Etymology: "Neurofibril" is a plain technical compound, built from "neuro-" and "fibril." The first part comes from Ancient Greek "neûron," which originally meant a sinew, cord or tendon, the tough fibrous tissue that joins muscle to bone. The Greek word was later used for nerves as well, and the combining form "neuro-" carries that sense into modern scientific vocabulary. The second part, "fibril," is a diminutive of "fibre," from Latin "fibra," meaning a thread or filament. Put together, the term describes a very fine thread-like structure within the nerve cell. The word belongs to the scientific vocabulary of the nineteenth and twentieth centuries, when anatomists needed precise names for structures they could now see under the microscope, and it was coined from these classical building blocks rather than used by the ancient Greeks themselves.
