The operator has to place a needle in the vicinity of the nerve and inject a local anesthetic to accomplish a block.[1] A needle is a sharp object whereas, a nerve is a vulnerable structure. To simplify, a nerve is like a telephone cable with hundreds of tiny wires inside it. If a needle makes its way into the cable, it is likely to cut some wires; but the cable may still be functional. It is because not all wires are cut, but there may be functions that cannot be replaced because of specific transmission of the cut tiny wires are lost. In the nerve block analogy, it means that some connecting neurons will become dysfunctional
transiently or permanently.
