Detailed explanation-1: -Some drugs, such as marijuana and heroin, can activate neurons because their chemical structure mimics that of a natural neurotransmitter in the body. This allows the drugs to attach onto and activate the neurons.
Detailed explanation-2: -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. Modulatory.
Detailed explanation-3: -Some drugs mimic neurotransmitters. Opioid drugs such as heroin and OxyContin, for example, chemically resemble the brain’s natural opioids sufficiently to engage and stimulate their specialized receptors.
Detailed explanation-4: -Agonists are substances that bind to synaptic receptors and increase the effect of the neurotransmitter. Antagonists also bind to synaptic receptors but they decrease the effect of the neurotransmitter.
