Cytoskeleton
Videos
The cytoskeleton is a complex, dynamic network of interlinking protein filaments present in the cytoplasm of all cells, including those of bacteria and archaea. In eukaryotes, it extends from the cell
The cytoskeleton consists of (a) microtubules, (b) microfilaments, and (c) intermediate filaments.

Protein filament
Videos
In biology, a protein filament is a long chain of protein monomers, such as those found in hair, muscle, or in flagella. Protein filaments form together to make the cytoskeleton of the cell. They are

This is a representation of a microfilament breakdown in a muscle fiber. It shows the different zones and disks within the sarcolemma of this muscle fiber.
This helps depict the role that microtubules play in cellular division. In this fluorescent image, the microtubules are highlighted green and can be seen helping to pull the cells apart.
