What does medullated mean?
Medullated is a formal, specialized adjective meaning that something has, or resembles, a medulla—the soft or pithlike inner core of a plant or the internal tissue of an organ. A familiar technical use is in textile and hair science, where medullated fibres are fibres that contain a central core or medulla. Such fibres differ from fibres without a medulla and can differ in coarseness, strength, and crimp; the terminology is therefore used when fibre structure is being examined. In anatomy and botany, medullated describes tissue or material possessing a medullary core. The word is comparatively uncommon outside specialist writing and is more explicit than the broader adjective medullary. Medullated is typically used attributively in expressions such as medullated fibres and medullated wool, and it has no widely established regional distinction between British and American English. Its usefulness lies in naming a specific structural feature rather than merely identifying the tissue or material involved.
adjectiveHaving or resembling a medulla, especially a fibre containing a soft or pithlike central core.
- Containing a medulla or central core, especially a fibre with a soft inner core.
- Resembling a medulla in appearance or structure.

"The pathologist noted medullated tissue in the specimen."
A medullated fibre carries its name from its centre: its medulla is the core running through the shaft.

Where does medullated come from?
The English adjective belongs to the Latin medulla family. Latin medulla meant “marrow,” “pith,” or “inner core,” and it was borrowed into English as medulla during the late Middle English period. English subsequently developed medullary and medullated from the same stem, with medullated using the medullat- form and the ending -ed to express the presence of a medulla. Related medical terms such as medulloblast and medullitis preserve the same Latin root.
How medullated is actually used
Rare, formal, and specialist in register, occurring chiefly in anatomy, botany, and textile or fibre analysis. It is standard in both British and American English, although surrounding vocabulary may use the respective spellings fibre or fiber.
