Psy 430 Essay 4 –Methamphetamine Due: 10/18/12 Drugs are used with the purpose of altering one’s state of consciousness or being. Often, drugs may be abused because a person is seeking a pleasurable high. Not only may people develop a psychological dependence on a drug, but they also develop a physical dependence due to altered brain structure. Drug use not only has a direct effect on the brain and body, but often may lead to a destructive lifestyle involving violence, crime, poverty, and poor health. Methamphetamines are stimulants known to have a devastating effect on its users psychologically and physically.
The hippocampus on the other side is responsible for the production of corticosteroids (chemicals that produce physiological responses to stimuli). How the mind creates memories is controlled by the hippocampus. So as to work efficiently, the amygdala and the hippocampus rely on each other greatly. The amygdala regulates the responses to stimuli and the hippocampus uses these responses in the formation of both short-term and long-term memories. Damage to the amygdala or hippocampus causes loss of emotions and memory respectively.
That is why we are more susceptible to infections. The stress hormone corticosteroid can suppress the effectiveness of the immune system (e.g. lowers the number of lymphocytes). Stress can also have an indirect effect on the immune system as a person may use unhealthy behavioral coping strategies to reduce their stress, such as drinking and smoking. Stress is linked to: headaches; infectious illness (e.g.
Because of this fear of diseases, she thinks that she could get AIDS from a small speck of blood on others. These catastrophic thoughts will help maintain OCD because there are exaggerations of the danger they are in, causing them to constantly act upon them. The cognitive explanation helps to explain how OCD is maintained, e.g. hypervigilance,
When the mucus becomes abundant this triggers the cough reflex. C.) Which structures found in the terminal bronchioles and particulate matter? In the terminal bronchioles and alveoli there are macrophages, these would normally protect Cari’s lungs from infectious bacteria and particulate matter. D.) How would the resistance of Cari’s airways be affected by excess mucus and fluid in her lung? Cari’s airway would be affected by excess mucus and fluid buildup because the build up would cause resistance in her lungs due to the small diameter of space that is available.
In atrial fibrillation, a problem with the heart's electrical system the atria to quiver, or fibrillate. The quivering upsets the normal rhythm between the atria and the lower parts (ventricles) of the heart. The lower parts may beat fast and without a regular rhythm. Atrial fibrillation is dangerous because it greatly increases the risk of stroke. If the heart doesn't beat strongly, blood can collect, or pool, in the atria.
1. Explain how the use of substances alters a person’s state of consciousness, including depressants, stimulants, and hallucinogens. Include in this explanation what happens to the neurotransmitters and body chemicals as well as how you might recognize if a person at work or in your family is in an altered state of consciousness due to the influence of drugs. Drugs can either enhance a particular neurotransmitter’s effect (an agonist drug) or inhibit it (an antagonist drug). Depressants act on the central nervous system to suppress or slow bodily processes and to reduce overall responsiveness.
The cochlea is full of liquid and lined with cells that have tiny hair cells on them which are the start of the auditory nerve. The vibrations make ripples in the liquid that is in the cochlea and the ripples move the very tiny and sensitive hair cells. The hair cells carry this information through the auditory nerve to the brain which then interprets what we actually hear. The semicirular canals control our balance, each of the three canals sense a different movement ie; upwards, downwards, sideways. If we spin around quickly the fluid in these canals moves around quickly and if we then stop we can feel slightly dizzy until the fluid settles down again in the canals.
IVIG can potentially interfere with these autoantibodies as well as suppressing the response to proinflammatory cytokines, which are important in the mechanisms of CRPS pain and hyperalgia, in the peripheral and the central nervous systems. Pathophysiologic findings support a mechanism that may explain the results of this
The expectation is that the oil is going into the blood stream to help elevate a particular aliment. As mentioned above, sometimes peppermint is used in message therapy to help elevate pain. Along with the benefits, essential oils can be dangerous if not used properly. The oils are not meant to be used in full strength. Many essential oils are required to be diluted before they can be applied to the
