The Central Nervous System is composed of the brain and the spinal cord and one of it’s primary functions is to send out messsages to the rest of the body. One chronic illness that affects the Central Nervous System is Multiple Sclerosis. Roughly 2 million people througout the world have been faced with this disease‚ and “in the United States‚ it is estimated that 450‚000 people are affected‚ with 10‚000 new cases per year” (Goodman & Fuller 772). This disabiling condition has been found more prevelant

Central Nervous System In the movie the Wizard of Oz‚ the Scarecrow desperately wanted a brain. He opened his lips‚ blinked his eyes‚ shook his head and said‚ “I haven’t got a brain‚ I’ve only got straw.” The reason for the emphasizing of his actions is because without a brain‚ those functions are not possible. The brain is the center of the entire body. It controls what we do and how we do it. The brain is the center of the central nervous system along with the spleen. It consists of 100

THE CENTRAL NERVOUS SYSTEM Every behavior begins with biology. Our behaviors‚ as well as our thoughts and feelings‚ are produced by the actions of our brains‚ nerves‚ muscles‚ and glands. In this chapter we will begin our journey into the world of psychology by considering the biological makeup of the human being‚ including the most remarkable of human organs—the brain. We’ll consider the structure of the brain and also the methods that psychologists use to study the brain and to understand how it

THE NERVOUS AND THE ENDOCRINE SYSTEM. Humans need both the Nervous and the Endocrine systems basically because they do different things in different ways. They both have a co-ordination role and send instructions to other parts of the body. The nervous system does this by way of neurotransmitters‚( chemical messengers)‚ which are able to get messages through at very high speeds‚ and the endocrine system by way of hormones‚( also chemical messengers)‚ which are released from glands and travel

1.) Name and describe the function of each part of a neuron. What is a neuron? The neurons are the basic elements of our nervous system. You can call them specialized cells in which includes the units of info-development in our brain‚ are very responsible for the perception and the transportation of information. Each part of the neuron has a very important role providing information in the whole body. The most important parts of a neuron are: a cell body‚ dendrites‚ and an axon. • Cell Body‚ also

Disorders of the Nervous System The way we think‚ our emotions‚ and the ability of our body to tell itself to move all connect back to the nervous system. If one part is not connected to another or if something never developed properly it can create a major problem. Disorders can occur within the brain or can be malfunctions of the nerves. Disorders can range from Palsy and Parkinson’s in which symptoms are movements such as tremors to Alzheimer’s which is mental deterioration and loss of memory
