hyaloplasm
Học thuậtThân thiện
Definition
Noun The clear, fluid-like, and non-granular (lacking visible particles or granules) portion of the cytoplasm within a cell. It is the soluble, liquid component in which organelles and other cell structures are suspended.
Usage
Hyaloplasm is a specialized biological term used primarily in cell biology and cytology to describe the specific, transparent ground substance of the cytoplasm. * The hyaloplasm provides a medium for the transport of molecules and the movement of organelles within the cell. * Under a microscope, the hyaloplasm appears as a clear area surrounding the more visible organelles.
Examples
- Noun:
- The movement of vesicles through the hyaloplasm is essential for cellular function.
- In many cells, the hyaloplasm constitutes the largest volume of the cytoplasm.
- The study focused on the viscosity and composition of the hyaloplasm.
Advanced Usage
- The term is often used in contrast to the granular components of the cytoplasm, such as ribosomes or storage granules. It is synonymous with the term cytosol, though some scientific contexts may make a subtle distinction, with "cytosol" sometimes referring specifically to the hyaloplasm minus the cytoskeleton.
Variants and Related Words
- Cytosol (noun): Often used interchangeably with hyaloplasm; the liquid matrix of the cytoplasm.
- Cytoplasm (noun): The entire contents of the cell within the cell membrane, excluding the nucleus. The hyaloplasm is a component of the cytoplasm.
- Ground substance (noun): A general term for the amorphous, fluid matrix in biological tissues; in cells, it refers to the hyaloplasm.
Synonyms
- Cytosol
- Intracellular fluid (in a specific context)
- Cytoplasmic matrix
Antonyms
- Organelle (a membrane-bound structure within the cytoplasm, suspended in the hyaloplasm).
- Granule (a small particle within the cytoplasm).
Noun
- the clear nongranular portion of the cytoplasm of a cell
