
