CYTOSKELETONS Meaning and
Definition
-
Cytoskeletons are complex networks of protein filaments found in the cytoplasm of cells. They serve as a structural framework that provides shape, support, and organization to the cell, as well as playing vital roles in cell movement, division, and intracellular transport.
The cytoskeleton can be thought of as the cell's internal skeleton, consisting of three main types of protein filaments: microfilaments, intermediate filaments, and microtubules. Microfilaments are the thinnest filaments, made up of the protein actin, and are involved in cell contraction, shape changes, and cell crawling. Intermediate filaments are intermediate in size and structural complexity, providing mechanical strength and support to the cell. They are made up of different fibrous proteins and their composition varies across cell types. Microtubules are the largest filaments, composed of the protein tubulin, and play crucial roles in cell division, intracellular transport of organelles, and maintaining cell shape.
The cytoskeleton is a highly dynamic and adaptable system that can be rearranged to suit cell needs. It is regulated by various cellular processes, including phosphorylation and dephosphorylation of proteins, as well as by molecular motors that move along the filaments, generating forces for cell movement and transport.
In summary, cytoskeletons are intricate networks of protein filaments that provide structural support, shape, and organization to cells. They are essential for cell movement, division, and intracellular transport, and play a crucial role in maintaining overall cellular integrity.

Etymology of CYTOSKELETONS
The term "cytoskeleton" is derived from two Greek words: "cyto" meaning "cell" and "skeleton" meaning "a bony framework". Together, "cytoskeleton" refers to the internal framework or structure of a cell. It was coined in the 1960s to describe the network of protein filaments and tubules that form a structural framework within the cytoplasm of cells. The plural form, "cytoskeletons", is simply the pluralization of the word.
