| metanephric duct | The slender tubular portion of the metanephric diverticulum; the primordium of the epithelial lining of the ureter. See: epoophoron, longitudinal duct of epoophoron. (05 Mar 2000) |
|---|---|
| persistent mullerian duct syndrome | <syndrome> Familial disorder with presence of fallopian tube, uterus, and testis in a male. Deficient mullerian inhibitory substance secondary to Sertoli cell defect. Synonym: hernia uteri inguinale. (05 Mar 2000) |
| choledoch duct | <anatomy> A duct that carries bile from the liver and gallbladder to the duodenum (first part of the small intestine). (27 Sep 1997) |
| guttural duct | A tube leading from the tympanic cavity to the nasopharynx; it consists of an osseous (posterolateral) portion at the tympanic end, and a fibrocartilaginous (anteromedial) portion at the pharyngeal end; where the two portions join, in the region of the sphenopetrosal fissure, is the narrowest portion of the tube (isthmus); the auditory tube enables equalization of pressure within the tympanic cavity with ambient air pressure, referred to commonly as "popping of the ears". Synonym: tuba auditiva, tuba auditoria, eustachian tube, guttural duct, otopharyngeal tube, otosalpinx, pharyngotympanic tube, salpinx, tuba acustica, tuba eustachiana, tuba eustachii. (05 Mar 2000) |
| cochlear duct | Spiral tube in the bony canal of the cochlea, lying on its outer wall between the scala vestibuli and scala tympani. (12 Dec 1998) |
| Wharton's duct | The duct of the submandibular salivary gland; it opens at the sublingual papilla near the frenulum of the tongue. Synonym: ductus submandibularis, ductus submaxillaris, submaxillary duct, Wharton's duct. (05 Mar 2000) |
| common bile duct | <anatomy> A duct that carries bile from the liver and gallbladder to the duodenum (first part of the small intestine). (27 Sep 1997) |
| common bile duct calculi | The presence of gallstones in the common bile duct. It is usually the result of passage of gallstones formed in the gallbladder into the common duct. Less commonly, stones form in a duct behind an obstruction caused by a stricture or ampullary stenosis. Stone type helps to determine site of origin: cholesterol or black pigment stones more likely form in the gallbladder, while almost all brown pigment stones in patients from western countries form in the bile ducts. (12 Dec 1998) |
| common bile duct diseases | Diseases of the common bile duct, vater's ampulla, or oddi's sphincter. (12 Dec 1998) |
| common bile duct neoplasms | Neoplasms of the common bile duct including vater's ampulla and oddi's sphincter. (12 Dec 1998) |
| common duct | <anatomy> This is the main bile duct, which is formed as the right and left hepatic bile ducts join, this common duct empties bile into the duodenum. (09 Oct 1997) |
| 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) |
