osseous tissue
Học thuậtThân thiện
Definition
Noun The dense, hard, and porous connective tissue that forms the rigid part of bones; bone tissue. It is a specialized form of connective tissue consisting of cells (osteocytes) embedded in a hard, calcified matrix of collagen fibers and mineral salts, primarily calcium phosphate.
Usage
"Osseous tissue" is a formal, scientific term used in anatomy, biology, and medicine to refer specifically to the structural material of bones. It describes the living, mineralized tissue itself, as opposed to the entire bone organ (which includes marrow, blood vessels, and other tissues).
Examples
- The X-ray revealed a fracture that completely disrupted the osseous tissue.
- Osteoporosis is a disease characterized by a decrease in the density and strength of osseous tissue.
- The biopsy examined the health of the osseous tissue for signs of abnormality.
- The primary function of osseous tissue is to provide support and protection for the body.
Advanced Usage
- Histological Context: In histology (the study of tissues), osseous tissue is classified into two main types based on its porosity and organization: compact (cortical) bone and spongy (cancellous or trabecular) bone. Both types are forms of osseous tissue.
- Pathological Context: The term is used to specify the tissue involved in diseases (e.g., "infection of the osseous tissue") or surgical procedures (e.g., "graft of autologous osseous tissue").
Variants and Related Words
- Bone: The common, non-technical term for the organ or the hard substance. While "bone" often refers to the whole structure, it can be used informally to mean osseous tissue (e.g., "bone density").
- Bone Tissue: A direct synonym for osseous tissue, slightly less formal but still technical.
- Osteoid: The unmineralized, organic portion of the bone matrix (mainly collagen) secreted by osteoblasts, which later becomes mineralized to form mature osseous tissue.
- Osseous (adjective): Of, relating to, or consisting of bone or bone tissue. (e.g., "osseous structures," "osseous growth").
Synonyms
- Bone tissue
- Bony tissue
Related Phrases / Compounds
- Osseous integration: The direct structural and functional connection between living bone (osseous tissue) and the surface of a load-bearing artificial implant.
- Osseous labyrinth: The bony canals of the inner ear, which are hollowed out of the temporal bone and house the membranous labyrinth.
Noun
- the porous calcified substance from which bones are made
