Myelin

is normal. Babies have different sleepig habits and require sleep at different times such is the case with Thomas sleeping at 9pm some nights and at 7pm other nights (Raisingchildren.net.au, 2016). Meylination also known as the myelin sheath forms around axons. This myelin sheath helps the nerve cell in the body transmit information faster without loosing any signals along the way conecting other cells to the synapses (Berger, 2008). As we age myelination is forming in the frontal lobe which…

part. Those who have family history with the condition are also more likely to develop MS. It is believed to be an autoimmune disease, in which the body's immune system produces an abnormal response, attacking its own cells and tissues. In MS, the myelin, a fatty substance that surrounds, protects and insulates axons, is destroyed. This causes the electrical signals that travel along the nerve…

Upon development, the nervous system wires itself completely – an impressive feat considering the millions of connections and neurons in the body. However perhaps even more impressive is the ability of the nervous system to restore neuronal connections after injury. This is particularly advanced in frogs, fish and invertebrates as once an axon is cut in the central nervous system, the regeneration allows full functional recovery whereas in the mammalian central nervous system full recovery is…

Multiple sclerosis (MS) is a muscular disease that affects the central nervous system (CNS) which consists of the brain and the spinal cord. This disease was discovered by Dr. Jean Martin Charcot. Eventually, improvements in microscopes helped doctors in the search of understanding the disease. In 1916, a Scottish doctor named James Dawson was able to clearly describe the inflammation after viewing the brain cells of a patient with multiple sclerosis through a microscope. Over the years,…

it was only generated from axons. The action potential speed is constant as it moves down an axon and depends on factors such as the diameter of an axon and the presence of myelin. Larger myelinated axons tend to be faster and the speed of action potentials can range from 0.2 meters per second to 120 meters per second. Myelin is a fatty substance that help in speeding up action…

Krabbe disease is named after a danish doctor knud haraldsen krabbe he lived until 1885 to 1965.Krabbe disease is inherited disorder that destroys the protective coating (myelin) of nerve cells in the brain and throughout the nervous system. There’s no cure for krabbe disease.However, stem cell transplants have shown some success full in infants who are treated before the onset of symptoms and in some older children and adults. krabbe disease is named after a danish doctor knud haraldsen…

Myelin promotes efficient neural signal transmission along the nerve cells. The appearance of the developing brain in structural MRI differs significantly from the appearance of the mature adult brain. The myelinated WM in T1-weighted MRI increases in intensity…

Breastfeeding infants instead of using formula can improve brain development in many different areas. In the article Breastfeeding Boots the Brain Development of a Baby, the article states that breastfeeding can help develop white matter in the brain of infants. This growth in white matter also lead to better performance in areas like language, visual perception and motor control. White matter is a type of tissue in the brain and spinal cord made up of nerve fibers, some may even characterize…

T cells also have effect on Natalizumab in patients with multiple sclerosis. Natalizumab is a monoclonal antibody that reduces the formation of acute lesions in the central nervous system. Bornsen et. al revealed the influence that natalizumab has on circulating CD4+ T cells in multiple sclerosis. The recurrence of multiple sclerosis happens when there are abnormalities in activated macrophages, CD4+ and CD8+ T cells in the central nervous system. Very-late antigen formed on surfaces of most…

Discussion over the Bodies Different Internal Bodily Functions In this paper I will be noting the inquiries that was doled out from this week task. I will talk about the relationship between conveyance of muscle fiber sort and action. I will also clarify how practice preparing alter or change a man 's fiber-sort conveyance. We additionally need to portray the systems by which muscle glycogen is separated to glucose for use in glycolysis. Depict how a nerve motivation is transmitted along its…
