Cytoskeleton

Cytoskeleton

Cytoskeleton Be Humbled by the TruthGenesisThere are three types of filaments that create and support the innings of a cellMicrotubulesActin FilamentsIntermediate Filaments

But wait, theres more!!!

MicrotubulesMicrotubules of a cytoskeleton are straight hollow cylinders made up of tubulin monomers.

microtubule

The microtubules are the support of the cytoskeleton and also help in the transport of certain protein moleculesActin FilamentsAKA microfilaments.The finest of the three

Forms a band just beneath the plasma membrane

Generates locomotion in cellsEx: white blood cells

This is what youshould be looking at

ALSO, they interact with myosin filaments to provide the force of muscular contractions

Whoa!!

Intermediate FilamentsSeveral Types:KeratinsNuclear LaminaNeurofilamentsVimentins

They provide a supporting framework within the cell

Roles of CytoskeletonMaintains cell shapeProtects the cellEnables some cell motion (using structures such as flagella and cilia)Plays important roles in intra-cellular transport (the movement of vesicles and organelles) Plays important role in eukaryotic cellular division

Remember! The cytoskeleton is both a muscle and a skeleton, and is responsible for:Cell movementCytokinesisOrganization of the organelles within cell

The cytoskeleton acts as a "track" on which cells can move organelles, chromosomes and other things.

MotilitySpontaneous MotionProduct of evolutionThe cytoskeleton is very critical to cell motilityThe cytoskeleton system is a secondary source for cell motility
