Well have you ever wonder what Multiple Sclerosis? Today i'm going to explain to what MS(Multiple Sclerosis) is so I hope that you enjoy. What is Multiple Sclerosis? Ms is an Autoimmune disorder. When the disorder progresses the nerves will be damaged and so the damaged is caused by inflammation. Another thing is the cells that were protected by a layer will be damaged as well. So when you have the damaged cell this will lead to the brain and the spinal cord. So that is what MS is. Well what
brain barrier, provides nutrients, and repairs scar tissue • Microglia- act as part of the immune system, remove waste material and viruses and fungi from the brain • Oligodendrocyte- forms myelin sheath in the central nervous system cells, won’t repair damaged axons, exists in the CNS • Shwaan cells- form myelin sheath outside of the central nervous system and therefore exists in the peripheral nervous system will repair damaged axons. • Radial
typically is diagnosed in the second or third decade of life. Normally, nerves are enclosed in myelin sheaths that help facilitate transmission of nerve impulses within the CNS and the peripheral nervous system throughout the body. In patients with MS, the myelin sheath is damaged and eventually degenerates, causing patches of scar tissue called plaques or lesions to occur anywhere randomly on the myelin sheath (Ruto, 2013). This results in impaired nerve conductivity, which interferes with message
sclerosis is a mystery disease, scientists are working to determine the exact cause and treatment. Multiple sclerosis is an autoimmune disease that involves the different areas of the central nervous system, the brain, and spinal cord. It damages the myelin sheath, the material that surrounds and protects the
in the myelin sheath that causes many problems for the nervous system. The major problem is caused when the enzyme aspartoacyle is not present. This missing enzyme causes a chemical imbalance that causes this defect in the myelin sheath. The myelin in the brain destructs which makes it a spongy tissue. This causes overall muscle weakening and slower movements, leading to severe mental retardation. A recent study has shown that the cells in the brain that are responsible for making myelin sheaths
the central nervous system to the sensory organs. Some of the neurons within the central nervous system are surrounded by a myelin sheath. Myelin insulates the axon and allows electrical impulses to travel faster throughout the body. Oligodendrocytes produce myelin in the central nervous system and can wrap myelin around several axons at a time. Some Schwann cells produce myelin in the peripheral nervous system. Unlike oligodendrocytes, Schwann cells can only wrap around one axon at a time.
an inherited disorder that causes progressive damage to the nerve cells in the brain. It is in the group of rare genetic disorders called Leukodystrophies. Leukodystrophies are characterized by the degeneration of myelin, which is the fatty covering that insulates nerve fibers. The myelin is necessary for rapid electrical signals between the neurons. I chose this disease because I had never heard of it and it seems to only affect a very small amount of people. Also it isn’t very common so I wanted
sclerosis. Multiple sclerosis (MS) is generally thought to be an autoimmune disease that attacks the myelin sheaths, or oligodendrocytes that cover nerve axons in the central nervous system (PubMed Health 2013). This immune response causes inflammation, which triggers immune cells to destroy axons “along any area of the brain, optic nerve, and spinal cord” (PubMed Health 2013). When the myelin sheath “is damaged, nerve signals slow down or stop” thus hindering the propagation of action potentials
Kayla was just an average 14 year old playing in a soccer tournament. She fell a couple of times, once on her tailbone and another on her neck ("Kayla Montgomery"). There was a tingling sensation running up and down her spine, and she lost feeling from the waist down ("Kayla Montgomery"). Shortly after her fifteenth birthday, she was diagnosed with Multiple Sclerosis, or MS for short ("Kayla Montgomery"). Her disease hasn’t progressed from the time she was diagnosed to now, so she is still able to
MSM is a dietary supplement that has become known as the "miracle supplement" because it has garnered a reputation for treating several illnesses and diseases. Presently, MSM is gaining popularity with people who are looking for the perfect supplement that has a wide variety of health benefits. It has been found, with very limited scientific research, that MSM serves as an important source of readily available dietary sulfur, which is known to be critical in maintaining the integrity and elasticity
