![]() This means that there will be many wrong numbers obtained after a repair. We know that not all of the inner cables (nerve fibres) will repair themselves and that many that do repair themselves get connected to the wrong house. It is only possible for the Surgeon to repair the outer layer but not the tiny inner cables (nerve fibres). Recovery from this type of injury is more unpredictable. For the nerve to recover the inner cables (nerve fibres) have to grow back down the tubes. The inner cable above the level of the injury remains alive as it is nourished by the nerve cells close to or within the spinal cord. To continue with the telephone cable analogy. When the inner cables (nerve fibres) are damaged the part of the cable that is beyond the level of the injury dies leaving an empty tube. This type of injury requires the nerve to be repaired if it is to recover. Here both the outer layer and inner cables (nerve fibres) are divided. Where the nerve is completely divided.Where the inner cables (nerve fibres) of the nerve are damaged but the outer layer remains intact.With this type of injury the nerve normally recovers fully and leaves no deficit. All the inner cables (nerve fibres) remain intact. Where the nerve is bruised and stops working properly for a short period of time.There are three basic types of injury to a nerve: The messages to the brain are information about feeling and from the brain to tell the muscles to contract. The inner cables are the wires that carry messages back and forth to the brain which is like a telephone exchange. There is an outer layer that protects the multiple thin inner cables (nerve fibres) that go to each house. ![]() ![]() A nerve is like a telephone cable that provides services to a number of houses. ![]()
