osteoid
Definition
Adjective:
- Resembling bone: "osteoid" describes something that has the appearance or characteristics of bone tissue.
- Related to bone formation: In medical contexts, "osteoid" refers to the organic, unmineralized matrix of bone that is produced by osteoblasts before calcium salts are deposited.
Noun (rare, technical):
- Bone-like substance: "osteoid" can also refer to a substance or tissue that is similar to bone in structure or composition, particularly the uncalcified precursor of bone.
Usage Examples
Adjective:
- The pathologist noted an osteoid matrix in the tissue sample. (The tissue had a bone-like composition.)
- Osteoid tissue is essential for the formation of new bone. (The unmineralized bone matrix is crucial for bone growth.)
Noun:

Advanced Usage
"Osteoid osteoma": a benign bone tumor consisting of osteoid tissue surrounded by reactive bone.

Variants and Related Words

- Osteogenesis (n): the formation of bone, which involves the production of osteoid.
Synonyms

- Osseous: relating to or consisting of bone.
- Calcifiable: capable of being turned into bone through mineralization.
Related Idioms
