such as gamma-aminobutyric acid, glutamate and glycine are all members of the family of chemical substances which are secreted by neurons to facilitate the neurotransmission of an action potential from one neuron to the next adjacent neuron or cell. Nerve signals are classed as jumping across neurons when in reality the transmission of an action potential is just the start of a new impulse.
NEUROTRANSMITTER: "A substance which diffuses across the synaptic cleft from one synapse to another is called a neurotransmitter, these facilitate neurotransmission."
