Minute canals, consisting of a basement membrane and a lining of epithelium, which form the proper glandular substance of the kidney. They originate in Bowman's capsules, and, after extending in a tortuous manner for a considerable distance, finally join other t's to form a common t., which extends in a nearly straight direction, and, after joining others, empties into the pelvis of the kidney. While the uriniferous t's may be properly said to be continuous from their origin to their termination, various parts of their length differ in size and course and in the character of the lining epithelium, and are named as if they were independent t's, as follows: (1) The capsule of Bowman; (2) the neck or constricted part joining the t. and capsule; (3) the first convoluted t.; (4) the spiral t. of Schachowa; (5) the descending limb of Henle's loop tube; (6) Henle's loop tube; (7) the ascending limb of Henle's loop tube; (8) the irregular t.; (9) the second convoluted t.; (10) the junctional t., the last uniting with other junctional t's to form (11) a collecting t, which unites with others to form (12) an excretory t., which finally opens into one of the calices of the pelvis of the kidney.[Lat.]

Proto Oncogene Proteins c erbB 2
- cell surface protein-tyrosine kinase that is found to be overexpressed in significant number adenocarcinomas. It has extensive homology can heterodimerize EGF EPIDERMAL GROWTH FACTOR), 3 receptor (RECEPTOR, 3) and the 4 receptor. Activation of erbB-2 receptor occurs during heterodimer formation with a ligand-bound erbB family members. EC 2.7.11.-.
