Cytoskeleton - Coggle Diagram
Cytoskeleton
Intermediate filaments
Composed of
Keratin
Vimentin
Functions:
2.Tension bearing
3.Maintenance of cell shape
1.Anchoring of the nucleus and other organelles
4.No role in cell movement
Microfilaments
Composed of: Actin
Functions:
3.Cell contractility
4.Cytokinesis
2.Cell motility
1.Changes in cell shape
5.Mechanical stability
6.Amoeboid movement (pseudopods)
Microtubules
Functions:
1.Cell motility
2.Cell shape and structure
3.Intracellular transport of organelles (secretory vesicles)
4.Movement of cilia and flagella
Cilia
Moves fluids along cell surface
20 Times shorter than flagella
Short and Many
Found In:
1.Lining of the trachea, sweep mucus and dirt out of the lungs
Lining of the fallopian tube, where they convey released ova to they uterine cavity
Flagela
Long and Single
Moves entire cell
5.Spindle apparatus assembly
Centresomes
role in cell division
located within the cytoplasm close to the nucleus and consists of:
two centrioles, oriented at right angles to each other
nine circularly arranged triplet of microtubules
Before cell division, the centrosome duplicates.
Division begins, the two centrosomes move to opposite ends of the cell.
Composed of: Tubulin
