Neurotransmitters. It's purely chemical.
Neurotransmitters
neurons and synapses
yes
Nerve impulses are initiated and transmitted according to nerve reactions and messages that get passed along or transmitted along nerve synapses and zones.
Synapses. Net flow of charged ions ("impulses") in neuronal cells trigger additional ion flow (ionotropic signaling) or neurotransmitter release (metabotropic signaling) to both neuronal and non-neuronal cell types ("the body") at junctions called synapses.
neurotransmitters
they stop the signals travelling down the nerves by blokcing the synapses

A synapse is a small gap at the end of a neuron that allows information to pass from one neuron to the next.
Neurotransmitters the are means by which neurons communicate with one another. There are more than 30 compounds known to be neurotransmitters, and dozens of others are thought to be so. You will only find them in the peripheral nervous system as the central nervous system uses mainly electrical signals.
Nerves use electrical impulses to transmit signals to the brain. The gaps between the nerve endings are called synapses.
The dendrites of one neuron send electrical impulses called synapses to the axons of other neurons to transport information.
