The term embraces intermediate filaments, microfilaments, microtubules, the microtrabecular lattice, and other structures characterized by a polymeric filamentous nature and long-range order within the cell. The various elements of the cytoskeleton not only serve in the maintenance of cellular shape but also have roles in other cellular functions, including cellular movement, cell division, endocytosis, and movement of organelles.",IBA GO:0005925,CC,"focal adhesion","Small region on the surface of a cell that anchors the cell to the extracellular matrix and that forms a point of termination of actin filaments.",IDA GO:0006940,BP,"regulation of smooth muscle contraction","Any process that modulates the frequency, rate or extent of smooth muscle contraction.",TAS GO:0031032,BP,"actomyosin structure organization","A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of cytoskeletal structures containing both actin and myosin or paramyosin.
