Jefferies Tubes

Jefferies

These are small tunnels or corridors that provide access to critical ship systems. They can be vertically or horizontally oriented, and sometimes form a network that allows travel throughout large volumes of a ship.

Jefferies Tunnel

The system of access tunnels and utilities corridors that carry much of the various utilities conduits and waveguides. The Jefferies Tube network covers the entire volume of the ship, providing access to utilities trunks and circuitry. Also located within these tubes are a variety of maintenance and testing points that allow the performance of various systems to be physically measured at key points throughout the ship."

The term "Jefferies tube" was originally a private gag among the original Star Trek production staff, a reference to Original Series art director Matt Jefferies, the man who designed the original starship Enterprise. The term quickly caught on among fans, becoming an official part of the show's lexicon, and has begun being used informally in some real-world situations to refer to similar access passages.
