Microtubules, the third principal component of the cytoskeleton, are rigid hollow rods approximately 25 nm in diameter. Like actin filaments, microtubules are dynamic structures that undergo continual assembly and disassembly within the cell. They function both to determine cell shape and in a variety of cell movements, including some forms of cell locomotion, the intracellular transport of ...

en.wikipedia.org/wiki/Microtubule

Microtubules are polymers of tubulin that form part of the cytoskeleton and provide structure and shape to eukaryotic cells.Microtubules can grow as long as 50 micrometres and are highly dynamic. The outer diameter of a microtubule is between 23 and 27 nm while the inner diameter is between 11 and 15 nm. They are formed by the polymerization of a dimer of two globular proteins, alpha and beta ...

Microtubules are filamentous intracellular structures that are responsible for various kinds of movements in all eukaryotic cells. Microtubules are involved in nucleic and cell division, organization of intracellular structure, and intracellular transport, as well as ciliary and flagellar motility.

Microfilaments and microtubules are the parts of any organism's cells that provide strength and structural support. They are the major components of the cytoskeleton, a framework of proteins that give the cell its shape and prevent it from collapsing. They are also the ones responsible for cell movement, as in the ...

What are Microtubules? “Microtubules are microscopic, hollow tubes made of alpha and beta tubulin that are a part of the cell’s cytoskeleton.” Microtubules extend throughout the cell providing it with proper shape and keeping the organelles in place. They are the largest structures in the cytoskeleton and are about 24nm thick.

Microtubules are composed of a single type of globular protein called tubulin. Two Main Functions During mitosis or cell division, the centrosome and centrioles replicate and migrate to opposite ends of the cell.

en.wikipedia.org/wiki/Kinetochore

A kinetochore (/ k ɪ ˈ n ɛ t ə k ɔːr /, /-ˈ n iː t ə k ɔːr /) is a disc-shaped protein structure associated with duplicated chromatids in eukaryotic cells where the spindle fibers attach during cell division to pull sister chromatids apart. The kinetochore assembles on the centromere and links the chromosome to microtubule polymers from the mitotic spindle during mitosis and meiosis.

Microtubules, the intra-cellular transport system, health and longevity. By Vince Giuliano. Image source. Microtubules play important and ever-changing structural roles in cells, play key roles in embryo development and cell division, are the basis for the intra-cellular molecular transport system, and most likely play important roles in gene activation and epigenetic processes.
