Outline Multiple Sclerosis is unique and different from other diseases due to its causes, symptoms and treatment. I. Many causes can lead to multiple sclerosis but the main cause still unknown. A. One of the causes is Genetics 1. MS seems to be inherited, or a person may have abnormal genes when he was born. B. Environmental factors raise the risk of having Multiple sclerosis 2. Smoking and the deficit in vitamin D and other environmental factors can lead…

About 20% volume of the mammalian central nervous system comprises of an extracellular matrix that includes proteins, proteoglycans, and glycosaminoglycans (Bignami A et.al 1993). Evolving evidence indicates that the organization and composition of this matrix change throughout the course of normal aging, during neurodegenerative diseases and following central nervous system injury and that these modifications influence a diverse range of cellular behaviors. The central nervous system…

1. INTRODUCTION Our mind comprises of 100 billion neurons and a trillion glia [1], which is a conservative structure of tissue measuring approx 3 lakes. The mind houses our mindfulness, our gathered encounters isolated and broke down and interpreted into a code by combined fleeting projections, and put away in a system including the working of cerebrum. Stroke has enhanced our present comprehension of the cerebrum more than some other ailment. There are numerous routes in which neurological…

part of the brain which is the part of our brain that control memory. An elderly person will start to forget information that they knew their entire life such as books, places and most importantly names a. “The brain has 100 billion nerve cells (neurons). Each nerve cell connects with many others to form communication networks. Groups of nerve cells have special jobs. Some are involved in thinking, learning and remembering.” b. http://www.alz.org/alzheimers_disease_what_is_alzheimers.asp…

Dopamine Receptor D2 The D2 dopamine receptor has an extremely important function in the nervous system. The D2 receptor is metabotropic: it is coupled with a G-Protein linked receptor. This implies that a dopamine receptor is in the G protein-coupled receptor class. They are prominent in the vertebrae of the central nervous system. The synthesis of a dopamine receptor is extremely complicated. The subtypes of receptors differ in function and structure during DNA synthesis by the absence or…

appropriate responses. The cross communication between the body and mind relies on the chemical mediators, which involve electrical signals along the nerve pathways. These electrical signals are converted into chemical signals at the synapses between neurons. Therefore, the chemical messengers communicate with the nerves, brain, and other parts of the immune system. As a result, the chemicals released by the nerve cells act as the immune cell signals and allow hormones to travel from the body to…

destroys memory and thinking skills, and eventually the ability to carry out the simplest tasks,” (Fact). Alzheimer’s disease is the most common form of dementia (Association). It causes disturbances in metabolic processes that are vital to keeping neurons healthy. These disturbances cause nerve cells to stop working, lose connection with other nerve cells, and eventually die. This causes memory loss, behavioral issues and problems with critical thinking (Fact). Causes Amyloid plaques are…

Nervous tissues have neurons and nerves that support cells. Its function is to send impulses to different areas of the body. It reacts to stimuli and conducts impulses to different organs in the body that carry a response to the stimulus. Nerve tissues are in the brain, spinal cord and peripheral nerves which are all made up of neurons. http://www.msnucleus.org/membership/html/k-6/lc/humanbio/4/lchb4_3a.html Cardiovascular system The cardiovascular system is made up of your heart, your blood…

prominent part of the forebrain, consisting of multiple layers of cells that are located on the exterior of the cerebral hemisphere. These layers of cells consist of either white matter or gray matter, as well as the axons that transfer information with neurons, either through the corpus callosum or the anterior commissure, and connect both the right and left hemispheres of the brain (Kalat, 2013). The cerebral cortex contains six layers of cell bodies, called laminae, which differ in both…

repetitive temporal coordinated action of muscles and joints. Whenever there is a brain injury, it stimulates re-initiation of axonal sprouting processes. Every specific motor learning task modifies dendritic and synaptic morphology of motor cortex neurons in a particular way. Simple repetitive motion or strength training motor tasks do not induce plasticity in the cortex. On the contrary, tasks that require acquisition of new motor skill lead to neuro-physiologic and neuro-anatomic changes in…
