Cytoskeleton (Noun)
Meaning
A microscopic network of actin filaments and microtubules in the cytoplasm of many living cells that gives the cell shape and coherence.
Classification
Nouns denoting body parts.
Examples
- The cytoskeleton provides mechanical support, shape, and movement to cells, and is composed of three main components: microtubules, microfilaments, and intermediate filaments.
- Microtubules, which are part of the cytoskeleton, are involved in a variety of cellular processes, including mitosis, cytokinesis, and vesicle transport.
- In addition to its role in cell shape and division, the cytoskeleton also plays a key role in cell signaling and cell migration.
- Disruption of the cytoskeleton has been implicated in a variety of diseases, including cancer, muscular dystrophy, and neurodegenerative disorders.
- The dynamic reorganization of the cytoskeleton is crucial for many cellular processes, including cell migration, endocytosis, and exocytosis.
