What is the adjective form of bone marrow?

• A. Medullary
• B. Myeloid
• C. Osseous
• D. Hematopoietic

Answer: (A)

Medullary is the adjective that directly describes bone marrow. It comes from medulla, meaning marrow or the inner part, and is used in terms like the medullary cavity of a bone, which is the chamber that houses the marrow. While myeloid also relates to bone marrow in a broader hematology sense (referring to marrow-derived cells), it is more about cell lineages. Osseous means bone tissue itself, not the marrow, and hematopoietic refers to the formation of blood cells rather than describing the marrow itself. So medullary is the best fit for the adjective form of bone marrow.
