WEAKNESS- (3584 words) |
 | Because the anterior horn cells that innervate different muscles in the upper and lower extremities are present at different segments of the spinal cord, a whole extremity is not presented at a single level. |
| Because one anterior horn cell/motor axon innervates a number of muscle fibers, it follows that disease of an anterior horn cell or its axon results in denervation of a number of muscle fibers. |
| With damage to an anterior horn cell or a motor axon the denervated muscle fibers usually become reinnervated by another motor axon with the result that more muscle fibers are innervated by the same anterior horn cell or motor axon in close proximity to the EMG needle. |
