Nerve transection

[mbakula]

Hello guys and girls!

 

I have a question regarding nerves that I had hard time finding answer to - What happens to peripheral nerves after they are transected, such as amputation of a limb?

 

Particularly, what is going to happen to axon endings in the nerve stump over time (days, months) following transection, provided there is no distal nerve remant to promote regeneration.

 

From what I know for now, both efferent and afferent axons should live since their supporting neurons still exist (due to dorsal root ganglion neurons being pseudounipolar), however, I'd greatly appreciate more information about this!

 

Thanks a lot -
