In the future advances in the medical field have now been capable of limb regeneration. At a world conference one of the leading experts revealed she had been asked if she would grow (or attach) an additional limb on a person Person had a particular work requirement and a extra limb would be helpful for carrying out their work She promised to think, and investagate, the matter and to get back to the person. For the moment she would appreciate any views from any member of this conference Numerous problems sprang to mind. No ethical reason she could think of though So would you grow, or attach, a (any) extra appendage? Please Register or Log in to view the hidden image!
Well, yes. But it wouldn't work. So unless you want it for decoration, or to get in a freak show or something, it would just be insensate dead weight.
In an odd coincidence, I have been writing up a fictional sci fi character in the form of an enhanced German Shepherd with a humanlike arm prosthetic that is controlled by the nerves that normally go to its tail.
It's a given that it would work Interesting. I was the along the lines of an extra arm, or two even. Modify the shoulder joint to have two places for two humerus two arms forward two arms back During the procedure split the original median nerve, radial nerve and ulnar nerve to join with the new arm equivalents. Let the brain work out how to control the new arm(s) Please Register or Log in to view the hidden image! Please Register or Log in to view the hidden image!
everything is balanced as a dual sided process & co-ordination would be important if you dont have the muscle structure attached to the right positions you wont be able to use the extra arm or leg what about an extra finger ? how would you operate it ? would be popular with musicians extra organs might be good like extra kidneys and extra liver would it turn out to require twice as much energy to only achieve the same level of work ? the heart would need to be increased in size
The heart does increase in size as its work load increases Sure why not? Branch off a nerve to make a new nerve pathway to (within) the new finger from a adjacent finger. I'm guessing a LOT of exercise manipulation of the new finger will be required to inform the brain of its extra responsibility (operating the new finger) Will the brain twig it has a new finger grown / surgically attached to the body? Another guess that grown would be best option Please Register or Log in to view the hidden image!
Are we special-ordering people fitted to specific jobs? What if we did that and the job became obsolete? Do we remove the specialized limb and fit the worker with a different appendage, or make the whole person redundant? Sure. I've always wanted a long, prehensile tentacle. It would go in the upper back, attached to the spinal cord, and usually stay curled up flat, like a compact backpack. When required, I could uncoil it to pull things behind me, or guide rolling luggage at either side, or reach around to the front over either shoulder, or at waist level, to act as third hand. be pretty useful as a defensive weapon, too. If it's attached to the nervous system, the brain would have acknowledge it, but might not understand what is. You would have to train a whole new neural pathway to operate it - consciously at first, the way you use power tools; eventually, it would become automatic.
No the decision to add extra appendage made by the person themselves To be worked out between person and surgeon Being made redundant happens now with automation Imagine eBay ad in future "One extra appendage willing to be donated to suitable person In excellent young 4 years of age healthy condition. Only being removed because no longer required" May you live long enough to have wish granted Sounds like you have already been working on some details Please Register or Log in to view the hidden image! It would have to be Of course acknowledge. Not sure about the understand since obviously one section of the brain KNOWS you have added the extra appendage My thoughts on how to achieve - consciously - would be to have the appendage moved to a position and monitor the nerve impulses going back to the brain. Repeat until the brain understands said nerve impulses SENT the appendage would move it into the position Please Register or Log in to view the hidden image!
Yes, but not what it is, what it's supposed to do or how to control it. None of this information is in the DNA, and it didn't form in the neural networks in utero or infancy, as it would have done all the other organs and appendages. We already have that technology. https://www.sciencedaily.com/releases/2017/02/170206084904.htm
And the next thing I'll want is a pair of wings with a photovoltaic upper surface, so it would power itself in flight and act as both shelter and heat source at rest. (Of course I've thought about this! What sf aficionado hasn't?)
Better get the body muscle strength to flap the wings Please Register or Log in to view the hidden image! While I have considered the possibility, never considered applying said technology to myself, with flying being the exception Please Register or Log in to view the hidden image!

Like what guys? Anyway generate(ing) their own energy to flap is one aspect, (up down, up down) along with a seperate strong muscular system needed to keeping wings attached along with another system which has the ability to twist tendons (?) needed for charging the aerodynamics of the wing Personally I would like said required energy to come from nourishment not sunlight Please Register or Log in to view the hidden image!
