Oligodendrocytes are a type of glial cell, non-neuronal cells in the central nervous system.They arise during development from oligodendrocyte precursor cells (OPCs), [8] which can be identified by their expression of a number of antigens, including the ganglioside GD3, [9] [10] [11] the NG2 chondroitin sulfate proteoglycan, and the platelet-derived growth factor-alpha receptor subunit (PDGF ...
Cell bodies of neurons are in yellow (Their axons are surrounded by myelin, produced by oligodendrocytes). Cellular extensions also known as cytoplasmic protrusions and cytoplasmic processes are those structures that project from different cells , in the body, or in other organisms.
Oligodendrocytes are cells that coat axons in the CNS with their cell membrane, forming a specialized membrane differentiation called myelin, producing the myelin sheath. The myelin sheath provides insulation to the axon that allows electrical signals to propagate more efficiently.
In the central nervous system, axons are myelinated by oligodendrocytes, thus lack neurilemma. The myelin sheaths of oligodendrocytes do not have neurilemma because excess cytoplasm is directed centrally toward the oligodendrocyte cell body. Neurilemma serves a protective function for peripheral nerve fibers.
The Delaware judge considering whether a vote by Tesla shareholders reinstated Elon Musk's $56 billion pay package which the court had voided will try to issue a ruling this year, according to the ...
While it has been suggested that radial glia most likely give rise to oligodendrocytes, through the generation of oligodendrocyte progenitor cells (OPCs), and OPCs can be generated from radial glial cells in vitro, more evidence is yet needed to conclude whether this process also occurs in the developing brain.
