Cell Types

Cytoskeleton

The cytoskeleton (cell skeleton) maintains the structure of animal cells and helps cells move. There are two types: Microtubules Microfilaments

Cytoskeleton M icrotubules are hollow tubes that act like scaffolding to maintaining a cell's shape and provide a path for organelle movement. Bundles of microtubules create structures useful for movement: cilia (short, hairlike) flagella (long, whiplike)

Cytoskeleton M icrofilaments are like a rope of two twisted protein chains. Microfilaments can contract, causing movement. The contraction of muscle is due to the action of microfilaments.
