The chemical used to send messages across synapses is acetylcholine or ACh.
response disorder with ptyalin secretion
A neuron is a nerve cell. A synapse is a gap between the sending and receiving neurons, where there are neurotransmitters responsible for transporting chemicals to the receiving neuron. (A neurotransmitter is a chemical messenger.)
Chemical Synapse
Acetylcholine is the chemical that crosses the synapse causing a muscle to contract. It is released due to an electrical impulse sent from your brain down your nervous system.
A synapse, chemical signals called neurotransmitters cross these gaps, carrying on the signal.

Chemical diffusion

YES IN SORTS...A SYNAPSE IS THE RELEASE STRESS IN NERVE ENDINGS....USUALLY HAPPENS RIGHT BEFORE YOU FALL ASLEEP....SORTA LIKE THEY R WINDING DOWN FOR THE NIGHT...( IM SURE YOU FELT THE JUMPS OR CONTRACTION WHILE YOU ARE FALLING ASLEEP)
Chemical
The impulse must go from one neuron to the next. To do this, it must change from an electrical to a chemical signal, and back to an electrical signal when it reaches the next neuron. Electrical signals are impossibly fast, but neurotransmitters cannot cross a synapse that fast. So, the impulse is at its slowest point when it crosses the synapse.
They act as an active "bridge".
The answer is NEUROTRANSMITTER.
