An umbilical cord functioned as a connection between pre-born mammals and their mothers. In 2366, Jean-Luc Picard described the android Lal's dependency on her "father" Data to Vice admiral Haftel by saying that the umbilical cord (in this case, metaphorical) was virtually uncut. (TNG: "The Offspring" ) In 2368, Worf cut Molly O'Brien's umbilical cord while delivering her when the USS Enterprise-D was experiencing the effects of a quantum filament. (TNG: "Disaster" )
