Cytoskeleton. Illustration showing the main elements of the cytoskeleton, the internal support and transport network found in cells. The cell membrane (blue) is partially supported by structures such as microfilaments (purple), intermediate filaments (yellow), and microtubules (green). Also shown are cell organelles such as mitochondria (orange) and rough endoplasmic reticulum (pink), with ribosomes (red dots) on the rough endoplasmic reticulum.
