What is another word for microtubule?
Pronunciation: [mˌa͡ɪkɹə͡ʊtjˈuːbjuːl] (IPA) 
Microtubules are hollow tubes made up of protein. They are a crucial part of the cellular cytoskeleton and play a vital role in various cellular processes like cell division, cell movement, and intracellular transport. While 'microtubule' has long been the accepted term to describe these structures, there are several synonyms or alternative words that can be used, including "tubulin polymers", "microfilaments", and "tubules". Another synonym that is sometimes used is "mitotic spindle fibers", which refers explicitly to the microtubules that make up the spindle apparatus during cell division. In summary, while "microtubule" is the standard term, there are many other options available to describe this critical cellular component.
