oligodendrocyte

Examples of oligodendrocyte in the following topics:

• Glia

  • Oligodendrocytes form myelin sheaths around axons in the CNS .
  • One axon can be myelinated by several oligodendrocytes; one oligodendrocyte can provide myelin for multiple neurons.
  • Glial cells of the (a) central nervous system include oligodendrocytes, astrocytes, ependymal cells, and microglial cells.
  • Oligodendrocytes form the myelin sheath around axons.
  • (a) Astrocytes and (b) oligodendrocytes are glial cells of the central nervous system.

• Neuroglia of the Central Nervous System

  • Neuroglia in the CNS include astrocytes, microglial cells, ependymal cells and oligodendrocytes.
  • Oligodendrocytes are cells that have fewer processes compared to astrocytes.
  • Oligodendrocytes form the electrical insulation around the axons of CNS nerve cells.

• Types of Nervous Tissue

  • Neuroglia in the CNS include astrocytes, microglial cells, ependymal cells and oligodendrocytes.
  • Oligodendrocytes line up along the nerves and produce an insulating cover called myelin sheath.
  • Their function is similar to oligodendrocytes.

• Neuroglia of the Peripheral Nervous System

  • Functionally, the schwann cells are similar to oligodendrocytes of the CNS.

• Optic (II) Nerve

  • As a consequence, the fibers are covered with myelin produced by oligodendrocytes, rather than Schwann cells that are found in the peripheral nervous system.

• Regeneration of Nerve Fibers

  • The hostile, non-permissible growth environment is, in part, created by the migration of myelin-associated inhibitors, astrocytes, oligodendrocytes, oligodendrocyte precursors, and microglia.

• Muscle Tissues and Nervous Tissues

  • Astrocytes regulate the chemical environment of the nerve cell, while oligodendrocytes insulate the axon so the electrical nerve impulse is transferred more efficiently.
  • Also shown are two types of glial cells: astrocytes to regulate the chemical environment of the nerve cell, and oligodendrocytes to insulate the axon so the electrical nerve impulse is transferred more efficiently.

• Brain Tumors

  • Within the brain itself, the involved cells may be neurons or glial cells (which include astrocytes, oligodendrocytes, and ependymal cells).

• Introducing the Neuron

  • In the central nervous system, the glial cells that form the myelin sheath are called oligodendrocytes; in the peripheral nervous system, they are called Schwann cells.
  • This neuron diagram also shows the oligodendrocyte, myelin sheath, and nodes of Ranvier.
