B) excitatory neurotransmitters are the function.
Neurotransmitters such as glutamate, adrenaline, and norepinephrine are some examples of the excitatory neurotransmitters. Inhibitory Neurotransmitters that act as inhibitors have the role to stop the chemical message from being transmitted further. Inhibitory neurotransmitters include glycine, serotonin, and gamma-aminobutyric acid (GABA).
The term “chemical messengers of the body” is frequently used to describe neurotransmitters.
The nervous system uses these molecules to send information between neurons or from neurons to muscles. The synaptic cleft is where two neurons communicate with one another (the small gap between the synapses of neurons).
Ligand-gated ion channels (LGICs) and G-protein-coupled receptors (GPCRs) on the postsynaptic neuron are receptors for neurotransmitter molecules that traverse the synaptic cleft. GPCRs
