how does a cut finger get resewn back on with full functionality?
In: Biology
I dunno of this was already said…
The muscles that move fingers arent in the fingers so all that needs to be reattached for them to work are the tendons. Limbs oth have musculature in them that works then making reattachment for functionality much nore complex.

To build on this- how far away are we from reconstructing severed/damaged spinal chords in a similar fashion to restore use of disabled limbs?
Using microsurgery. The surgeon uses very fine sutures to reattach nerves and blood vessels. For the surgery to be fully successful, the detached part of the finger must be kept cool an surgery must take place as soon as possible.
