|
Microtubules |
Structure: Hollow tubes Subunits: tubulin, a bimer, consisting of alpha-tubulin and beta tubulin Function: Maintains cell shape (compression resisting), Mobility (flagella), Organelle movement, Cell Division |
|
|
Intermediate Filaments |
Structure: fibrous protein coiled into cables Subunits: one of several proteins (like keratin) Function: Cell Shape (Tension-bearing elements), anchorage of nucleus and other organelles, formation of nuclear lamina |
|
|
Centrosomes |
a region that is located near the nucleus that grow micro tubules. |
|
|
Centrioles |
Come in pairs Composed of a nine sets of triplet microtubules arranged in a ring. Help arrange and organize microtubules in some cells |
|
|
Basal Body |
The base where flagellum or cilium attach too. (9+0 arrangement because the two Central Microtubules terminate above base) |
