What are the chemicals that the neurons use to communicate
A
neurotransmitter
B
Carbon Dioxide
C
Hydrogen
D
Axon
Explanation: 

Detailed explanation-1: -Synaptic vesicles contain a neurotransmitter (NT) and release it when their membranes fuse with the outer cell membrane. Neurotransmitter molecules cross the synaptic cleft and bind to receptors known as ligand-gated ion channels (LGICs) and G-protein–coupled receptors (GPCRs) on the postsynaptic neuron.

Detailed explanation-2: -Examples of excitatory neurotransmitters include glutamate, epinephrine and norepinephrine. Inhibitory. Inhibitory neurotransmitters block or prevent the chemical message from being passed along any farther. Gamma-aminobutyric acid (GABA), glycine and serotonin are examples of inhibitory neurotransmitters.

Detailed explanation-3: -Synapses: Dendrites receive signals from other neurons at specialized junctions called synapses. There is a small gap between two synapsed neurons, where neurotransmitters are released from one neuron to pass the signal to the next neuron.
