Get Myelin Sheath Brain Damage UK. The myelin sheath wraps around the fibers that are the long threadlike part of a nerve cell. The myelin sheath is a protective coating around nerves.
Multiple Sclerosis Microglia Cells Damage The Myelin ... from media.istockphoto.com However, if the sheath is severely damaged, the underlying nerve fiber can die. Such disorders finally lead to the nerve cells there are in fact fewer of these proteins in oligondendrocytes in parts of the brain affected by ms. The myelin sheath is a protective covering that surrounds fibres called axons, the long thin these unprotected nerves are then less able to conduct electrical impulses from the brain to other parts of the body determining the extent of damage to the myelin sheath may be key to predicting how severe.
In a myelinated axon, the myelin sheath prevents the local current (small black arrows) from flowing across the membrane.
Special cells called oligodendrocytes or schwann cells create and store large amounts of myelin. Damage to myelin sheaths or to the cells from which they are produced leads to serious disorders such as ms. Such disorders finally lead to the nerve cells there are in fact fewer of these proteins in oligondendrocytes in parts of the brain affected by ms. The myelin sheath is a protective coating around nerves.
