distal convoluted tubule

tubule /tu·bule/ (too´būl) a small tube.

---

collecting tubule  one of the terminal channels of the nephrons which open on the summits of the renal pyramids in the renal papillae.

connecting tubule  junctional t.

dental tubules , dentinal tubules dental canaliculi.

distal convoluted tubule  a distal, convoluted part of the ascending limb of the renal tubule, extending from the distal straight tubule to the junctional tubule.

distal straight tubule  part of the renal tubule primarily on the ascending limb, extending from the thin tubule to the distal convoluted tubule.

Henle's tubule  see under loop.

junctional tubule  a short, curved part of the distal end of the renal tubule, extending from the distal convoluted tubule to a collecting duct.

mesonephric tubules  those constituting the mesonephros of the embryo of an amniote.

metanephric tubules  those constituting the metanephros of an amniote.

pronephric tubules  the rudimentary tubules constituting the pronephros of an amniote.

proximal convoluted tubule  the most proximal part of the renal tubule, extending from the glomerular capsule to the proximal straight tubule.

proximal straight tubule  part of the descending limb of the renal tubule, extending from the proximal convoluted tubule to the thin tubule.

renal tubule  the minute reabsorptive canals made up of basement membrane and lined with epithelium, composing the substance of the kidney and secreting, collecting, and conducting the urine; see also nephron.

seminiferous tubules  channels in the testis in which the spermatozoa develop and through which they leave the gland, each comprising a convoluted portion and a straight terminal portion.

T tubules  the transverse intracellular tubules invaginating from the cell membrane and surrounding the myofibrils of the T system of skeletal and cardiac muscle, serving as a pathway for the spread of electrical excitation within a muscle cell.

thin tubule  part of the renal tubule where the walls are especially thin, extending from the proximal straight tubule to the distal straight tubule.

uriniferous tubule  renal t's.
