A connecting wire is run under the skin from the stimulator to an electrode that is attached to the vagus nerve, which is accessible through a small incision (cut) in the neck.
A long ton is defined as exactly 2,240 pounds. The long ton arises from the traditional British measurement system: A long ton is 20 cwt, each of which is 8 stone (1 stone = 14 pounds). Thus a long ton is 20 Ã 8 Ã 14 lb = 2,240 lb.
In the United States and formerly Canada a ton is defined to be 2,000 pounds (907 kg). Where confusion is possible, the 2240 lb ton is called  long ton  and the 2000 lb ton  short ton ; the tonne is distinguished by its spelling, but usually pronounced the same as ton, hence the US term metric ton.here confusion is possible, the 2240 lb ton is called  long ton  and the 2000 lb ton  short ton ; the tonne is distinguished by its spelling, but usually pronounced the same as ton, hence the US term metric ton.
