| Name: | oligodendrocyte |
|---|---|
| Synonyms: | oligodendroglia |
| Definition: | A class of large neuroglial (macroglial) cells in the central nervous system. Form the insulating myelin sheath of axons in the central nervous system. |

| Name: | myelin sheath |
|---|---|
| Synonyms: | astrocyte sheath, oligodendrocyte myelin sheath, Schwann cell myelin sheath |
| Definition: | An electrically insulating fatty layer that surrounds the axons of many neurons. It is an outgrowth of glial cells: Schwann cells supply the myelin for peripheral neurons while oligodendrocytes supply it to those of the central nervous system. |
