Etymology: The hyoid is a U-shaped bone at the base of the tongue, and the urohyal is its counterpart in fish: a bony plate beneath the throat that anchors the gill arches and the muscles of the mouth floor. The name is built from two parts. The "hyal" element comes from the Greek letter "hyal" for the form of the bone, which is a Greek capital letter upsilon, so the word's first part, "uro-", is drawn from the same Greek letter, "ὖ" (û). Because the word is a modern technical coinage, its parts were put together deliberately by anatomists rather than inherited from ancient speakers. The "uro-" prefix and the "-hyal" ending combine into a label that describes the bone's shape and its position as a hyoid-like structure in fish. Ancient Greeks did not use the term, and it belongs to the scientific vocabulary built from classical roots.
