The Intimate Relationship Of The Nervous System

The nervous system is made up of basic units called neurons. The main role of the neurons is to receive, integrate and transmit information throughout the body. There are some neuroglial cells found in nervous system aswell which provide support to the neurons by giving protection and nourishment Neurons have nerve processes that looks like finger like projections extended from the nerve cell body. They also contain axons and dendrites which enable them to transmit signals throughout the body. Normally, axon carry signals away from the cell body and dendrites carry signals toward the cell body according to Regina Bailey (2013). Neurons have three different shapes: bipolar, unipolar and multipolar where bipolar has two neuronal processes coming out of the cell body, unipolar has only one neuronal process coming out of the cell body and multipolar has many neuronal processes coming out of the cell body.

Dzevdet Smajlovic, professor from the Department of Neurology at the University of Tuzla in Bosnia stated that

The progress of neuroscience has been significant in the past 500 years. and with the advance of technology, there is yet a multitude of chapters left to write in the history books of neuroscience. The book The Tale of the Dueling Neurosurgeons: written by Sam Kean was an engrossing and captivating read. It gives the reader a better appreciation for the growing pains of neuroscience and provides an educational, albeit entertaining overview of the anatomy and physiology of the brain and nervous system. From the early life and discoveries of Santiago Ramón y Cajal and his fascination with Golgi’s method la razione nera, which allowed Cajal to deduct after observing

Neurons, nerve cells, have three basic parts: the cell body, dendrites, and axon. Neurons transmit signals to other nerve cells and throughout the body. They are simple components in the nervous system. The cell body includes the nucleus, which is the control center of the neuron. The dendrite branches off the cell body and receives information. The axon is attached to the cell body and sends information away from the cell body to other cells. When the axon goes through myelination, the axon part of the neuron becomes covered and insulated with fat cells, myelin sheath. This increases the speed and efficiency of information processing in the nervous system. Synapse are gaps between neurons, this is where connections between the axons and dendrites.

Write a brief description of the three slides (Neuron, Spinal Cord Smear and C.S of Myelinated Nerve Fibers) as though you were explaining it to someone who cannot see the slide.

Doctors need a sure way to diagnose the disease before treatment or studies can be done. The diagnosis is an autopsy of brain tissue examined under a microscope. In addition, medical history,

Research is being done on remyelination since it was not a procedure that was having long term effects and often would fail.Instead it could leave patients with a scar and sometimes even worse then they started. Much research is being done to comprehend step by step how this procedure is carried out, so that remyelination can be adequate and

___________ is a stain used in brain image analysis that can illustrate the number of neurons.

Our focus for this week’s lab was the vertebrate nervous system. The nervous system is composed of two divisions called the central nervous system and the peripheral nervous system. Within these two divisions there are three types of neurons that allow us to recognize changes in our environment and help us to respond accordingly. The three neurons that are found are called sensory neurons, interneurons, and motor neurons.

The brain is a unique organ, it allows us as humans, for example to imagine, speak and perform a lot more complex functions. To function well as a complex organ, the brain has a lot of cells. The brain consists of neurones and glia cells. Neurones observe changes from the environment, communicate these changes to other neurones and issue commands to the body to react on these changes. Glia cells give the neurones among other things protection and support. Neurones are really small cells composed of two parts: the soma, which contain the cell nucleus and neurites, which are projections from the soma. There are two different types of neurites, the axon and the dendrite. Dendrites receive signals to transfer to the neurones and axons carry the output of the neurones. Figure 1 gives a schematic overview of a neuron and shows the dendrites, cell body and axon. This essay will discuss the structure of neurones and the different types of neurones further in detail. It will start with the structure of a typical structure of a neuron and then the different types of neurones, the sensory-, motor- and interneurones. (Bear, M.F. et al. (2007))

Chapter one THE NEUROLOGICAL DIAGNOSIS It is useful to think of the neurological diagnosis as a three step process. The first step is to make a topographical diagnosis, i.e. to locate the lesion that is responsible for the patient’s symptoms, because almost every neurological disorder has a tendency to occur in a specific part or parts of the nervous system. For example, the plaques of multiple sclerosis have a predilection for the visual pathways, cerebellum, brain stem and spinal cord. Therefore, localisation of a lesion to a specific part of the nervous system narrows down the number of possible diagnoses. However, since several diseases may affect the same part of the nervous system the second step involves a further diagnostic workup to differentiate between the various possible disorders.

Within the human anatomy, an intricate and complex network of specialised nerve fibres and neurons works in collaboration with the central nervous system and peripheral system, designed to carry out the various actions humans perform every day. The nervous system is also known as the master control unit of the human body, as it operates other major functions such as the circulatory and respiratory systems (Jakab, 2006). It is composed of the central nervous system (CNS) and the peripheral nervous system (PNS). The neurons established within the various sections of the nervous system, is structured with three main parts: a dendrite which is a cluster of branches that operates by receiving information from the

Even though the brain is the major control center if the body, its job would not be possible without the spinal cord. The spinal cord is the major organ that helps information travel between the body and the brain. Nerves branch in the peripheral system from, either the brain stem or spinal cord, each nerve attaches to a specific area of the torso and limbs it 's responsible for communication to and from those regions. There are three very important

In 1935, Fulton presented his findings at the second annual international neurological conference in England, where Egas Moniz also happened to be in attendance. When Moziz met Fulton in London, Moniz had already nearly won the Nobel Prize, for developing a revolutionary innovation in neurosurgery at the time. Back in 1925, Moniz found a noninvasive way to diagnose brain tumors. Devising a plan called cerebral angiography, in which by injecting sodium iodide into the carotid artery of a patient’s neck, the solution would flow through the bloodstream, causing blood vessels to appear opaque when viewed in an x-ray. Moniz’s technique was a huge breakthrough in brain imaging, allowing doctors to find problems in the brain’s blood vessels, caused

The organs of our body are controlled by many systems in order to function correctly and efficiently in order to survive within the environment we live in. These include the heart, stomach and intestines and other vital organs and body systems. All of the systems in our body are regulated by a part of the nervous system called the autonomic nervous system (ANS). The ANS is part of the peripheral nervous system and it controls many organs and muscles within the body. Rather bizarrely we are unable to determine or feel its presence in our bodies as it is working involuntary, as a reflexive manner. A common example of this involuntary action is best understood when
