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.

C: The thick ascending limb of the loop of Henle is impervious to water, but actively transports sodium, potassium and chloride out of the tubules via the NaK-2Cl pump.
The total number of tubules and the number of occluded tubules were counted in each photomicrograph of all specimens.
Despite the enormous potential of eggshell-titanium dioxide bio composite, there is limited evidence in its use for occluding dentine tubules. The study aimed to synthesize Nano eggshell-titanium-dioxide (EB@Ti[O.sub.2]) bio composite and evaluate its effectiveness in occluding opened dentine tubules.
Amino acid sequence analysis of NXPH1 among 18 species revealed that the second structure of NXPH1 in species with sperm storage tubules was different from that in species without SST (Liu et al., 2013).
Score 2 = Moderate smear layer, No smear layer on the surface of the root canal, but tubules contained debris.
The external diameter of tubules was measured from the basement membrane of cells on one side of the tubule to the basement membrane of cells on the opposite side of the rounded tubules.
Indeed, solely providing RPTEC/TERT1 with a suitable extracellular matrix was sufficient to induce the development of in vivo-like proximal tubules without need of additional growth factors or cytokines.
Confocal analysis showed no significant differences among samples from WT, NaW-WT, and IRS2-KO mice (Figures 3(c)-3(e), resp.), but a great variability in PEPCK signal among proximal tubules from NaW-IRS2-KO mice was observed, with some proximal tubules showing enhanced reaction and others showing very poor levels (Figure 3(f)), which was further confirmed by a combination of PAS staining and PEPCK immunofluorescence (Figure 3(g)).
The mean number of tubules was 20.28+-3.29 in group A, 9.39+-3.01 in group B and 18.56+-2.82 in group C.
