Difference Between Agonist And Antagonists

Chemical variations of drugs are referred to as ________________. Selected Answer: Answers: c. analogs a. antagonists b. designer drugs c. analogs d. agonists

An Opioid such as morphine act by attaching to specific proteins called opioid receptors, which are found in the mainly in the brain, spinal

There are many similarities and differences between neurotransmitters and hormones. Both neurotransmitters and the hormones are chemically secreted inside the brains. There our receptors for both hormones and transmitters and the target cells and the receptors induce biochemical responses from the individual depending on the type of neurotransmitter or hormone. Another similarity is that both hormones and neurotransmitters are vital for humans because they play an important role in digestion, metabolism, and

Stimulants can be used to speed up the central nervous system making a person fell more alert and aware of their surroundings. Depressants are the opposites and reduce the activity of the nervous system and produce a feeling of calm and/or “taking the edge off”. Hallucinogenics can be used to make an individual have hallucinations and have distortions in space and

When substances like Acetylcholine (Ach) and norepinephrine which are small- molecular neurotransmitters are released into the body they bind to receptors on tissue or neurons through our ANS and PNS system. Ach is released by many PNS neurons and some CNS neurons. In the PNS Ach is an excitatory neurotransmitter at some synapses, such as the neuromuscular junction where it binds to ionotropic receptors which open cation channels. Ach can also be an inhibitory neurotransmitter at other synapses, where it binds to metabotropic receptors while opening potassium channels. The enzyme acetylcholinesterase (AchE) inactivates Ach by splitting into acetate and choline fragments. Norepinephrine (NE) is a biogenic amine; most biogenic amines may cause

1. first by the conditions that they are used to treat, and then by their mechanisms of action

There are few psychoactive drugs more addictive than the opioid family. This term refers to any substance, natural or synthetic, that binds to the brain’s opioid receptors, which are the parts of the brain responsible

Endogenous opioids work together to modulate pain by activating different types of opioid receptors (μ, δ, κ, ORL1). In contrast, most exogenous opioids are primarily using μ receptors to dampen pain. T exogenous opioids will disproportionately activate feelings of euphoria and breathing by activating every μ receptor in the brain/spinal cord to successfully diminish the sensations of pain. There is a relationship between this disproportionate activation and our problems of addiction, dependence, and overdosing.

According to National Institute of Drug abuse, addiction is defined as a chronic, relapsing brain disease that is characterized by compulsive drug seeking and use, despite harmful consequences (2014). Opioids are natural or synthetic compound that mimics properties of natural narcotics. It is a pain reliever that works by tying to opioid receptors, which are found principally in the central nervous system and the gastrointestinal tract. The receptors intervene

These non-opioid drugs have therapeutic effect and they also have side effects as well. These

Oxycontin is classified as an opioid or narcotic pain relieving medication, called opioid analgesics. The Oxycontin molecules work by changing the pain response generated by the central nervous system. It works by interacting with specific proteins called receptors as shown in Figure 1. These receptors are found on cell surface, in the brain, gastrointestinal tract, spinal cord and other organs in the body (Columbus, 2008).

Mechanism: Although the exact mechanism of action is not known, ketamine appears to be an agonist at CNS muscarinic acetylcholine-receptors and opiate-receptors. Ketamine

In this experiment we will be dealing with two chemicals that intend to inhibit a nerve impulse.

Agonist- These are usually found in pairs and the agonist is usually the main contributor out of the pair. Which they provide significant movement to help complete a movement needed e.g. bicep curl. The bicep curl causes a flexion which would mean that the contracted muscle, the bicep would be the agonist and during extension the agonist would be the triceps. This means that the agonist would constantly be contracting.

I think it was interesting to learn about the difference between drugs that are stimulants and depressants. I have always thought that all drugs have similar effects on the body such as producing an euphoric feeling, which I assumed is what attracted drug addicts in the first place. It is also very interesting to see all the detrimental effects that drugs have on the body, but drug addicts are still willing to ingest it just to have a temporary, pleasurable feeling. Depending on a person’s background, they could be more prone to developing a drug addiction. Biologically, if one of your parents is an addict, you are more likely to become one. Psychologically, depending on your viewpoint of the world or how you were raised, you may believe that
