Central Nervous System Part Of The Brain
5,865 wordsWhen we discuss our brain, we usually focus on the brains ability to think. That task alone is extremely complex and involved, but the brain also has many other tasks. Most of the time the brain is on autopilot, meaning that most of the activities preformed are just automatic. Our five senses; sight, sound, touch, taste, and smell, are automatically preformed in our brains. We don't have to think about how something sounds, we just hear it and we then interpret that sound. The largest area of ou...

Patients With Als Fact That Glutamate Skin
641 wordsThis theory is based on the fact that glutamate, an amino acid present in proteins, can cause neuronal cell death when present in high concentration. The specific evidence for the excitotoxic theory comes from the demonstration of decreased levels of glutamate in ALS spinal cord, with the assumption that glutamate must have been released and must have been present in high concentrations that would have been toxic. In addition, there is a decreased ability of glutamate to be taken up in fractions...

Central Nervous System Peripheral Nervous System
1,382 wordsThe ability to regenerate the tissues of the human central nervous system (CNS) is one of the greatest projects undertaken by biomedical engineers today. With this eventual technology, permanent paralysis and blindness due to CNS injury will be a thing of the past. Central nervous system injuries will be repairable, an idea that was, until recently, just a fanciful dream, something out of a science fiction novel. In the last few years, however, giant strides have been made to make the idea of CN...

Central Nervous System Peripheral Nervous System
1,365 wordsThe definition of Brain as given in the Taber's Cyclopaedia Medical Dictionary is "Brain- a large soft mass of nerve tissue contained within the cranium; the carnal portion of the central nervous system. The anatomy of the brain is composed of neurons (nerve cells) and neuroglia or supporting cells. The brain consists of gray and white matter. Gray matter is composed mainly of neuron cell bodies and is concentrated in the cerebral cortex and the nuclei and basal ganglia. White matter is composed...

Infected With Hiv Hiv Virus
1,249 wordsThe Impact of HIV/AIDS on Childrens Cognitive Abilities HIV in a child that is passed from the mother is a very unfortunate disease. The child has no chance before it is even born. The virus sets in at an extremely early time when there is not even an immune system in effect. A child can be affected in many ways after being infected with the HIV virus. Although, most symptoms will be extremely similar to an adults symptoms. The largest factor contributed to a change in symptoms is how the adult ...

Serotonin Reuptake Inhibitors Obsessive Compulsive Disorder
3,264 wordsBrain Chemistry and Recent Advances The mysteries surrounding the complexity of the brain and how it works has led scientists in diverse fields to search for answers. Chemicals in the brain and the reactions that take place are being understood now more than ever due to continuing research in genetics, pharmacology, and mental illness. Study and research in genetics has helped identify some of the genes involved in producing, receiving, or sending certain chemical reactions, the way they work, a...

Fatty Acids Petri Dish
4,956 wordsPlan The initial variable to be considered will be the effect that caffeine and temperature has on the heart beat and if it has a direct or indirect effect on the daphnia's lifespan. If there is enough time to consider a second variable however, the effects of a temperature or alcohol on the daphnia's body system will also be considered alongside the initial variable of caffeine. These will then be slotted into the same graph which will show us how the figure correspond to the results. In order ...

Lancaster Nitric Oxide, or NO, its chemical representation, was until recently not considered to be of any benefit to the life processes of animals, much less human beings. However, studies have proven that this simple compound had an abundance of uses in the body, ranging from the nervous system ...

Central Nervous System Spinal Cord
888 wordsSpinal Cord Regeneration Spinal cord injury can occur in many ways ranging from gunshot wounds, stab wounds and also bone displacement. These circumstances can lead to the death of neurons, and the demyelination of axons which causes some loss and damage to neurons. As Hudgins (1998) reports after a primary injury such as above, secondary injury occurs 30 minutes after and also that secondary injury is when the most critical damage occurs. This is when there is hemorrhaging in the gray matter of...
