Cytoskeleton:

1. Microtubules: straight hollow rods measuring about 25 nm. thick . They are constructed from a and b tubulin. They shape, support and help move organelles around the cell. They form centrioles, which are not found in plants. They have a "9 + 2 " pattern.
2. Microfilaments: are constructed of 2 interwoven pieces of actin about 7nm. in diameter. They function in muscle contraction, cytoplasmic streaming, ameboid movement, and changes in cell shape.
3. Intermediate filaments, 8 to 11 nanometers in diameter, are more unstable (strongly bound) than actin filaments, and heterogeneous constituents of the cytoskeleton. They organize the internal structure of the cell and are structural components of the nuclear envelope.

3 main types of cytoskeleton are:-
(1) Microfilaments.
(2) Microtubules.
(3) Intermediate filaments.

microfilaments are made by actine which is one type of protine.
microetubules are made by tubuline which is one type of protine.
Intermediate filaments are also protines. they make a basket of filaments.
they give strength to a cell.

hi the main component of cytoskeleton is proteins that support the cell ,hold organelles in place,and enable the cell to change shape. The cytoskeleton consists of microtubles, microfilaments, and intermediate filaments.
