Note: This statement combines anatomy and/or ontology terms with phenotype quality terms to create a complete phenotype (EQ) statement. For detailed information on individual terms, click the hyperlinked term name.
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.
Ontology: Anatomy Ontology [ZFA:0009076]
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.

Definition: A quality of a single physical entity inhering in the bearer by virtue of the bearer's size or shape or structure.
