The cytoskeleton is a network of protein filaments and tubules that provides structure, shape, and movement to the cell. It plays crucial roles in intracellular transport and cellular division.
5 Must Know Facts For Your Next Test
The cytoskeleton consists of three main components: microfilaments, intermediate filaments, and microtubules.
Microfilaments are composed of actin and are involved in cell movement and muscle contraction.
Intermediate filaments provide mechanical support for the cell and help maintain its shape.
Microtubules are made of tubulin and are essential for cell division, forming the mitotic spindle.
The cytoskeleton is dynamic, constantly reorganizing itself in response to cellular needs.
