Cytoskeleton

Nós do fluxograma

• Cytoskeleton-Structural support

• Intermediate filaments

• Microtubules

• Microfilaments

• made up of tubulin proteins, motor proteins kinesin and dynein move along them

• centrioles made up of triplets of microtubules

• attach at opposite ends of mitotic spindle

• attach to chromosomes -complex called kinetochoresand pull apart in anaphase

• make up cilia and flagella-movement

• sperm

• made up of actin

• ex-muscle cells, made up of actin + myosin 

• resistant to compression and fracture

• forms cleavage furrow in cytokinesis

• pinching off 2 daughter cells

• provide strong support, resistant to mechanical stress

• cell adhesions, keep cell structure rigid, anchor organelles
