Abstract
This paper looks in detail at the different types of nervous tissue which include the central nervous system, the peripheral nervous system, the autonomic nervous system, and some special senses.

From the Paper
"The nervous system is divided into two main components the central nervous system (CNS) and the peripheral nervous system (PNS). The central nervous system consists of the brain and spinal cord and functions as the command center for the nervous system. The CNS coordinates the activities of the entire body. It receives and analyzes information through the PNS from the sense organs and other receptors throughout the..."

Abstract
The paper examines whether our conscious perception is an epiphenomenon of the activity of our central nervous system. The paper states that the argument is based on the fact that perception is shaped by cultural factors, meaning that people from two different cultures do not perceive the world in exactly the same way and explains that if conscious perception was not an epiphenomenon of the central nervous system, there would be no significant differences between cultures.

From the Paper
"In order to prove this point it is necessary to look at the nature of perception. Emily A. Schultz and Robert H. Lavenda in Cultural Anthropology define perception as, "The processes by which people organize and experience information that is primarily of sensory origin"(Schultz and Lavenda 1995: 139). What this means is that perception involves two distinct components. The first components are
the sensory organs themselves. The detect stimulus from the environment. However,sensory organs can only detect, they can't process the information. The central nervous system processes the information that the sensory organs have detected."

Abstract
This paper explores whether our conscious perception is epiphenious of the central nervous system. The paper argues that conscious perception is an epiphenomenon of the activity of our central nervous system.

From the Paper
"The relationship between conscious perception and the central nervous system is very controversial. The question that this essay will seek to answer is whether our conscious perception is an epiphenomenon of the activity of our central nervous system? This essay will argue that conscious perception is an epiphenomenon of the central nervous system. This argument will be based on the fact that perception is shaped by cultural factors. This means that people from two different cultures will not perceive the world in exactly the same way. If conscious perception was not an epiphenomenon of the central nervous system then there would be..."

Abstract
This paper briefly analyses the role of the nervous system, the physiological systems involved in arousal, the physiological and psychological effects of prolonged or intense arousal and the relationship between stress and disease.

From the Paper
"The CNS and PNS are further subdivided, the CNS as mentioned previously is divided into the brain the spinal cord and the PNS if further sub-divided into the somatic nervous system and autonomic nervous system. The somatic nervous system is responsible our voluntary actions through our skeletal muscles whilst the autonomic nervous system is responsible for involuntary functions including internal organs, muscles and glands such as heart rate and breathing rate, etc where levels of arousal are high due to these functions. The autonomic nervous system is further sub-divided into the sympathetic and parasympathetic nervous system."

Abstract
This paper examines in detail the effects Lysergic acid diethylamide (LSD) has on the Central Nervous System. Particular attention is paid to the body of research about the link between its interaction with serotonin receptors and the onset of hallucinations. Though one receptor in particular is believed to be the key, the lack of research on the subject in general precludes a definitive determination at this time.

Abstract
In this article, the writer notes that speech and language difficulties accompany a number of diseases of the central nervous system in adults. The writer points out that sometimes the speech difficulty might be the reason for seeking medical help, or it might be one of many factors that cause a person to seek medical attention. Speech difficulties might arise simultaneously with other symptoms, or they might arise at a different time. A myriad of problems fall under the category of speech and language difficulties. The writer discusses symptoms that range from slurred speech, slow speech and other problems that make it difficult to be understood to more serious difficulties, including a total loss of ability to speak at all. The writer looks at related causes, treatment and therapies. The writer maintains that regardless of the severity of the speech or language difficulty, or its cause, these problems make life difficult for patients and their caregivers.

From the Paper
"Parkinson's Disease is a dysfunction of the neurotransmitters between the nerve cells. Parkinson's disease destroys brain cells, resulting in a shortage of dopamine. The first signs of Parkinson's are typically subtle, such as softer or slower speech. As the disease progresses, tremors begin, which eventually worsen until hey cause considerable difficulty performing everyday tasks. Treatments to replace dopamine can help to slow the disease.
"Brain injuries are typically not listed under the category of disease. However, they are included in this research because they can cause certain forms of neurological dysfunction that can have an effect of speech and language."

Abstract
This paper explores how the autonomic nervous system functions. The structure of the autonomic nervous system and its impact on the performance of the body are clarified, and diagrams will be used to supplement this information.

Abstract
This paper provides concise descriptions of the 12 nerve pairs that originate from the brain, their functions, and how to pinpoint problems with each nerve. The paper is oriented toward treating the elderly, but much of the information is useful for all patients. The paper concludes with instructions for diagnosing the causes of hearing impairment and nosebleeds in elderly patients.

From the Paper
"Presbycusis is the sensorineural hearing impairment experienced by the elderly. There are several factors that lead to this condition. First, arteriosclerosis can diminish perfusion and oxygenation of the cochlea because of the insufficient blood supply caused by this condition. Reactive oxygen metabolites and free radicals build up, which can directly damage inner ear structures and cellular integrity of the inner ear. Diet and metabolism can contribute to the development of atherosclerosis; hence, a high fat, high cholesterol diet contributes to the decreased perfusion and oxygenation of the cochlea. Chronic exposure to loud noise can also cause a decrease in hearing. Medications and chemicals in the environment deemed toxic to the ear can cumulatively cause significant hearing loss in the elderly. Individuals with relatives that have hearing loss are at increased risk for presbycusis."

Abstract
This paper describes the structure and function of the bBZD/GABA/Cl complex in the CNS. It describes the action of benzodiazepines and how they work on the GABA receptor to produce their anxiolytic effects.

From the Paper
"Neurons in the brain communicate through chemical messengers neurotransmitters which are released by the signal-emitting neuron and bind to specific proteins. Excitatory glutamate and inhibitory GABA neurotransmitters, when bound to their respective receptors, increase or decrease the neuron's excitability. Excessive excitation causes panic attacks and excessive inhibition cases sedation. GABA is the major inhibitory neurotransmitter in the human central nervous system and participates in the regulation of neuronal excitability through specific membrane proteins of the neurons."

From the Paper
"In recent years life has been full of problems and difficulty. Human beings face difficulties in their work, in the home, and in everyday activity. Some of the most severe problems we are facing are AIDS and drugs. In this essay I will describe how drugs can be so dangerous and what they do to the nervous system.

A long time ago doctors invented drugs to help reduce the pain patients feel when they are sick or when they are having an operation. These drugs were very helpful and successful in reducing pain, but things got out of hand when people started using drugs when they were in good health.

Some people use drugs because they say it makes them feel better, and some other people say drugs make them forget their problems..."
