Cytoskeleton is one of the defining elements of eukaryotic cells.
In essence, the structure is the internal scaffold on which organelles are based, and the cytosols and vesicles in tissues, such as lysosomes.
There are two types of tubulin: α and β.
These proteins form hollow tubes, which form microtubules by forming filaments that bind together laterally.
Brain microtubules contain different types of tubulin, and have a variety of related proteins.
The composition of microtubules varies with the location of neurons, such as axons or dendrites.Depending on the unique environment provided by neurons,microtubules in the brain can specialize in different tasks
