Study Notes
Cytoskeleton
- Comprises of three structural materials: actin filaments, intermediate filaments, and microtubules, which provide cell shape and structure.
Actin Filaments
- Critical components of the contractile apparatus.
- Involved in various cellular processes, including:
- Locomotion.
- Determining cell shape.
- Ability to move by amoeboid-like movements.
- Cell division.
- Muscle contraction.
Intermediate Filaments
- Primarily structural in function.
- Found in desmosomes and hemidesmosomes.
- Provide strength to cells.
Microtubules
- Radiate from the centrosome.
- Involved in various cellular processes, including:
- Intracellular transport of vesicles.
- Chromosome movement.
- Movement of cilia and flagella.
