Myelin

Myelin is a fatty sheath that coats nerve cells. It consists of about 70% lipids. In the central nervous system, it is made of oligodendrocytes. One oligodendrocyte can myelinate many axons. In the peripheral nervous system, myelin is made of a Schwann cell. One Schwann cell can myelinate only one axon. Oligodendrocytes and Schwann cells form myelin by wrapping around the axon. The myelin sheath is a good insulator. It also creates low capacitance. This means that fewer ions are needed to charge

A Look at Myelin and Myelin-Related Disorders Myelin is the protective sheath around axons in the nervous system, and is often referred to as 'white matter.' It acts as an insulator to the electrical signal that is conducted down the axon as a neuron fires, and can well be compared to the insulation around an electrical wire. The myelin sheath contains a variety of fatty substances (lipids), and contains at least ten distinct chemicals (2). . From what is known, axons are not fully myelinated

The Myelin Sheath: Essential for Rapid Saltatory Conduction The synthesis and maintenance of the myelin sheath is critical for normal neural function because myelination is responsible for the saltatory conduction of action potentials that significantly increases the conduction velocity of electrical signals (Bartzokis, 2004). The conduction velocity of propagation is important because it controls the flow of information necessary for vital cognitive functions. The axon of a nerve cell is insulated

central nervous system that has the potential to cause significant disability in those affected through the body's immune system attacking and destroying the myelin sheaths surrounding the axons. Myelin is rich in lipids and proteins that form layers around the nerve fibers and acts as insulation and protection. This damage to the myelin in the CNS, and to the actual nerve fibers, has the potential to block the transmission of nerve signals between the brain and spinal cord and also other parts

The myelin sheath is where the nerve axons serve as an electrical insulator that speeds up nerve impulses to muscles and other effectors. The damage of the myelin sheath is caused by inflammation of the brain, and may have significant damages to other areas as well. Damaged areas undergo scarring or plaques. Plaques may be found in different areas of the brain, which include: optic nerves, spinal cord, cerebellum, brainstem, and cerebral area of the brain. Researchers have found evidence of damage

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. MS is

English Abstract Multiple sclerosis (MS) is a chronic inflammatory, neurodegenerative disease that affects more than 40,000 individuals in Egypt alone and 2.5 million people worldwide. MS is also categorized as an autoimmune disease in which the immune system instigates an immune response upon encountering the specific myelin antigen and therefore initiating a constant degradation of the myelin sheath. The frequent loss of the myelin leads to irreversible

As described in the book “myelin is the insulation that wraps (these) nerve fibers and increases signal, speed, strength, timing, and accuracy of nerve fibers” (pg. 1). 32.

The article goes into depth about the different experiments that have gone on. For example, McKenzie et al. had done an experiment with adult mice to determine if there was a difference in mice that grew new oligodendrocytes. The article also went into great detail about different disorders caused by damaged or malfunctioned myelin. Myelin

cell membrane. In some areas of the nervous system that require faster communication, the axons will contain insulation, known as the Myelin Sheath. (Myelin sheath)-The Myelin Sheath is made up of a material called myelin, which is produced by special cells known as Schwann cells. (Schwann cells)-Schwann cells are in the Peripheral nervous system that form the Myelin Sheath around an axon. (Axon Terminal)-Finally, the axon terminal
