The Cytoskeleton, Introduced
Captions available
The idea
The cytoskeleton is a network of protein fibers that maintains a cell's shape, anchors organelles, and moves cytoplasm, vesicles, or the whole cell.
In practice
Removing every organelle from a cell would still leave this fiber network holding its shape and internal organization.
Where people slip
The cytoskeleton is not one structure but three distinct fiber types, covered in the entries that follow.
