Eukaroytic cells (those with a membrane-enclosed nucleus) have a great variety of complex shapes and are able to carry out coordinated and directed movement due to a complex, dynamic, internal scaffolding of proteins called the cytoskeleton. Many...

Neurons, like other cells, are not simply formless bags of CYTOPLASM: they have a structure provided by the cytoskeleton—literally, the cell skeleton. The cytoskeletons of neurons have three principal components. MICROFILAMENTS are thin fibres...

Eukaryotic cells contain these main kinds of cytoskeletal filaments. The cytoskeleton provides the cell's cytoplasm with structure and...
