<anatomy>
A transitory endodermal tube in the embryo, carrying thyroid-forming tissue at its caudal end; normally, the duct disappears after the thyroid has moved to its definitive location in the neck; its point of origin is regularly marked on the root of the adult tongue by the foramen caecum; occasionally, its incomplete regression results in the formation of cysts along its embryonic course.
See: pyramidal lobe of thyroid gland.
Synonyms: ductus thyroglossus, thyrolingual duct.
