Following the surgical removal of many of her implants in 2374, former Borg drone Seven of Nine no longer had access to the instruments that were part of her thoracic assembly. She was therefore forced to resort to pulling out a data node that contained navigational data near her alcove in Voyager's cargo bay. (VOY: "Revulsion")
- As the thoracic region of the common humanoid includes the chest and not the limbs, the thoracic assembly cannot possibly refer to the ubiquitous Borg arm as many fans have speculated. Just how Seven of Nine intended to remove the data node with her chest...is best left to the imagination.
