Document Summary
Cytoskeleton provides structural support of a cell, it is like the skeleton of the cell contained within the cytoplasm. It maintains the cell shape and protects the cell and enabling cellular motions such as developing structures such as flagella and cilia. It also plays a role in intracellular transport and cellular division. There are mainly made up of 3 filaments, microfilaments (actin), intermediate filaments and microtubules. This shows a actin filament at the brush border of an epithelial cell, actin filament are also known as microfilament. It is made up of actin proteins joined in a long chain and it is the thinnest filament. It is made up of g- actin monomer linking into a chain called f- Actin polymer, which then pair off and interwind along eachother making it microfilament. They are found in a adherens junction and microvilli etc.
