This chapter presents an overview of myelin structure and function and its communication with axons it ensheaths. The chapter also describes the current understanding of axoglial communications and the role of glial cells in myelin disorders.Joseph Hanig...
The structure of the myelin sheath comes mostly from lipids, with some proteins mixed in as well.What are Schwann Cells and Oligodendrocytes? What is the Function of the Myelin Sheath? Why is the Myelin Sheath Important? What Happens in the Gaps Between Schwann Cells? How Does Myelination ...
The myelin sheath is a stable and resistant structure. During early stages of the myelination process (i.e., synthesis and deposition of the myelin); however, it is vulnerable to external influences. Oligodendrocyte maturation requires intrinsic and extrinsic factors, such as growth factors, ...
Observing the structure and regeneration of the myelin sheath in peripheral nerves following injury and during repair would help in understanding the pathogenesis and treatment of neurological diseases caused by an abnormal myelin sheath. In the present study, transmission electron microscopy, immunofluoresce...
entity, functional studies often discriminate between roles strictly related to the cells themselves and those specifically associated with myelin per se. The myelin sheath is a highly specialized multilamellar membrane that wraps axons. Central myelin is structured by an ensemble of compact ...
Sheath laminae end against the axonal membrane, leaving the naked axon exposed to the basal lamina (bl). Scale bar, 0.1 μm. Full size image Species lacking the myelin-like sheaths belong to two superfamilies, the Arietelloidea and Centropagoidea. Although abundant, they are restricted in ...
Identify the cranial nerve from its embryonic origin and the type of innervation that it carries: Ventral root; general sensory only Neurotransmitters cross the: a. dendritic membrane b. synapse c. myelin sheath Which of the following is NOT a function of neurotrophins? (a) Ma...
sheath,case- an enveloping structure or covering enclosing an animal or plant organ or part axolemma- outer membrane covering an axon medullated nerve fiber,myelinated nerve fiber- a nerve fiber encased in a sheath of myelin nodes of Ranvier,Ranvier's nodes- small gaps in the myelin sheath ...

Oligodendrocytes extend numerous cellular processes that wrap multiple times around axons to generate lipid-rich myelin sheaths. Myelin biogenesis requires an enormously productive biosynthetic machinery for generating and delivering these large amounts
