taste cell
Definition
Noun: A specialized sensory receptor cell located within a taste bud on the tongue and other parts of the oral cavity. Its primary function is to detect chemical stimuli (tastants) in food and drink, initiating the process of taste perception by activating nerve fibers connected to the brain.
Usage
A "taste cell" is a biological term used to describe a specific type of cell. It is typically used in scientific, medical, and educational contexts. - Each taste bud contains numerous taste cells. - The taste cell converts a chemical signal into an electrical nerve impulse.
Examples
- When you eat something sweet, a sugar molecule binds to a receptor on the surface of a taste cell.
- Damage to the taste cells can lead to a diminished sense of taste.
- Researchers are studying how taste cells differentiate between bitter and salty compounds.
Advanced Usage
- Taste cell turnover: Refers to the continuous process by which old taste cells die and are replaced by new ones, typically every 10 to 14 days.
- The rapid taste cell turnover ensures our sense of taste remains sensitive.
Variants and Related Words
- Gustatory cell: A direct synonym for "taste cell."
- Taste bud: The onion-shaped structure embedded in the tongue's epithelium that houses clusters of taste cells.
- Taste receptor: Often used interchangeably with "taste cell," though it can more specifically refer to the protein molecules on the cell's surface that bind to tastants.
Synonyms
- Gustatory cell
Related Terms and Phrases
- Taste pore: The small opening on the surface of a taste bud through which chemicals enter to contact the taste cells.
- Neurotransmitter release: The process by which an activated taste cell releases chemicals to stimulate the connected sensory nerve fiber.
Noun
-
an epithelial cell in a taste bud that activates sensory fibers of the facial nerve or the glossopharyngeal nerve or the vagus nerve
