| Wirsung's duct | The excretory duct of the pancreas that extends through the gland from tail to head where it empties into the duodenum at the greater duodenal papilla. Synonym: ductus pancreaticus, Hoffmann's duct, Wirsung's canal, Wirsung's duct. (05 Mar 2000) |

| wolffian duct | <radiology> MALE, vas deferens, vasa efferentia Female, Gartner duct cyst, hydatid cyst of Morgagni, epoophoron, paroophoron Cf: mullerian (para-mesonephric) duct (12 Dec 1998) |
| wolffian duct carcinoma | A rare tumour of the female genital tract, most often the ovary, formerly considered to be derived from mesonephric rests. Two varieties are recognised: (1) clear cell carcinoma, so called because of its histologic resemblance to renal cell carcinoma, and now considered to be of muellerian duct derivation and (2) an embryonal tumour (called also endodermal sinus tumour and yolk sac tumour), occurring chiefly in children. The latter variety may also arise in the testis. (12 Dec 1998) |
| mullerian duct | <radiology> FEMALE, fallopian tubes, uterus, vagina Male, appendix testis, prostatic utricle anomalies: mullerian agenesis most likely to be absent uterus and vagina, incomplete fusion most likely to be bicornuate/double uterus, double vagina, both associated with renal agenesis Cf: wolffian duct (12 Dec 1998) |
| craniopharyngeal duct | The slender tubular part of the hypophysial diverticulum; the stalk of Rathke's pocket. Synonym: bucconeural duct, hypophysial duct. (05 Mar 2000) |
| posterior branch of right hepatic duct | Hepatic duct branch draining bile from posterior segments of right lobe of liver. Synonym: ramus posterior ductus hepatici dextri. (05 Mar 2000) |
| cupular caecum of the cochlear duct | The upper blind extremity of the cochlear duct. Synonym: caecum cupulare, cupular blind sac, lagena. (05 Mar 2000) |
| cystic duct | <anatomy> A bile duct that connects the gallbladder to the common bile duct. A gallstone that blocks the cystic duct can lead to inflammation and infection of the gallbladder. See: common bile duct. (27 Sep 1997) |
| cystic duct cholangiography | Radiography of the biliary system after introduction of contrast medium through the cystic duct. (05 Mar 2000) |
| cystic gall duct | The ductus leading from the gallbladder; it joins the hepatic duct to form the common bile duct. Synonym: ductus cysticus. (05 Mar 2000) |
| salivary duct | A type of intralobular duct found in some salivary glands that modifies the secretory product; it derives its name from extensive infolding of the basal membrane. Synonym: salivary duct, secretory duct. (05 Mar 2000) |
| salivary duct calculi | Small calculi found in the terminal salivary ducts may be referred to as salivary sand. Larger calculi (stones) are found in the larger ducts, such as stensen's duct and wharton's duct. (12 Dec 1998) |
| Santorini's duct | The excretory duct of the head of the pancreas, one branch of which joins the pancreatic duct, the other opening independently into the duodenum at the lesser duodenal papilla. Synonym: ductus pancreaticus accessorius, Bernard's canal, Bernard's duct, ductus dorsopancreaticus, Santorini's canal, Santorini's duct. (05 Mar 2000) |
| hemithoracic duct | An accessory thoracic duct, usually emptying into the thoracic duct but sometimes discharging independently into the right subclavian vein. Synonym: ductus hemithoracicus. (05 Mar 2000) |
| Hensen's duct | A short membranous tube passing from the lower end of the saccule to the cochlear duct of the membranous labyrinth. Synonym: ductus reuniens, canaliculus reuniens, canalis reuniens, Hensen's canal, Hensen's duct, uniting canal. (05 Mar 2000) |
