| encysted calculus | A urinary calculus enclosed in a sac developed from the wall of the bladder. Synonym: pocketed calculus. (05 Mar 2000) |

| jackstone bladder calculus | <radiology> Spiculated calculus in urinary bladder, calcium oxalate monohydrate (12 Dec 1998) |
| urethral calculus | A stone impacted in urethra. May have formed proximally and gotten stuck there or may have formed in urethra; uncommon. (05 Mar 2000) |
| fibrin calculus | A urinary calculus formed largely from fibrinogen in blood. (05 Mar 2000) |
| urinary calculus | A calculus in the kidney, ureter, bladder, or urethra. Synonym: urolith. (05 Mar 2000) |
| uterine calculus | A calcified myoma of the uterus. Synonym: hysterolith, uterolith. (05 Mar 2000) |
| lacrimal calculus | A concretion in the lacrimal apparatus. Synonym: lacrimal calculus, ophthalmolith, tear stone. Origin: dacryo-+ G. Lithos, stone (05 Mar 2000) |
| abdominal part of thoracic duct | The part of the thoracic duct between the cisterna chyli and the aortic hiatus of the diaphragm. Synonym: pars abdominalis ductus thoracici. (05 Mar 2000) |
| accessory pancreatic duct | The excretory duct of the head of the pancreas, one branch of which joins the pancreatic duct, the other opening independently into the duodenum at the lesser duodenal papilla. Synonym: ductus pancreaticus accessorius, Bernard's canal, Bernard's duct, ductus dorsopancreaticus, Santorini's canal, Santorini's duct. (05 Mar 2000) |
| alveolar duct | The part of the respiratory passages distal to the respiratory bronchiole; from it arise alveolar sacs and alveoli, the smallest of the intralobular duct's in the mammary gland, into which the secretory alveoli open. Synonym: ductulus alveolaris. (05 Mar 2000) |
| alveolar duct emphysema | Emphysema in which the primary involvement is in the alveolar ducts and respiratory bronchioles, as opposed to panacinar emphysema. (05 Mar 2000) |
| amniotic duct | The transitory opening between the seroamniotic folds in birds just before they fuse to form the seroamniotic raphe. (05 Mar 2000) |
| ampulla of milk duct | A circumscribed spindle-shaped dilation of the lactiferous duct just before it enters the nipple. In nursing mothers this dilatation stores a droplet of milk which is expressed by compression as the infant begins to suckle; this is thought to encourage continual suckling while the let-down reflex ensues. Synonym: sinus lactiferi, ampulla lactifera, ampulla of milk duct, lactiferous ampulla. (05 Mar 2000) |
| arch of thoracic duct | See: thoracic duct. (05 Mar 2000) |
| arterial duct | Before birth, the blood headed from the heart (via the pulmonary artery) for the lungs is shunted away from the lungs and returned to the greatest of arteries (the aorta). The shunt is through a short vessel called the ductus arteriosus. When the shunt is open, it is said to be patent (pronounced pa'tent). The patent ductus arteriosus (PDA) usually closes at or shortly after birth and blood is permtted from that moment on to course freely to the lungs. If the ductus stays open (patent), flow reverses and blood from the aorta is shunted into the pulmonary artery and recirculated through the lungs. The PDA may close later spontaneously (on its own) or need to be ligated (tied off) surgically. (12 Dec 1998) |
