COMMON TYPES OF NEURO DISEASES - PART 3 - DEMYELINATING DISEASES

Demyelinating diseases are uncommon conditions in which the myelin sheath is attacked, resulting in neurodegeneration and eventual disability. The myelin sheath surrounds axons in the brain and peripheral nervous system. Axons are nerve cells that extend neurons. While neurons coordinate sensory and motor information in the brain, the axons deliver that information to where it needs to go; either between neurons or outside the brain to organs and tissues within the body.<br>More Info : https://myacare.com/en/mya-blog/common-types-of-neuro-diseases-part-3-demyelinating-diseases

  1. COMMON TYPES OF NEURO DISEASES - PART 3 - DEMYELINATING DISEASES

  2. In continuation on our series on Neurological Disease, here is the next segment on Demyelinating Diseases. Demyelinating diseases are uncommon conditions in which the myelin sheath is attacked, resulting in neurodegeneration and eventual disability. The myelin sheath surrounds axons in the brain and peripheral nervous system. Axons are nerve cells that extend neurons. While neurons coordinate sensory and motor information in the brain, the axons deliver that information to where it needs to go; either between neurons or outside the brain to organs and tissues within the body. The myelin sheath is a very important part of axonal function as it coordinates optimal electrical conductance. It ensures that neuro-impulses are transmitted at such rapid speeds that our perceptions and movements appear instantaneous. Myelin conductance is known as saltatory conduction and is a lot more efficient than normal neuronal transmission. The myelin sheath also acts as an insulator for the large amounts of electrical energy that nerves transmit; making sure nothing is lost in the process. Some demyelinating diseases attack the peripheral nervous system while others attack the central nervous system. The myelin sheath in either systems are not identical, being governed by distinctly unique neural cells. Oligodendrocytes (a type of nerve cell known as a glial cell) reside in the CNS and have many arm-like appendages that wrap around multiple axons within the brain. These wrappings form the myelin sheath and these cells constantly ensure that the myelin sheath remains salient. Schwann cells reside in the peripheral nervous system and are simpler than oligodendrocytes in structure, with individual cells forming a single wrapping of myelin across the axon segments they cover. https://myacare.com/en/mya-blog/common-types-of-neuro-diseases-part-3-demyelinating-dis eases Article Source :
