odontoblast
Definition
Noun (Anatomy, Biology): - A specialized cell that forms dentin, the hard tissue beneath the enamel of a tooth. Odontoblasts are located along the outer surface of the dental pulp and produce dentin throughout life, especially in response to injury or decay.
Usage Examples
- (The cell produces dentin material.)
- (The cell reacts to injury.)
- (These cells are crucial for dental health.)
Advanced Usage
- "Odontoblast process": a long, thin extension of the odontoblast cell that extends into the dentin tubules, transmitting sensory signals.
- The odontoblast process helps detect temperature changes in the tooth. (The extension senses stimuli.)
- "Odontoblast differentiation": the process by which precursor cells become odontoblasts during tooth formation.
- Odontoblast differentiation is regulated by growth factors. (The cell specialization is controlled.)
Variants and Related Words
- Odontoblastic (adj): relating to or involving odontoblasts.
- The odontoblastic layer lines the pulp cavity. (The cell layer is present.)
- Odontoblast-like cells (n): cells that resemble odontoblasts, often used in research.
- Stem cells can be induced to form odontoblast-like cells in the lab. (Similar cells are produced artificially.)
Synonyms
- Dentin-forming cell: a cell that creates dentin (a descriptive synonym).
- Dentinoblast: a less common term for the same cell type.
Related Idioms
- None. "Odontoblast" is a specialized scientific term with no idiomatic usage.
Additional Information
- Etymology: Derived from Greek "odous" (tooth) + "blastos" (germ or bud), meaning "tooth bud cell."
- Context: This term is used primarily in dentistry, histology, and developmental biology.
