Figure 1.

The diagram of nerve cell showing different inset images of the active nature of the actin and microtubule cytoskeleton. (E) Mixed polarity of the microtubules exists in the dendrites of the neurons. (C) Positive ends are laid down in the axonal shaft for efficient bidirectional axonal transport. (A) The actin patches have been magnified in the inset image to show their presence in the axonal shaft. These actin patches act as a source to create further branches arising at different lengths of the axon. Further magnification of actin and microtubule images represent molecular structures showing the active phenomena of actin polymerization (B) and microtubule polymerization (D) or nucleation with the help of different binding proteins.
