| omphalomesenteric duct cyst | Cystic lesion found within the umbilical cord, presumed to develop from remnants of the omphalomesenteric duct early in gestation. May be found on antenatal ultrasound. Synonym: omphalomesenteric duct cyst. (05 Mar 2000) |
| tectorial membrane of cochlear duct | A gelatinous membrane that overlies the spiral organ (Corti) in the inner ear. Synonym: membrana tectoria ductus cochlearis, Corti's membrane, tectorium. (05 Mar 2000) |
| testicular duct | The secretory duct of the testicle, running from the epididymis, of which it is the continuation, to the prostatic urethra where it terminates as the ejaculatory duct. Synonym: deferent canal, deferent duct, spermatic duct, spermiduct, testicular duct, vas deferens. (05 Mar 2000) |
| thoracic duct | <anatomy> The major efferent lymph duct into which lymph from most of the peripheral lymph nodes drains. Recirculating lymphocytes that have left the circulation in the lymph node return to the blood through the thoracic duct. (18 Nov 1997) |

| 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) |
| thyroglossal duct cyst | A cyst in the midline of the neck resulting from nonclosure of a segment of the ductus thyroglossus. Synonym: cervical cyst. (05 Mar 2000) |
| thyrolingual 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) |
| efferent duct | One of 12 to 14 small seminal ducts leading from the testis to the head of the epididymis. Synonym: ductulus efferens testis, vas efferens, efferent duct. (05 Mar 2000) |
| ejaculatory duct | The duct formed by the union of the deferent duct and the excretory duct of the seminal vesicle, which opens into the prostatic urethra. Synonym: ductus ejaculatorius, spermiduct. (05 Mar 2000) |

| tympanic wall of cochlear duct | The wall that separates the cochlear duct from the scala tympani; it consists of the osseous spiral lamina and the basilar membrane. Synonym: paries tympanicus ductus cochlearis, membrana spiralis, spiral membrane. (05 Mar 2000) |
