Biology 93
Cytoskeleton components
Cytoskeleton- network of fibers; throughout cytoplasm
Organizes structure and cell activity
3 types:
Microtubules
Thickest; hollow tubes
Maintain cell shapes and motility (movement)
Subunits of protein- tubular
https://en.wikipedia.org/wiki/Microtubule
Microfilaments
Thinnest
Called actin filaments because its protein subunit is actin
Made of 2 strands of actin
Helps maintain and change cell shapes, muscle contraction, and
also cell motility

Intermediate filaments
Middle range diameter
Coiled proteins
Protein subunits- several proteins like keratin
Maintains cell shape, anchors nucleus and organelles
