1. Standard nomenclature for structures of the kidney (1988 Commission of the International Union of Physiological Sciences). Shown are a short-looped (right side) and a long-looped, or juxtamedullary nephron (left side), together with the collecting system (not drawn to scale). A cortical medullary ray—the part of the cortex that contains the straight proximal tubules, cortical thick ascending limbs, and cortical collecting ducts—is delineated by a dashed line. 1, renal corpuscle (Bowman's capsule and the glomerulus; 2, proximal convoluted tubule; 3, proximal straight tubule; 4, descending thin limb; 5, ascending thin limb; 6, thick ascending limb; 7, macula densa (located within the final portion of the thick ascending limb); 8, distal convoluted tubule; 9, connecting tubule; 9*, connecting tubule of a juxtamedullary nephron that arches upward to form a so-called arcade (there are only a few of these in the human kidney); 10, cortical collecting duct; 11, outer medullary collecting duct; 12, inner medullary collecting duct.
