| thyroglossal cyst | <anatomy, embryology> A thyroglossal cyst is a fluid-filled sac that is present at birth and located in the midline of the neck. A thyroglossal cyst is a result of incomplete closure of a segent of a tube-like structure (the thyroglossal duct) that is present, and normally closes, as the embryo develops. Synonym: thyrolingual cyst. (07 Mar 2000) |
| thyroglossal duct | 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. Synonym: ductus thyroglossus, thyrolingual duct. (05 Mar 2000) |
