Microtubules

Microtubules are fibrous components of cell cytoskeletons which interconnect the major organelles in each cell and through complex structures in the cell membranes called desmosomes and hemidesmosomes microtubules anchor cells to other cells and to the intracellular matrix support network that is largely composed of collagen fibers. in addition to maintaining the structure of cells along with other filamentous proteins they can be reorganized in a highly dynamic function to alter the internal structure of cells during cell division and in facilitating the movement of secretory vesicles, cell organelles, and other intracellular substances where other protein ‘motors’ transport them along microtubular ‘tracks’. They also form the primary structural framework for cilia and flagella protruding extracellularly, for the centrioles at the bases of cilia and flagella, and for microtubule organizing centers (MTOCS) which form in cell division. Microtubules are built of repeating subunits of a protein called Tubulin, which in the Orch OR theory of consciousness are quantum units existing in a state of superposition until ‘orchestration’ of their state collapse somehow results in consciousness.
