tubule

 [too´būl]
a small tube; especially, a minute canal found in various structures or organs of the body. adj., adj tu´bular.
collecting t's the terminal channels of the nephrons, which open on the summits of the renal pyramids in the renal papillae.
convoluted t's channels that follow a tortuous course; there are convoluted renal tubules and convoluted seminiferous tubules.
dentinal t's the tubular structures of the teeth.
galactophorous t's small channels for the passage of milk from the secreting cells in the mammary gland.
Henle's t's the straight ascending and descending portions of a renal tubule forming Henle's loop.
lactiferous t's galactophorous tubules.
mesonephric t's the tubules comprising the mesonephros, or temporary kidney, of amniotes.
metanephric t's the tubules comprising the permanent kidney of amniotes.
renal tubule the minute canals composing the substance of the kidney and secreting, collecting and conducting the urine; in the glomerulus they have a basement membrane and epithelial lining.
seminiferous t's the tubules of the testis, in which spermatozoa develop and through which they leave the gland.
uriniferous t's renal tubules; channels for the passage of urine.

Most diuretics are secreted into the proximal convoluted tubule and act on the surface of the cells lining the tubules.
In the present SEM study Group B samples (Pro-Argin) showed more number of dentinal tubule occlusions when compared with Group C (Clinpro) and Group A samples.
Dentine Hypersensitivity [DH] is a common occurrence and under extreme conditions when dentine tubules is exposed to the oral cavity patients will experience a short, sharp pain.
Staining of sections was done with Hematoxylin and Eosin (HandE) for routine histological study and Periodic Acid Schiff Hematoxylin (PASH) for demonstration of basement membrane and microvilli of renal tubules. Tubular diameters were measured by ocular micrometer which was calibrated by a stage micrometer at 40X objective power.
A common set-back of established renal proximal tubule cell models in vitro is the reduction or even loss of inherent transporter expression.
c: cortex; om: outer medulla; im: inner medulla, pt: proximal tubule; npt: nonproximal tubule; g: glomerulus.
Selective SGLT-2 inhibitors reduce renal glucose reabsorption by inhibiting SGLT-2 in the kidney, thus reducing the maximum glucose transport capacity in the proximal renal tubule and increasing renal glucose excretion.
Sections were stained with hematoxylin-eosin to assess the integrity of the tissue and the structure of seminiferous tubules. The following staining methods were used: Weigert's resorcin fuchsin with previous oxidation to observe elastic system fibers and picrosirius red with polarization for observation of different collagen types.
iNOS mRNA has been detected in the S3 segment of the proximal tubule, mTAL, distal convoluted tubule, cortical collecting duct, and inner medullary collecting duct [36].
Class V Regression: After completing spermiation, the testis shows a reduction in the tubule diameter; towards the distal area shows remaining spermatozoa and a discontinuous and thin germinal epithelium (8.587 [+ or -] 0.419 [micro]m).
However, there was considerable variation among tubule diameter in the hinny.
