Cytoskeletal Structures: Drag The Labels Onto The Diagram To Identify Cytoskeletal Structures
The cytoskeleton is a dynamic network of protein filaments and tubules that provides structural support and organization to eukaryotic cells. It plays a crucial role in various cellular processes, including cell shape maintenance, cell division, intracellular transport, and cell signaling.
There are three main types of cytoskeletal structures: microtubules, microfilaments, and intermediate filaments.
Microtubules
Microtubules are long, hollow, cylindrical structures composed of tubulin proteins. They are the thickest of the cytoskeletal structures, with a diameter of about 25 nm. Microtubules are responsible for maintaining cell shape, providing structural support, and facilitating intracellular transport. They also play a critical role in cell division, forming the mitotic spindle that separates chromosomes during cell division.
- Examples:Spindle fibers, cilia, and flagella
- Function:Cell shape maintenance, intracellular transport, cell division
Microfilaments
Microfilaments are thin, solid, filamentous structures composed of actin proteins. They are the smallest of the cytoskeletal structures, with a diameter of about 7 nm. Microfilaments are involved in cell shape changes, cell movement, and muscle contraction. They also play a role in cell division, forming the contractile ring that pinches the cell in two during cytokinesis.
- Examples:Actin filaments, stress fibers
- Function:Cell shape changes, cell movement, muscle contraction, cell division
Intermediate Filaments, Drag the labels onto the diagram to identify cytoskeletal structures
Intermediate filaments are intermediate in size between microtubules and microfilaments, with a diameter of about 10 nm. They are composed of various proteins, including keratin, vimentin, and desmin. Intermediate filaments are responsible for providing mechanical strength and stability to cells.
They also play a role in cell shape maintenance and cell-cell adhesion.
- Examples:Keratin filaments, vimentin filaments
- Function:Cell shape maintenance, cell-cell adhesion, mechanical strength
