oligodendrocyte

[ol′igōden′drəsīt]
Etymology: Gk, oligos + dendron, tree, kytos, cell
a type of neuroglial cell with dendritic projections that coil around axons of neural cells. The projections continue as myelin sheaths over the axons.

oligodendrocyte

(ol?i-go-den'tro-sit) [? + ? + kytos, cell]
A glial cell found most commonly in axon tracts; it myelinates axons in the central nervous system just as Schwann cells myelinate axons in the peripheral nervous system. Oligodendrocytes are neuroectodermal cells that originate from different precursors in the neural tube than astrocytes; later, stem cells in the subependymal layer can continue to generate new oligodendrocytes. Mature oligodendrocytes wrap neighboring axons in myelin, and some oligodendrocytes can simultaneously wrap many axons. However, not all oligodendrocytes myelinate axons.

oligodendrocyte

A connective cell of the central nervous system (glial cell) that participates in the formation of the myelin sheaths of nerve cell axons.
