- Animal Eukaryotic Cell Components: Structure And Function
I posted a picture of the eukaryotic animal cell earlier, but it was simply a labeled diagram. Here we will go into each of the major parts of the cell, as well as each organelle's function, not to mention the overall structure of the cell. As the...

cytoskeleton
Term: cytoskeleton
Origin: Anc Greek
?????/kytos (=container, box)
Greek letter K is replased by latin C, like in word ?cycle? which is derived from word ?kyklos? and it is used as a combining form meaning ?cell? in the formation of compound words like cytochrome, cytogenetics etc.
????????/skeletos (= the group of bones of an animal body)
Ø ?????? /skello(=dry up) > ???????/scleros(=hard)
literally meaning ?cellular scaffolding?
Coined
In 1928 by Russian biologist Nikolai Koltzoff (1872?1940) who first postulated the existence of a cytoskeleton. According Koltzoff :

Each cell is a system of liquid components and rigid skeletons, which generate the shape, and even though we rarely see the skeletal fibrils in living and fixed cells which only means that these fibrils are very thin or that they are not distinguished by their refractive index form the surrounding colloidal solution?.
Electron micrograph has confirmed his assumption and reveals the presence of cytoskeleton fabric formed of microtubules, microfilaments and intermediate filaments.

Definition
Cytoskeleton is proteinecous network of cell which is composed of three well defined filamentous structures ? in the form of microtubules, microfilament and intermediate filaments.
