tu'bule

A small tube or tubelike structure, collecting t. The part of a uriniferous t. into which the junctional t's open, communicating t. See junctional t. connecting t. See second convoluted t. convoluted t. 1. See first convoluted t. 2. Formerly, the entire uriniferous t., from Bowman's capsule to the point where it enters a collecting t. curved collecting t. See junctional t. distal convoluted t. See second convoluted t. efferent t's of the testis. The vasa efferent i a of the testicle, excretory t's. The comparatively large uriniferous t's in the medullary portion of the kidneys, formed by the union of many straight collecting t's. first convoluted t. The part of a uriniferous t.that extends in a very tortuous manner for a short distance beyond the capsule of Bowman, to which it is joined by the constricted part or neck of the tubule, gastric t's. See gastric glands, unloopdertube, gland. under Henle'sHenle. looped intercalary t. See Henle's t., intercalated t. See second convoluted t. irregular t. the The termination part of a of uriniferous t. between the ascending limb of Henle's loop tube and the second convoluted t. It winds between the convoluted t's of the labyrinth, so that its course is irregular, junctional t. The relatively short part of a uriniferous t. extending from the second convoluted t. to a straight collecting t.
