| ovarian cystic disease | <gynaecology> A painful condition associated with the recurrent formation of large ovarian cysts. Distention of the ovarian capsule causes pain and rupture of a larger cyst can, in rare instances, cause internal bleeding. Treatment often includes hormone manipulation (birth control pills). (05 Jan 1998) |

| kidney, cystic | A kidney containing one or more cysts, including polycystic disease (kidney, polycystic), solitary cyst, multiple simple cysts, and retention cysts (associated with parenchymal scarring). (12 Dec 1998) |
| Luschka's cystic glands | Small, mucous, tubuloalveolar glands in the mucosa of the larger bile ducts and especially in the neck of the gallbladder. Synonym: glandulae mucosae biliosae, Luschka's cystic glands, Theile's glands. (05 Mar 2000) |
| lymphangioma, cystic | A lymphangioma, often very large, usually occurring in the neck area, and composed of large, multilocular thin-walled cysts. It is also called hygroma or cystic hygroma. (12 Dec 1998) |
| anterior tibial node | A small inconstant lymph node in front of the interosseous membrane along the upper part of the anterior tibial vessels. Synonym: nodus tibialis anterior, anterior tibial node. (05 Mar 2000) |
| artery to atrioventricular node | The atrioventricular branches or the nodal branches, the small arteries supplying the atrioventricular node; they usually arise from the right coronary artery where it starts to descend the posterior interventricular sulcus. Synonym: ramus nodi atrioventricularis, atrioventricular nodal branch, branch to atrioventricular node. (05 Mar 2000) |
| artery to the sinuatrial node | Ascending atrial branch, usually (55%) arising from the anterior stem of the right coronary artery (but 35-45% arising from the circumflex branch of the left coronary artery), which runs around the base of the superior vena cava to reach the sinuatrial node. Synonym: ramus nodi sinuatrialis arteriae coronaria dextra, branch to sinuatrial node, sinuatrial nodal branch of right coronary artery, sinuatrial node artery. (05 Mar 2000) |
| atrioventricular node | <cardiology> The location in the heart's conduction system, between the atria and the ventricles, which conducts the normal electrical impulse from the atria to the ventricles. (27 Sep 1997) |
| A-V node | <cardiology> The location in the heart's conduction system, between the atria and the ventricles, which conducts the normal electrical impulse from the atria to the ventricles. (27 Sep 1997) |
| axillary node | <anatomy> The lymph nodes in the axilla (underarm) that are cut out and examined during surgery to see if the cancer has spread past the breast. The number of nodes in this area varies. (09 Oct 1997) |
| branch to atrioventricular node | The atrioventricular branches or the nodal branches, the small arteries supplying the atrioventricular node; they usually arise from the right coronary artery where it starts to descend the posterior interventricular sulcus. Synonym: ramus nodi atrioventricularis, atrioventricular nodal branch, branch to atrioventricular node. (05 Mar 2000) |
| branch to sinuatrial node | Ascending atrial branch, usually (55%) arising from the anterior stem of the right coronary artery (but 35-45% arising from the circumflex branch of the left coronary artery), which runs around the base of the superior vena cava to reach the sinuatrial node. Synonym: ramus nodi sinuatrialis arteriae coronaria dextra, branch to sinuatrial node, sinuatrial nodal branch of right coronary artery, sinuatrial node artery. (05 Mar 2000) |
| buccal node | One of the chain of facial lymph nodes located superficial to the buccinator muscle. Synonym: nodus buccinatorius, buccinator node, buccal node. (05 Mar 2000) |
| malar node | One of the facial lymph nodes located near the zygomatic minor muscle. Synonym: nodus malaris, malar node. (05 Mar 2000) |
| Ranvier's node | A short interval in the myelin sheath of a nerve fibre, occurring between each two successive segments of the myelin sheath; at the node, the axon is invested only by short, finger-like cytoplasmic processes of the two neighboring Schwann cells or, in the central nervous system, oligodendroglia cells. See: myelin sheath. (05 Mar 2000) |
