microtubule

Cytoplasmic tubule, 25nm outside diameter with a 5nm thick wall. Made of tubulin heterodimers packed in a three-start helix (or of 13 protofilaments looked at another way), and associated with various other proteins (MAPs, dynein, kinesin). Microtubules of the ciliary axoneme are more permanent than cytoplasmic and spindle microtubules.

Microtubule

Microtubules are a component of the cytoskeleton, found throughout the cytoplasm. These tubular polymers of tubulin can grow as long as 50 micrometres, with an average length of 25 µm, and are highly dynamic. The outer diameter of a microtubule is about 24 nm while the inner diameter is about 12 nm. They are found in eukaryotic cells and are form...

microtubule

A slender, hollow, cylindrical filament found in the cytoskeleton of animal and plant cells. Microtubules not only provide a structural network within the cell's cytoplasm but also form a substrate on which other cellular chemicals can interact, are used in intracellular transport, and are involved ...
