--Multiple Sclerosis is causes the demyelination of axons in the spinal cord and brain. This is a result of loss of oligodendrocytes and scarring of white matter in the nervous system. Also, demyelination in MS is inflammation caused by an autoimmune response. The inflammation prevents proper recovery and repair of axonal myelination.…
Myelin visited my office yesterday complaining of numbness in his right leg and face. He has also been experiencing muscle weakness and mild depression. I noticed a delay in his visual response in both eyes. I have referred Myelin to your facility because of possible multiple sclerosis, and I am requesting an MRI of the brain and spine. Please fax the results to me as soon as possible.…
Multiple sclerosis does affect the brain and the spinal cord. The myelin sheath is damaged when a person has multiple sclerosis (“Emedicinehealth”, 2012). A person that has multiple sclerosis will have nerve damage that is caused by inflammation in the brain, optic nerve, or spinal cord (“Emedicinehealth”, 2012). There are several structure and functions that can be…
When a person has multiple sclerosis, their own immune system attacks its tissue ("Mayo Clinic", 2013). The patients name is Myelin, which I guess has some significance since a fatty substance that coats nerves known as myelin is destroyed by the disease("Medical News", 2013) . This an electrically insulating material that surrounds the axon of a neuron; it is necessary for the proper function of the nervous system ("Medical News", 2013). When myelin is destroyed, it affects the entire nervous system causing important messages to become slow or blocked entirely ("Medical News", 2013). So in a patient with MS , this would cause them to experience muscle spasms or complete lack of…
It was 1868 when Dr. Jean Charcot discovered hardening of the plaques during an autopsy he was performing. He called it “Sclerosis in plaques,” also known as Multiple Sclerosis and today that affects more than 2.1 million people worldwide. MS is a chronic autoimmune disorder caused by the destruction of the myelin sheath that covers nerve fibers in the CNS. Myelin is the insulator of nerve conduction and it allows the signals to travel at fast speeds. During MS, demyelination occurs causing the nerves to fire at a slower rate than usual, making them fatigue more quickly. People with this disorder often have a variety of symptoms including problems with vision, strength, balance, coordination and sensation. Most people start developing symptoms between the ages of 20-40 with a higher occurrence happening in woman over men.…
If the myelin sheathing on neurons is absent or removed in a given individual, he or she will exhibit difficulties in speaking, vision, and balance because without myelin the…
The first step would be the stimulation whether it be air noises, water noises, music or someone coughing. The sound then travel to the outer ear where it is the reflected into the middle ear where it is amplified into the inner ear. The sound is then transferred through the viscous fluid in the cochlea. Inside the cochlea are tubes that are filled with fluid and hair cells. The hair cells are moved by the sound waves and become receptors for the primary auditory cortex. The cortex then processes the sounds into an interpretation. (University of Phoenix,…
Multiple Sclerosis (MS), a neurological condition, affects around 100,000 people in the UK and is most common is people aged 20-40 years old. MS affects the nerves in your brain and spinal cord causing problems with muscle control, vision and balance, sometimes even your memory, as well as your moods and emotions. It is when your immune system mistakes myelin (the coating around nerve fibres) as a foreign body therefore begins to attack it. However, myelin is a fatty substance that protects nerve fibres in the central nervous system, helping to send messages quickly and smoothly between the brain and the rest of the body. So when…
~Multiple sclerosis (MS) and Amyotrophic lateral sclerosis (ALS) both harm the white matter of the brain and cut the ties that allow the neurons to communicate with one another…
Amyotrophic Lateral Sclerosis ( Greek origin "A" means know, "Myo" refers to muscle, "Trophic" means nourishment ["No muscle nourishment"] with abbreviation of ALS) is a disease that effects the nervous and muscular system of the body. It was first studied in 1869 by Jean- Martin Charcot who was a French neurologist. In 1939 it gained international and national attention thanks to a man named Lou Gehrig. Gehrig was a baseball player for the New Year Yankees who ended up having to retire for the sport he loved because of his diagnosis of ALS, therefore Amyotrophic Lateral Sclerosis got its more common name Lou Gehrig's Disease. (ALS Association, 2016) Causes for ALS is still under investigation. Five…
Amyotrophic Lateral Sclerosis, also called ALS or Lou Gehrig's disease, is a genetic disease that affects the nerve cells that control muscle movement. ALS is a unique disease by the symptoms it causes when it is just beginning, the way it effects the people who have it, the people who are effected by it, and the way it is passed down from generation to generation in families.…

Inside our brain, there is this system called the human nervous system. There are two types of nervous systems: the peripheral and central nervous systems. The peripheral nervous system includes the nerves connecting the central nervous system to the rest of the body. It has two subdivisions: somatic nervous system and autonomic nervous system. Somatic nervous system controls skeletal muscles and interacts with the external environment. An example is walking through a park. You are using your motor nerves, which relay messages from the central nervous system, to all the skeletal muscles of your body. The autonomic nervous system regulates the body’s internal environment, which consists of organs, glands, and blood vessels. An example is breathing.…
Multiple Sclerosis is a “chronic inflammatory, demyelinating disease of the central nervous system” (Susan B. O’Sullivan, Physical Rehabilitation, p. 776). Multiple Sclerosis is a “disease where your body attacks itself, specifically the fatty coating called the myelin sheath on nerves in the brain, spinal cord, and eye area” (2016 EMD Serono,…
Multiple Sclerosis (MS) is the most common disabling neurological disease in young adults between 20 and 40 years of age. It is an autoimmune disease, meaning that it results from the body's immune system attacking its own cells. In this case, the immune system attacks myelin, the substance that coats nerve fibres, causing inflammation and damage to…
