Definition
- Adjective:
- Having a porous, spongy, or lattice-like internal structure, typically referring to bone tissue. This structure consists of a network of trabeculae (small bony struts) that creates many small spaces, making the tissue lightweight yet strong.
Usage
- Descriptive Use: Used primarily in anatomical and medical contexts to describe the internal architecture of certain bones.
- Typical Contexts: Appears in discussions of bone biology, orthopedics, dentistry, and comparative anatomy.
Examples
- Adjective:
- The interior of the vertebra is composed of cancellous bone, which is less dense than the outer cortical bone.
- The biopsy revealed healthy cancellous tissue with a normal trabecular pattern.
- This species has remarkably lightweight bones due to an extensive cancellous structure.
Advanced Usage
- "Cancellous bone": The standard and most common compound term. It refers specifically to the spongy, porous bone tissue found at the ends of long bones and inside vertebrae, contrasting with dense "cortical" or "compact" bone.
- The implant was designed to integrate well with the patient's existing cancellous bone.
- "Cancellous structure": Used to describe the porous, lattice-like architecture itself, not limited to bone.
- The coral's cancellous structure provides habitat for many small organisms.
