The Myelin Sheath And Its Effects On The Human Body

MS is characterized by the destruction of myelin, inflammation in the CNS and the formation of lesions in the CNS.

No single test detects MS, which makes it difficult to diagnose. Symptoms can mimic those of a number of other conditions and they can change depending on the area of the central nervous system that

Multiple sclerosis, or MS, is a disease of the central nervous system. The central nervous system is made up of the brain and spinal cord. Both have nerve fibers that are wrapped in a myelin sheath. In MS, the myelin sheath becomes inflamed and gradually is destroyed. With the destruction of the myelin sheath comes an array of symptoms that may include numbness or tingling, balance problems, weakness, muscle spasms, and blurred vision.

The father of neurology, Dr. Charcot, examined the brain of a deceased patient because the patient had a tremor unlike anything he has treated before. He noticed plaques or abnormal clusters of chemically sticky proteins that build up amongst nerve cells. He also described the patient’s symptoms and changes in the brain that accompanied the plaques; this was the first description of multiple sclerosis. In England in 1873 and in the United States in 1878, multiple sclerosis was first recognized based off of Dr. Charcot’s description of the disease. In 1916, Dr. James Dawson performed autopsies on brains of patients who died with multiple

While this may sound like an autoimmune disease, scientists are still unsure about what antigen the immune cells are attracted to attack, meaning it is “immune-mediated” as opposed to “autoimmune” (Evidence). This, like many components to MS, remains a mystery, and researchers are still discovering and advancing what we know about the disease.

Multiple Sclerosis (MS) is a condition where myelin forms scar tissue and disfigures nerve impulses. This is an example of a deviation from normal physiology found in the nervous system. MS is the result of the immune system atypically attacking myelin and nerve fibers within the central nervous system (CNS). When the myelin and nerve fiber are damaged, it can cause the signal to be disturbed or disfigured. The damaged scar tissue (sclerosis) gives the disease its name. The symptoms of MS can range anywhere from pain and fatigue to tremors and

Multiple Sclerosis is an autoimmune disorder affecting movements, sensation and bodily functions. The cause of MS is by the myelin sheath being destroyed in the brain and spinal cord. The immune system attacks myelin sheaths which is a fatty substances that surrounds the nerve axons that makes it possible for the transmission of nerve impulses. When the myelin sheath are destroyed the nerves impulses that are being triggered to the brain and spinal cord get out of disrupted that provoke the messages to become slower and less efficiently. There are four types of MS people could experience which are Relapsing-remitting multiple sclerosis (RRMS), Secondary –progessive multiple sclerosis (SPMS), Progressive-relapsing multiple sclerosis (

Multiple sclerosis is a progressive disease that affects the central nervous system, which includes but is not limited to the brain, spinal cord, and optic nerves. Within the CNS the immune system attacks myelin sheaths, which are fatty membranes surrounding the axon of a neuron. Overtime the damaged myelin sheath forms scar tissue called sclerosis, which is what gives the disease its name. When scleroses are formed on the myelin sheath, nerve impulses that travel to and from the brain and spinal cord are dramatically slowed and sometimes even completely blocked. Consequently the muscular system is not able to function properly, which is what gives MS such crippling symptoms.

Multiple sclerosis (MS) is an autoimmune disorder that causes the immune system to attack myelin sheath causing neurological damage to areas of the brain and causes neurological deterioration. In the brain the myelin sheath is involved with what allows for communication between brain and the body. As the disease progresses the sheath deteriorates the neurons where the myelin sheath is found is damaged, causing a break or loss of information when the brain is trying to communicate with the brain. As the central nervous system (CNS) is deteriorating it causes permanent damage that is incurable. The symptoms are not as

Multiple sclerosis is an autoimmune disease that majorly affects the brainand the spinal cord (A.D.A.M. Medical Encyclopedia, 1). The disease affects the central nervous system and thus causes limitations of individuals to carry out various activities. In multiple sclerosis, the myelin sheath that covers nerve cell axon is destroyed causing inflammation (MediResource Inc., 1). Destructionof the membrane leads to slowed conveyance of signals from the spinal cord to the brain, which as a result leads to reduced response to different stimuli. Inflammation of the nerve occurs mostly when the immune cells from the body attack the nervous system. The inflammation is not only limited to the spinal cord, but sometimes extends to

So what exactly is Multiple Sclerosis? Multiple Sclerosis is an autoimmune disease which affects the central nervous system. The central nervous system consists of the brain, spinal cord, as well as the optic nerves. The simplified meaning of the diseases name is Multiple scar tissues or lesions. A person with multiple sclerosis develops numerous lesions or scars on the brain and spinal cord due to the effects of an overworking immune system. When the immune system overworks, it attacks the “myelin— the fatty substance that surrounds and insulates the nerve fibers — as well as the nerve fibers themselves”(National MS Society). Myelin is essentially the coating that protects your nerves; when trying to understand what myelin is, one can compare the similarities of myelin to the coating that covers electrical wires. After the immune system attacks and damages the myelin,

Multiple sclerosis is a disease of the central nervous system and the disease functions by using the immune system to attack the body in the CNS targeting the nerve fibers. It focuses on the myelin sheath that covers the nerve fibers damaging them and scaring the fibers. This will cause a disruption of communication that is shared between the brain and the body and eventually will be permanent damage. This process is called demyelination. This disease is difficult to diagnose but if you start seeing signs and symptoms go to the doctor to get professional medical treatment or advice to slow down the process of

In the article, “Multiple Sclerosis”, a group of medical doctors provided detailed information about clinical course, diagnosis and treatment of MS. According to this article, MS is an autoimmune disease of the central nervous system and spinal cord, which attacks the myelin, the protective covering of the nerves. Signs and symptoms differ from patient to patient. In the early stage, the disease manifests in tingling, impaired sensation, vision problems but as it progresses some of the patients lose the ability to walk independently. Eventually, the disease causes the nerves to deteriorate or become permanently damaged. Neurologists, doctors who care for MS patients, diagnose the disease through a neurological examination and MRI scan. Not

Multiple sclerosis (MS) is a demyelinating disease which affects nerves in the brain and spinal cord which results problems in muscle movement, balance and vision. The nerve fiber in the brain and spinal cord are surrounded by layer of protein called myelin which help to protects the nerve and helps electrical signals from the brain travel to the rest of the body. In case of multiple sclerosis the tissue which is affected is myelin sheaths. During multiple sclerosis something goes wrong with immune system and immune system starts attacking myelin sheaths as they recognize them as foreigner bodies. During macrophage myelin sheaths is engulf and they are presented as foreign bodies to the T-lymphocytes cell which produce antibodies and destroy

Autoimmune disease is a disease where the body’s immune system attacks and damages its own body tissues. The immune system may start producing antibodies that will attack its own body tissue instead of protecting and fighting infections in response to an unknown triggering mechanism. Multiple Sclerosis (MS) is a type of autoimmune disease in which the myelin sheath that covers axons and speeds up the transmission of nerve impulse in the brain is damaged or destroyed. The word Multiple refers to many areas and Sclerosis refers to the scar of the myelin sheath. The disease affects the central nervous system which are the brain and spinal cord. When the myelin sheath is damaged, nerves cannot conduct the electrical impulses efficiently.
