Chemical Synapse
The answer is NEUROTRANSMITTER.
The chemical released by the axon that travels across a synapse and binds to dendrites or cells is called a neurotransmitter. Neurotransmitters play a crucial role in transmitting signals between neurons and regulating various physiological processes in the body.
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.

At a chemical synapse, neurotransmitters are released from the presynaptic neuron and bind to specific receptors on the postsynaptic neuron's membrane. This binding triggers changes in the postsynaptic cell, such as the opening of ion channels, leading to either excitatory or inhibitory effects depending on the type of neurotransmitter involved. This process facilitates communication between neurons, allowing for the transmission of signals throughout the nervous system. Ultimately, neurotransmitters play a crucial role in regulating various physiological processes and behaviors.
A synapse, chemical signals called neurotransmitters cross these gaps, carrying on the signal.
Membrane receptors at a synapse are ligand-gated ion channels that open and allow sodium ions to flow into the neuron upon binding of the neurotransmitter ligand to generate an action potential in the neuron.
Neurotransmitters that cause a chemical change and hence generat impulse in the dendrites of adjacent neurons. most common neurotransmitter is acetylcholine
no, synapse. node of ranvier is between axon and dendrites
The action of the excitatory neurotransmitter will increase, since its concentration in the synapse will rise.
