What Has Changed in the Last Century

Collier's description from 1921 — three veins of the neck, "the external, the anterior, and the internal jugular," returning blood from the head — is still what anatomy students learn, though modern texts usually add the small posterior external jugular as a fourth. What has moved is clinical rather than descriptive: the internal jugular is now one of the standard routes for central venous catheters, used for drug infusion, dialysis access and pressure monitoring, and since the 1990s such punctures are typically guided by bedside ultrasound rather than by feel for landmarks. Inspection of the jugular veins at the bedside, to judge venous pressure and heart function, also became a routine part of the cardiac examination during the twentieth century. The anatomy in this entry reads as well today as it did in 1921.
