The answer is NEUROTRANSMITTER.
There is not just one chemical secreted into synapses (the gaps between neurons); instead, there are many chemicals secreted from the terminal buttons of neurons into the synapses. They are called "neurotransmitters."
A synapse, chemical signals called neurotransmitters cross these gaps, carrying on the signal.
By a chemical released by an axon.
no, synapse. node of ranvier is between axon and dendrites
A synapse is the junction or a point of close contact between two neurons.
The space junction between two neurons is called a synapse. It is a small gap where the electrical signal in the form of an action potential is converted into a chemical signal in the form of neurotransmitters to allow communication between neurons.
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.)
A synapse.

Synapses
The junction between two neurons is called a synapse. At the synapse, the electrical signal in the first neuron (presynaptic neuron) is converted into a chemical signal in the form of neurotransmitters, which then travel across the synapse and are received by the second neuron (postsynaptic neuron) to continue the signal transmission.
