3. Source of Myelin Sheath: The myelin sheath is formed by specific types of cells. In the peripheral nervous system (PNS), the myelin sheath is produced by Schwann cells. In contrast, in the central nervous system (CNS), oligodendrocytes are responsible for myelin formation. 4. Evaluating ...
The myelin sheath is an essential, multilayered membrane structure that insulates axons, enabling the rapid transmission of nerve impulses. The tetraspan myelin proteolipid protein (PLP) is the most abundant protein of compact myelin in the central nervous system (CNS). The integral membrane protein...
The myelin sheath is formed by oligodendrocytes in the central nervous system (CNS) and by Schwann cells in the peripheral nervous system (PNS). The myelin sheath presents a highly organized structure and expands both radially and longitudinally, but in a different way and with a different ...
systems. The sheath is formed by the wrapping of multiple layers of the cellular membrane (mainly lipoprotein) of the myelin-producing cells around the axon. In the central nervous system (CNS) these cells are theoligodendrocytes, and in the peripheral nervous system (PNS) these cells are...
Glycoproteins are well established as cell-surface components and appear to participate in specific cell-cell interactions. Myelin is formed as an extension of the plasma membrane of the oligodendrocyte in the central nervous system (CNS) and the Schwann cell in the peripheral nervous system (PNS)...
Answer to: Myelin ... a. is a type of neurotransmitter b. disrupts neurological activity c. is produced by the action potential ...
Myelin is formed as an extension and modification of the surface membrane of the oligodendrocyte in the central nervous system (CNS) and the Schwann cell in the peripheral nervous system (PNS). The extended plasma membranes are wrapped around the axons in a spiral fashion, leading to a structur...
Fill in the blank: A fascicle of axons is surrounded by a connective tissue sheath called the ___. Which cell is wrapped around nerve fibers in the PNS? What is the pathway of an axon of a somatic motor neuron? Within the peripheral nervous system, myelin is formed by the ___. A ...
Myelin is a lipid-protein membrane that is spirally wound in a multilamellar sheath that is formed by a high lipid content and proteins. The myelin sheath is related to motor, sensory, and cognitive development and is the most recent evolution of the nervous system among the human species (...
CNS myelin is a spiral structure similar to PNS myelin; it has an inner mesaxon and an outer mesaxon that ends in a loop, or tongue, of glial cytoplasm (Figure 10-3). Unlike peripheral nerve, where the sheath is surrounded by Schwann cell cytoplasm on the inside and outside, the ...
