| Albarran y Dominguez' tubules | Minute submucosal glands or branching tubules in the subcervical region of the prostate gland, emptying for the most part into the posterior portion of the urethra. Synonym: Albarran y Dominguez' tubules. (05 Mar 2000) |

| malpighian tubules | One of the tubular or hairlike excretory organs arising from the midgut-hindgut junction of many arthropods. Two to several hundred such tubules may be present. They collect waste from the body fluids and discharge them into the hindgut. Malpighian refers to the italian anatomist marcello malpighi, 1628-1694. (12 Dec 1998) |
| paragenital tubules | Remnants of embryonic mesonephric tubule's, some of which form the paradidymis. (05 Mar 2000) |
| wolffian tubules | Remnants of the mesonephric tubule's in the female, contained within the epoophoron. Synonym: wolffian tubules. (05 Mar 2000) |
| Henle's tubules | The straight portions of the uriniferous tubule's that form Henle's loop, distinguished as the descending and ascending tubule's of Henle. (05 Mar 2000) |
| seminiferous tubules | The canals through which the testicular spermatozoa are conveyed to the rete testis. (12 Dec 1998) |
| Skene's tubules | The embryonic urethral glands which are the female homologue of the prostate. (05 Mar 2000) |
| dental tubules | Minute, wavy, branching tubes or canals in the dentin; they contain the long cytoplasmic processes of odontoblasts and extend radially from the pulp to the dentoenamel junction. Synonym: dental tubules, dentinal canals, dentinal tubules, tubuli dentales. (05 Mar 2000) |
| dentinal tubules | Minute, wavy, branching tubes or canals in the dentin; they contain the long cytoplasmic processes of odontoblasts and extend radially from the pulp to the dentoenamel junction. Synonym: dental tubules, dentinal canals, dentinal tubules, tubuli dentales. (05 Mar 2000) |
| kidney tubules, collecting | Straight tubes commencing in the radiate part of the kidney cortex where they receive the curved ends of the distal convoluted tubules. In the medulla the collecting tubules of each pyramid converge to join a central tube (duct of bellini) which opens on the summit of the papilla. (12 Dec 1998) |
| Kobelt's tubules | Remnants of the mesonephric tubule's in the female, contained within the epoophoron. Synonym: wolffian tubules. (05 Mar 2000) |
| acute renal failure | <nephrology> A sudden decline in renal function may be triggered by a number of acute disease processes. Examples include sepsis (infection), shock, trauma, kidney stones, kidney infection, drug toxicity (aspirin or lithium), poisons or toxins (drug abuse) or after injection with an iodinated contrast dye (adverse effect). Chronic renal failure represents a slow decline in kidney function over time. Chronic renal failure may be caused by a number of disorders which include long-standing hypertension, diabetes, congestive heart failure, lupus or sickle cell anaemia. Both forms of renal failure result in a life-threatening metabolic derangement. (27 Sep 1997) |
| aminoaciduria, renal | Impairment of renal tubular transport of amino acids. (12 Dec 1998) |
| back-pressure renal atrophy | <radiology> Caliectasis without obstruction, due to repeated episodes of obstruction, gradual loss of renal pyramids (12 Dec 1998) |
| base of renal pyramid | The outer broad part of a renal pyramid that lies next to the cortex. Synonym: basis pyramidis renis. (05 Mar 2000) |
