Central nervous system

Therapeutic drugs that are needed to target the central nervous system need to work to cross the blood brain barrier, often times failing. There are a few different ways scientists of discovered to help administer the medicine. One technique is direct injection. This has several draw backs because it is complex…

Methamphetamine and its Effects on the Body and Brain Methamphetamine (n-methyl-1-phenyl-propan-2-amine) has a molecular weight of 149.237 g/mol and is an addictive man-made stimulant affecting the central nervous system (Methamphetamines: An Overview, n.d.). There are two different types of methamphetamine: l-meth (Levo-methamphetamine), and d-meth (Dextro-methamphetamine), which is the more common form. It is 2 to 10 times as physiologically active as l-meth (Crystal Meth Facts, n.d.).…

a part of the central nervous system and it can be classified into the hindbrain, midbrain, the forebrain and the brain stem right below the brain. Inside the midbrain, there is the cerebral cortex which consists of the temporal, occipital, parietal and frontal lobe. Their functions are processing auditory information; processing visual information; processing sensory information and order complex cognitive behaviours respectively. Same inside the midbrain, there is the limbic system which…

“The virus can enter the peripheral nervous system directly and migrate to the brain or replicate within muscle” (www.medicalnewstoday.com). “The rabies virus is a rod-or bullet-shaped single-stranded negative sense, un-segmented enveloped RNA virus” (www.ncbi.nlm.nih.gov). “The virus genome…

In this study, it was found that ALS patients have a deficiency of glutamate transporter proteins (Watanabe et al., 2001). These proteins carry free glutamate into surrounding astrocytes, a star-shaped neuralgia cell of the nervous tissue. Normally, free glutamate would be directly removed (Fig. 2). In their research, a key protein called glutamate transporter 1 (GLT-1) is found to be deficient in the brains and spinal cords of some patients who had died of ALS. GLT-1 is an…

Human Nature and Determinism: What is the Provenance? As human intellect and history have progressed, many differing speculations of human nature and what determines it have been formulated. These types of philosophies took root as early as we can trace, with historical figures such as the Ancient Greeks forming their own deliberations concerning human nature and its motives or lack thereof. There are many conjectures on this subject, but prominent forms of determinism are historical…

disease, and current treatments aim to ease the symptoms and slow down the onset of the disease. There are four factors that are believed to cause the onset of Multiple Sclerosis. The first factor is that the immune system malfunctions and starts to attack the central nervous system. This results in damage to the myelin sheath and the axon (Goldenberg, 2012). The second factor is genetics. Scientist suggest there may be genes that play a role in multiple sclerosis, and that a child has a 2-5%…

children. Dominant gene defects are:- • Tuberous sclerosis (a disorder affecting the skin and nervous system) • Achondroplasia (dwarfism) • Huntington’s chorea (a disorder of the central nervous system) If both parents carry a single recessive gene defect children have a 35% chance of being affected. Recess gene defects are:- • Cystic fibrosis (a genetic condition in which the lungs and digestive system become clogged with think sticky…

Since temazepam is classified as a benzodiazepine, I was curious as to what this type of drug does within the brain and its effects throughout the body. A benzodiazepine works as a type of mild sedative within the central nervous system. The molecule acts on the central nervous system by increasing the effects of GABA, which is…

neurological problem that affects many people from the ages 20-40, it is a disease of the brain and spinal cord, and that is multiple sclerosis. According to the national MS Society, multiple sclerosis is an unpredictable and disabling disease of the central nervous system that disrupts the flow of information within the brain, and between the brain and body. The causes of MS are unknown but it is believed by scientists that infectious agents may play a role. There are many ways to treat…
