Cell Biology/Cytoskeleton/Actin Filaments
Cytoskeleton[edit | edit source]
Cytoskeleton is the skeleton of the cell, constructed from proteins. They lie on cytoplasm, defining cell's shape, movement and many other functions. There are 3 types of them which we will discuss shortly.
Actin filaments[edit | edit source]
Actin filaments are strings anchored one end in the plasma membrane. They generates contractile forces, which helps the cell moves and changes shape.
Actin filaments are also called microfilaments because they are the thinnest in cytoskeleton family.
