| LNL | lymph node lymphocyte |

| LNPF | lymph node permeability factor |
| MCLNS, MCLS | mucocutaneous lymph node syndrome |
| MLN | manifest latent nystagmus; membranous lupus nephropathy; mesenteric lymph node; motilin |
| MLNS | minimal lesion nephrotic syndrome; mucocutaneous lymph node syndrome |
| oxygen radical | <chemistry> Any oxygen species that carries an unpaired electron (except free oxygen). Examples are the hydroxyl radical and the superoxide anion. These radicals are very powerful oxidizing agents and cause structural damage to proteins and nucleic acids. They mediate the damaging effects of ionising radiation. (18 Nov 1997) |

| extended radical mastectomy | Excision of the entire breast including the nipple, areola, and overlying skin, as well as the pectoral muscles and the lymphatic-bearing tissues of the axilla and chest wall and internal mammary chain of lymph nodes. (05 Mar 2000) |
| free radical | A chemically active atom or molecular fragment containing a chemical charge due to an excess or deficient number of electrons. Radicals seek to receive or release electrons in order to achieve a more stable configuration, a process that can damage the large molecules within cells. See: Oxidation. (09 Oct 1997) |
| free radical reductase | <enzyme> Catalyses conversion of carbon-centreed lipid radicals into an inactive species by utilizing vitamin e at one end and glutathione at the other Registry number: EC 1.8.4.- (26 Jun 1999) |
| free radical scavengers | Substances that influence the course of a chemical reaction by ready combination with free radicals. Among other effects, this combining activity protects pancreatic islets against damage by cytokines and prevents myocardial and pulmonary perfusion injuries. (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) |
