Microtubules, which consist of heterodimers of о±-and оі-tubulin assembled into a dynamic polymeric structure, are involved in many cellular processes critical to proper cell function and survival.
Of microtubules and maps many aspects of the behavior of plant cells-indeed, of all eukaryotic cells- are influenced by microtubules and other components of the cytoskeleton, which give cells form and structure as well as providing for the mechanics of intracellu- lar transport and cell division. microtubule assembly is regulated in time and space, so that the appropriate microtubule arrays microtubules have many features that distinguish them from microfilaments and intermediate filaвments. to begin with, the outside diameter of a microвtubule (usually about вђ¦
The structure, function and dynamic behavior of the cytoskeleton can be very different, depending on organism and cell type.   even within one cell the cytoskeleton can change through association with other proteins and the previous history of the network. myocyte shearing, myocardial sheets, and microtubules andrew d. mcculloch, jeffrey h. omens t he cytoskeleton of cardiac myocytes is a complex network of many interacting protein filaments and
The function of microtubules microtubules are hollow, fibrous shafts whose main function is to help support and give shape to the cell. they also serve a transportation function, as they are the routes upon which organelles move through the cell. the function of centrioles therefore remains something of a mystery. structure a centriole is composed of short lengths of microtubules arranged in the form of an open-ended cylinder about 500nm long and 200nm in diameter.

Microfilaments. common to all eukaryotic cells, these filaments are primarily structural in function and are an important component of the cytoskeleton, along with microtubules вђ¦. Microtubules are found in all eukaryotic cells and are essential for many cellular functions, such as motility, morphogenesis, intracellular transport and cell division. it is that dynam-.

Quantum computation in brain microtubules вђ“ the penrose. Given these functions, cilia and flagella are micromachines and they act as cybernetic devices to receive, process and communicate information. key concepts structural concepts in ciliary/flagellar axoneme assembly and function include the template function of the basal body, the polarity of the microtubules and the enantiomorphic asymmetry (handedness) of the axoneme.. It has been claimed that the second major difference between anns and brain structure is that many types of anns (e.g. back-propagation, adaptive resonance, rce, sigma pi, etc.) use internal processing within each вђљneural elementв„ў..

The electropolarity arises from vibrations of microtubules composing the centrioles. mitosis begins as each centrioles duplicates itself by growing a daughter centriole on its side. if during duplication more than one daughter is grown, cancer can occur and the cells divide uncontrollably. cancer cells with supernumerary centrioles have high electropolarity which can serve as an attractor for the microtubule cytoskeleton is a remarkable structure that can adopt diverse architectures uniquely suited to the individual needs of a particular cell type or process.
