Do axon grows after cutting of some of its part to near original place?

Do axon restores after local damaging of some of its part?

I take https://class.coursera.org/neurobio-001/ classes and learn that axons are very long. So it is interesting if they able to restore connection to far places parts of body...

    $\begingroup$ yes they do.. I'll post a long answer when i get time.. meanwhile you can look for Axonal regeneration. (A lot of experiments have been performed on regeneration of sciatic nerve and DRG neurons) $\endgroup$ – WYSIWYG May 23 '14 at 2:24

Well look at this picture from Junqueira histology book: enter image description here

In an injured or cut peripheral nerve, segments of axons distal to the injury lose their support from the cell bodies and degenerate completely. The proximal segments can regenerate from their cut ends after a delay. The main changes that take place in an injured nerve fiber are shown in the picture above.

In the nerve segment distal to the injury the axon and myelin, but not the connective tissue, degenerate completely and are removed by macrophages. While these regressive changes take place, Schwann cells proliferate within the connective tissue sleeve, giving rise to rows of cells that serve as guides for the sprouting axons formed during the reparative phase.

The axon grows at the rate of 0.5–3 mm/day
