Hi
Im sure one of you clever people know how to explain this. I thought there would be a good youtube clip but there isnt.
I just want to know the principle of how the full muscle dies and how long it takes with als. Once the motor neurons start dying do the rest go on mass.
i know that a motor neuron is a circuit to the muscle fibers. I get that once the circuit is broken, the muscle fibers die from lack of use. But how does it work with the whole muscle failing.
i keep hearing als is about failing not feeling. So for example standing on your tiptoes becomes impossible once the muscle dies. Its not that it gets harder its impossible. I get that the circuit is gone and the muscle doesnt move. But ive also read that its not about feeling.... so if you could lift a dumbell 10 reps and now you can.only do 5 reps thats not als. I dont get that bit. surely theres a time when the muscle is not yet fully dead, when its weak from some motor neurons dying but not all. Surely thats means you can do 5 reps instead of 10. So why is als not about feeling.
so using a bicep as an example, there are 774 motor neurons and over 200k muscle fibres in a bicep. Do the neurons die one at a time over many months or years or do they die on mass so the muscle dies quickly at once? Ive read the fast twitch muscles die first, but is there then a gap before the other muscles die. How long would it normally take the fat twitch muscle fibers to die? Ii understand there are also motor pools? How do they fit in with the neuron dying?
The reason im asking is i felt weakness at least 18 months ago butรจฤ the arm is still moving. Its weak but it still functional. It moves at full speed and does exactly what i want. But its quite painful to lift heavy things as i can see nearly all of the muscles are thinner. Surely all the nuerons on some muscles would have all died if they go on mass in 18 months?
Maybe im getting myself confused with it all. Im an accountant so i try and understand all the logic.