Astrocytes are star-shaped glial cells found within the central nervous system, outnumbering neurons 7:5 in the human brain (Nedergaard et al., 2003). Following their initial discovery in the 19th century, astrocytes were originally viewed as passive support cells for neurons, providing a physical scaffold for neuronal organization (Nair et al., 2008). However, it is now recognized that astrocytes play a more active role in cerebral function, from ionic homeostasis and neurotransmitter recycling
Many people have never heard of Adrenoleukodystrophy it is a disease that affects every 1 in 20,000 people from all races (Moser, AB HW, and KK Frayer). It is a disease that if not treated properly can possibly kill the child due to difficulties. Adrenoleukodystrophy is passes down from parents to their children as an X-linked trait. Since ALD is X-linked trait it mostly affects male, women can also carry the trait but it will remain dormant. If a woman has ALD she will only display a milder form
The myelin sheath has its own specific and characteristic ultrastructure to help it carry out its function efficiently (Morell and Quarles, 1999). Myelin is a modified and extended version of the plasma membrane found in a spherical pattern wrapped around the axon of a neurone. Damage of the myelin sheath can lead to a condition called multiple sclerosis. Multiple sclerosis is a disorder which can result
Myelin protects and electrically insulates fibers and increases the transmission speed of nerve impulses. Myelin sheaths in PNS are formed by Schwann cells, which indent to receive an axon and then wrap themselves around it in a jellyroll fashion. In CNS, the oligodendrocytes form myelin sheaths. Unlike Schwann cells, oligodendrocytes have multiple flat processes that can coil around as many as 60 axons at a time. In PNS, myelin sheath gaps separate adjacent sections of an axon’s myelin sheath
spinal cord. MS attacks myelin, the fatty material that acts as a protective coating to the body's nerves. (1) The inflammation of the nerve tissues covering the nerves can affect any part of the nervous system and varies from person to person. (7) Normal nerve function decreases with the onset of MS because MS causes scars to form on the covering of the nerve. Multiple Sclerosis acquires this term because it literally means scars. (1,7) The covering of the nerve with myelin is very important so that
The process of memorization starts at birth with the development of cells and extends throughout the lifetime through the effects of life experiences and stimulants. Like the rest of the body, the brain is made up of cells. These brain cells are different, more specialized cells. (Sprenger 1). Two major brain cells are the neurons- the nerve cells- and the glial cells which work as the ‘glue’ of the neurons. At birth, the brain contains approximately 100 billion neurons. Although that number remains
spinal cord—otherwise known as the central nervous system (CNS). In people with MS, their immune system mistakenly attacks the protective covering of all neurons, which is called the myelin sheath. When the myelin sheath is damaged, it forms a type of scar tissue called sclerosis—giving the disease its name. Since the myelin sheath is damaged, nerve impulses that travel to and from the CNS (brain and spinal cord) become distorted or interrupted. This causes major communication issues between the brain
Guillain-Barre Syndrome is a disorder in the body’s immune system attacks a person nerves. The accurate cause of this syndrome is unknown, stomach flu and respiratory function is however caused by GBS that can cause an infectious illness. (Parry & Steinberg, 2007, pg. 24). Guillain-Barre syndrome is a uncommon disorder, it usually starts with a tingling and weakness starting in a persons feet of legs and slowly spreading to the upper body and arms. These symptoms occur after four weeks and
condition where the body’s immune system mistakenly attacks normal tissues. In Multiple Sclerosis, the patient’s own cells & antibodies attack the fatty myelin sheath that protects and insulates nerve fibres in the brain and spinal cord, the two components of the CNS. This ultimately causes damage to the nerve cells and without the insulation the myelin sheath provides, nerve communication is disrupted. Hence, Multiple Sclerosis is characterized by symptoms that reflect central nervous system involvement
the brain and spinal cord (Dangond). Within the central nervous system there are cells that are covered with a protective myelin. In people with MS, the myelin sheaths around the cells begin to deteriorate and the nerve fibers, also known as axons, which are normally protected by the myelin, end up being destroyed (Boroch). After a while scar tissue is replaced where the myelin breaks down, hence the name multiple sclerosis or many scars (Boroch).When the nerve fibers are destroyed they begin to lose
