Microtubules are made of a dimer protein called tubulin. They grow in length by adding tubulin dimers, but they can also be disassembled. This process of assembly and disassembly makes the microtubule seem to move from one location of the cell to another.
Microtubules. Dynein proteins help move cargo along microtubules by sliding past one another in a process known as retrograde transport.
The cell's cytoskeleton, made up of microtubules and microfilaments, consists of hollow tubes that provide structure and support for the cell. These structures also play important roles in cell division, cell movement, and intracellular transport.
Another nickname for centrioles is "cellular organizers" due to their role in organizing the microtubules during cell division.
The macromolecule that builds both cilia and flagella is primarily tubulin, which forms microtubules. These microtubules are arranged in a specific pattern, typically a "9+2" arrangement in eukaryotic cells, providing structural support and enabling movement. Additionally, proteins such as dynein and kinesin play crucial roles in the movement of cilia and flagella by facilitating the sliding of microtubules against one another.
Centrioles are like spindles. A Centriole is like a straw because they both are tubes that let things get from one end to the other end. The centriole has a round look to it because it is made from nine triplets of microtubules that make a straw-like(as said above) look. A centriole is like a clothing rack because centrioles organize cell division and clothing racks organize sizes of clothing
Someone on another qustion that was exactly like yours said microtubules, so I hope that helps you out (:

Another name is the cytoskeleton of the cell.

Cytoskeleton does not have any synonyms. The cytoskeleton refers to a cell's framework. It is made up of microtubules and filaments.
An axopodium is another word for an axopod - any of a group of pseudopods which contain complex arrays of microtubules and are enveloped by cytoplasm.
A mass structure can have only one center of gravity, which is the point where the entire weight of the structure is considered to act. This point represents the average location of the mass distribution of the structure.
A structure that is a member of another structure is a structure within a structure.
When it comes to mitosis, this process is facilitated by a subgroup of microtubules known as astral microtubules, which are microtubules originating from the centrosome that do not connect to a kinetochore. Astral microtubules develop in the actin skeleton and interact with the cell cortex to aid in orientation of spindles during cell division. They are organized around the centrosomes into radial arrays. Astral microtubules function in in tandem with specialized dynein motors, which are oriented with the light chain portion attached to the cell membrane and the dynamic portion which is attached to the microtubule. This allows for dynein contraction to pull the centrosome towards the cell membrane, thus assisting in cytokinesis in plants and animals. Microtubules act as conveyer belts inside cells. They help to move vesicles, granules and organelles like mitochondria, and chromosomes via special attachment proteins. Vesicles get attached to microtubule associated proteins and move along the microtubule conveyer belt. The microtubule associated proteins include kinesins and dynein which move along the microtubules in opposite directions. Kinesins move vesicles along towards the plus end and dynein moves towards the minus end. This is how vesicles are moved from one region to another. This is active transport and hence, requires the breakdown of ATP, though it is not yet known how the energy from ATP breakdown is converted into vectorial transport. Also, it is microtubules that join with other proteins to form more complex structures called cilia, flagella or centrioles. Microtubules also play a role in maintaining the cytoskeleton, that is, the basic structure of the cell. This is because, structurally, they are linear polymers of tubulin which is a globular protein present in the cytoplasm. Read more on cytoplasm function in a cell. This was all about the structure and function of microtubules in a cell. Microtubules functioning and formation can be disrupted by the use of certain drugs. This is the basis of using certain drugs like colchicine which help to treat cancer. These drugs inhibit polymerization by binding to tubulin and preventing its addition to the (+) ends. { Q. Does anyone know .... what do the microtubules form between the centrioles? A. They form Bridges. }
Apparently there will be a 6th and 7th
