- The contractile elements of the cytoskeleton include123:
- Microfilaments: These are part of muscle cells and allow for cell contraction, along with myosin.
- Intermediate filaments: Provide intracellular structural support and organization.
- Microtubules: Facilitate cytoplasmic streaming, organelle and cellular motility, transport of materials, and chromosomal movement during cell division.
