| sphincter of hepatopancreatic ampulla | The smooth muscle sphincter of the hepatopancreatic ampulla within the duodenal papilla. Synonym: musculus sphincter ampullae hepatopancreaticae, Glisson's sphincter, hepatopancreatic sphincter, Oddi's sphincter. (05 Mar 2000) |
| duodenal ampulla | The dilated portion of the superior part of the duodenum. Synonym: ampulla duodeni. See: duodenal cap. Synonym: hepatopancreatic ampulla. (05 Mar 2000) |
| osseous ampulla | A circumscribed dilation of one extremity of each of the three bony saemicircular canals, anterior, posterior, and lateral; each contains an ampulla of the saemicircular ducts. Synonym: ampulla ossea, osseous ampulla. (05 Mar 2000) |
| Thoma's ampulla | A dilation of the arterial capillary beyond the sheathed artery of the spleen. (05 Mar 2000) |
| lactiferous ampulla | A circumscribed spindle-shaped dilation of the lactiferous duct just before it enters the nipple. In nursing mothers this dilatation stores a droplet of milk which is expressed by compression as the infant begins to suckle; this is thought to encourage continual suckling while the let-down reflex ensues. Synonym: sinus lactiferi, ampulla lactifera, ampulla of milk duct, lactiferous ampulla. (05 Mar 2000) |
| arcus ductus thoracici | See: thoracic duct. (05 Mar 2000) |
| artery of ductus deferens | Origin, anterior division of internal iliac, or sometimes superior vesical; distribution, ductus deferens, seminal vesicles, testicle, ureter; anastomoses, testicular, cremasteric arteries. Synonym: arteria ductus deferentis, arteria deferentialis, deferential artery. (05 Mar 2000) |
| vas prominens ductus cochlearis | A blood vessel in the substance of the spiral prominence of the cochler duct. (05 Mar 2000) |
| ramus lateralis ductus hepatici sinistri | Lateral branch left hepatic duct. See: lateral branches. (05 Mar 2000) |
| ramus medialis ductus hepatici sinistri | Medial branch of left hepatic duct. See: medial branches. (05 Mar 2000) |
| ramus posterior ductus hepatici dextri | Hepatic duct branch draining bile from posterior segments of right lobe of liver. Synonym: ramus posterior ductus hepatici dextri. (05 Mar 2000) |
| paries externus ductus cochlearis | The wall that faces the outer side of the cochlea. Synonym: paries externus ductus cochlearis. (05 Mar 2000) |
| paries tympanicus ductus cochlearis | 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) |
| paries vestibularis ductus cochlearis | The membrane separating the cochlear duct from the vestibular canal; it consists of squamous epithelial cells with microvilli toward the ductus, a basement membrane, and a thin layer of connective tissue toward the scala. Synonym: membrana vestibularis, paries vestibularis ductus cochlearis, Reissner's membrane, vestibular wall of cochlear duct. (05 Mar 2000) |
