| left colic lymph nodes | Small nodes along the left colic artery and its branches that drain the left flexure and upper part of the descending colon; efferent vessels pass to the inferior mesenteric nodes. Synonym: nodi lymphatici colici sinistri. (05 Mar 2000) |
|---|---|
| left gastric lymph nodes | Nodes located along the left gastric artery and its branches; they are divided into paracardial, upper and lower groups. Synonym: nodi lymphatici gastrici sinistri, superior gastric lymph nodes. (05 Mar 2000) |
| left gastroepiploic lymph nodes | Nodes located in the greater omentum along the left gastroepiploic artery that drain part of the greater curvature of the stomach and greater omentum. Synonym: nodi lymphatici gastro-omentales sinistri, left gastro-omental nodes. (05 Mar 2000) |
| left lumbar lymph nodes | The chain of lymph nodes associated with the aorta in the abdomen; it is divided into three groups: lateral aortic lymph nodes on the left of the aorta; pre-aortic lymph nodes in front of the aorta; post-aortic lymph nodes, behind the aorta. Synonym: nodi lymphatici lumbales sinistri, lumbar lymph nodes. (05 Mar 2000) |
| lingual lymph nodes | Lymph node along the lingual vein receiving drainage from the tongue (except tip); drain to submandibular lymph nodes. Synonym: nodi lymphatici linguales. (05 Mar 2000) |
| lumbar lymph nodes | right lumbar lymph nodes, intermediate lumbar lymph nodes, left lumbar lymph nodes |
| lymph | <physiology> The almost colourless fluid that bathes body tissues and is found in the lymphatic vessels that drain the tissues of the fluid that filters across the blood vessel walls from blood. Lymph carries lymphocytes that have entered the lymph nodes from the blood. (12 May 1997) |
| lymph capillary | The beginning of the lymphatic system of vessels; it is lined with a highly attenuated endothelium with poorly developed basement membrane and a lumen of variable caliber. See: lacteal. (05 Mar 2000) |
| lymph cell | <haematology> White cell of the blood that are derived from stem cells of the lymphoid series. Two main classes are recognised, T and B lymphocytes, the latter responsible (when activated) for production of antibody, the former subdivided into subsets (helper, suppressor, cytotoxic T-cells) and responsible both for cell-mediated immunity and for stimulating B-cells. (18 Nov 1997) |
| lymph circulation | The slow passage of lymph through the lymphatic vessels and glands. (05 Mar 2000) |
| lymph cords | Cord's of dense lymphoid tissue between the sinuses in the medulla of a lymph node. Synonym: lymph cords. (05 Mar 2000) |
| lymph corpuscle | Lymphatic corpusclelymphoid corpuscle, a mononuclear type of leukocyte formed in lymph nodes and other lymphoid tissue, and also in the blood. (05 Mar 2000) |
| lymph embolism | Lymphogenous embolism, embolism occurring in a lymphatic vessel. (05 Mar 2000) |
| lymph follicle | Lymphatic follicle, one of the spherical masses of lymphoid cells, frequently having a more lightly staining centre. See: solitary lymphatic follicles, Peyer's patches. Synonym: folliculus lymphaticus, lymph nodule, nodulus lymphaticus. (05 Mar 2000) |
| lymph gland | <anatomy> Small bean-shaped organ made up of a loose meshwork of reticular tissue in which are enmeshed large numbers of lymphocytes, macrophages and accessory cells located along the lymphatic system. Recirculating lymphocytes leave the blood through the specialised high endothelial venules of the lymph node and pass through the node before being returned to the blood through the lymphatic system. Because the lymph nodes act as drainage points for tissue fluids, they are also regions in which foreign antigens present in the tissue fluid are most likely to begin to elicit an immune response. Nodes filter out bacteria or cancer cells that may travel through the lymphatic system. Synonym: lymph glands. (14 Oct 1997) |
