| intercalated ducts | The minute duct's of glands, such as the salivary and the pancreas, that lead from the acini; they are lined by low cuboidal cells. (05 Mar 2000) |

| intercalated | Interposed; inserted between two others. Origin: L. Intercalatus (05 Mar 2000) |
|---|---|
| intercalated disc | An electron dense junctional complex, at the end to end contacts of cardiac muscle cells, that contains gap junctions and desmosomes. most of the disc is formed of a convoluted fascia adherens type of junction into which the actin filaments of the terminal sarcomeres insert (they are therefore equivalent to half Z bands), desmosomes are also present. The lateral portion of the stepped disc contains gap junctions that couple the cells electrically and thus coordinate the contraction. (18 Nov 1997) |
| intercalated disk | A specialised intercellular attachment of cardiac muscle comprising gap junctions, fascia adherens, and occasionally desmosomes. (05 Mar 2000) |
| intercalated nucleus | A small collection of nerve cells in the medulla oblongata lying lateral to the hypoglossal nucleus. Synonym: nucleus intercalatus, Staderini's nucleus. (05 Mar 2000) |
| aberrant bile ducts | Small duct's occasionally present in the ligaments of the liver or originating from the surface of the liver. (05 Mar 2000) |
| aberrant ducts | The superior or inferior diverticula of the epididymis. Synonym: ductuli aberrantes, aberrant ducts, ductus aberrantes, vasa aberrantes. (05 Mar 2000) |
| ampulla of the saemicircular ducts | A nearly spherical enlargement of one end of each of the three saemicircular ducts, anterior, posterior, and lateral, where they connect with the utricle. Each contains a neuroepithelial crista ampullaris. Synonym: ampulla membranacea, membranous ampulla. (05 Mar 2000) |
| ampullary crura of saemicircular ducts | The dilated ends of the three saemicircular ducts, each of which contains a specialised thickening of the epithelium known as the ampullary crest. Synonym: crura membranacea ampullaria ductus saemicircularis, ampullary limbs of saemicircular ducts. (05 Mar 2000) |
| ampullary limbs of saemicircular ducts | The dilated ends of the three saemicircular ducts, each of which contains a specialised thickening of the epithelium known as the ampullary crest. Synonym: crura membranacea ampullaria ductus saemicircularis, ampullary limbs of saemicircular ducts. (05 Mar 2000) |
| anal ducts | Short duct's lined with simple columnar to stratified columnar epithelium that extend from the valvulae anales to the sinus anales. (05 Mar 2000) |
| Bellini's ducts | The largest straight excretory duct's in the kidney medulla and papillae whose openings form the area cribrosa; they are a continuation of the collecting tubules. Synonym: Bellini's ducts. (05 Mar 2000) |
| bile ducts, extrahepatic | Passages external to the liver for the conveyance of bile. These include the common bile duct and the common hepatic duct (hepatic duct, common). (12 Dec 1998) |
| bile ducts, intrahepatic | Passages within the liver for the conveyance of bile. Includes right and left hepatic ducts even though these may join outside the liver to form the common hepatic duct. (12 Dec 1998) |
| canalicular ducts | The ducts, numbering 15 or 20, which drain the lobes of the mammary gland; they open at the nipple. Synonym: ductus lactiferi, canalicular ducts, galactophore, galactophorous canals, galactophorous ducts, mamillary ducts, mammary ducts, milk ducts, tubuli galactophori, tubuli lactiferi. (05 Mar 2000) |
| galactophorous ducts | The ducts, numbering 15 or 20, which drain the lobes of the mammary gland; they open at the nipple. Synonym: ductus lactiferi, canalicular ducts, galactophore, galactophorous canals, galactophorous ducts, mamillary ducts, mammary ducts, milk ducts, tubuli galactophori, tubuli lactiferi.
