Cytoskeleton

Definition

The cytoskeleton is a network of fibers in cells that helps maintain their shape, offers support, and facilitates movement.

Scientific / Technical Definition

The cytoskeleton is a complex, dynamic network of interlinking protein filaments and tubules that extends throughout the cytoplasm of a cell. In animals, it is composed of three main components: microfilaments, intermediate filaments, and microtubules. Each component plays a crucial role in cell stability, intracellular transport, cellular division, and muscle contraction.

Benefits

• Maintains cellular structure and shape.
• Assists in cellular movement and transport of materials within cells.
• Plays a vital role in muscle contraction and therefore muscle growth.
• Contributes to cell division and replication processes.

Examples

• In terms of practical examples, components of the cytoskeleton like actin and myosin are crucial for muscle function.

Additional Information

• Importance: The cytoskeleton is important for the mechanical support, cell shape maintenance, and enabling cellular motion, including muscle movement crucial for physical development and repair.
