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)
The chemical used to send messages across synapses is acetylcholine or ACh.
The synapse releases a chemical that can diffuse across the gap between two neurones. The synapse has a large surface area, which means diffusion of the chemical can occur at a higher rate.
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
A synapse, chemical signals called neurotransmitters cross these gaps, carrying on the signal.
Chemical diffusion
exocytosis

Chemical
The answer is NEUROTRANSMITTER.
They act as an active "bridge".
Chemical synapses are specialized junctions through which neurons signal to each other and to non-neuronal cells such as those in muscles or glands. At a chemical synapse, one neuron releases a neurotransmitter into a small space (the synapse) that is adjacent to another neuron.
