The correct Answer is:C Each segment of myelin sheath is formed by one Schwann cell.Myelin sheath is present in the myelinated nerve fibres.It is made up of a substance of lipids, proteins and water called myelin and serves as an insulating layer, preventing loss of energy of the nerve ...
Myelin sheath is made up of phospholipids and is present around the View Solution Myelin sheath is present around the View Solution Doubtnut is No.1 Study App and Learning App with Instant Video Solutions for NCERT Class 6, Class 7, Class 8, Class 9, Class 10, Class 11 and Class 12, ...
The myelin sheath that is present on some types of nerves is composed largely of proteins and fats. Some diseases, like multiple sclerosis, destroy the myelin and cause scarring in the brain. Answer and Explanation: Learn more about this topic: ...
Multiple sclerosis (MS) is associated with breakdown of the myelin sheath that coats neurons in the central nervous system. The cause of MS is not known, although the pathogenesis involves destruction of myelin by the immune system. It was the aim of this study to examine the abundant myelin...
At present, mitochondria are considered the organelles responsible for the OXPHOS, but in the last years we have demonstrated that it can also occur outside the mitochondrion. Myelin sheath is able to conduct an aerobic metabolism, producing ATP that we have hypothesized is transferred to the ...
in contaminating membranes not related to myelin. The major myelin-associated glycoprotein is probably not present in compacted myelin, but immunocytochemical and subfractionation studies indicate that it is confined to the periaxonal and paranodal region of the myelin sheath. In experimental ...
The present chapter describes that aspect of our studies that is concerned with the mechanism of myelin sheath damage in inflammatory demyelinating diseases such as multiple sclerosis (MS) and Guillain-Barre syndrome (GBS). Our work has been largely conducted in vitro , and most of it has been...
Myelin is an insulating layer, also called a sheath, which is present around the nerves, even those in the central nervous system and spinal cord. This, in turn, is composed of proteins and fatty substances. Said sheath favors the conduction of electrical impulses which facilitates the transmiss...
α-/β-Dystroglycans (DG) located at the outmost layer of myelin sheath play a critical role in its formation and stability in the peripheral nerve system. The demyelination of nerve fibers is present in autoimmune neuritis, however, it is not known about the molecular mechanisms underlying this...
1B) Compact myelin forms the bulk of the myelin sheath. It is largely composed of lipids, mainly cholesterol and sphingolipids, including galactocerebroside and sulfatide [142]. Non-compact myelin is found in the paranodes and incisures. Because mutations in P0 (MPZ), PMP22 (PMP22), and...
