Oligodendrocyte

Oligodendrocyte

Oligodendrocytes (from Greek, signifying 'cells with a couple of branches'), or oligodendroglia, are a sort of neuroglia found by Pío del Río Hortega. Their principle capacities are to offer help and protection to axons in the focal sensory system of a few vertebrates, equal to the capacity performed by Schwann cells in the fringe sensory system. Oligodendrocytes do this by making the myelin sheath, which is 80% lipid and 20% protein. A solitary oligodendrocyte can stretch out its procedures to 50 axons, wrapping roughly 1 μm of myelin sheath around every axon; Schwann cells, then again, can fold over just a single axon. Every oligodendrocyte shapes one section of myelin for a few contiguous axons.

Oligodendrocytes are discovered just in the focal sensory system, which contains the mind and spinal rope. These cells were initially thought to have been delivered in the ventral neural cylinder; in any case, explore now demonstrates oligodendrocytes begin from the ventral ventricular zone of the embryonic spinal string and perhaps have a few focuses in the forebrain. They are the last cell type to be created in the CNS.
