triquetrum
This term is used in two highly specialized domains: anatomy and the history of science. In a medical or biological context, it refers to a specific carpal bone. Because it is a technical anatomical term, it is almost exclusively found in clinical reports, surgical textbooks, or academic discourse regarding the skeletal structure of the wrist.
In the context of historical astronomy, the word describes an ancient sighting instrument. This usage is restricted to scholarly discussions of archeoastronomy or the evolution of scientific tools. Users must rely on the surrounding technical terminology to distinguish between the biological bone and the mechanical device.
