Etymology: "Funiculus" is a Latin diminutive built from "funis," meaning "rope" or "cord," with the suffix "-culus" added to mark something small. A funiculus is, quite literally, a little rope. The same root gave English "funicular," the cable railway that hauls cars up a slope on a rope, so the word and its anatomical cousin share a picture of a cord under tension. The Latin diminutive suffix "-culus" appears in many scientific and anatomical terms, where it signals a small or slender version of something larger. In anatomy, the word is applied to thin fibrous strands that connect or support tissues, and the metaphor is the same one that made a child's string a "little rope." English adopted the term from Latin scientific usage, so the Latin itself, not the modern anatomy, carries the original sense.
