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. |
