| foraminal lymph node | <anatomy> One of the hepatic nodes located adjacent to the epiploic foramen. Synonym: nodus foraminalis, foraminal node. (05 Mar 2000) |

| lateral lacunar lymph node | A lymph node of the external iliac group located lateral to the external iliac artery at the vascular lacuna. Synonym: nodus lacunaris lateralis, lateral lacunar node. (05 Mar 2000) |
| lymph node | <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) |
| lymph node excision | Surgical excision of one or more lymph nodes. Its most common use is in cancer surgery. (12 Dec 1998) |
| lymph node of azygos arch | A lymph node of the posterior mediastinal group located adjacent to the arch of the azygos vein. Synonym: nodus lymphaticus arcus venae azygos. (05 Mar 2000) |
| lymph node of ligamentum arteriosum | A lymph node of the anterior mediastinal group located adjacent to the ligamentum arteriosum. Synonym: nodus ligamenti arteriosi, lymph node of ligamentum arteriosum. (05 Mar 2000) |
| lymph node permeability factor | A substance, released by lymphocytes when stimulated or damaged, that increases capillary permeability and the accumulation of mononuclear cells. (05 Mar 2000) |
| posterior group of axillary lymph nodes | Node's of the axillary region located along the subscapular vein and its tributaries; they receive afferent vessels from the dorsal surface of the thorax and scapular region, and send efferent vessels to the central group of lymph nodes. Synonym: nodi lymphatici axillares subscapulares, posterior group of axillary lymph nodes. (05 Mar 2000) |
| posterior mediastinal lymph nodes | Nodes located along the thoracic aorta; they receive vessels from the oesophagus, diaphragm, liver and pericardium and send efferents to the thoracic duct and bronchomediastinal lymphatic trunk(s). Synonym: nodi lymphatici mediastinales posteriores. (05 Mar 2000) |
| anterior tibial artery | <anatomy, artery> Origin, popliteal; branches, posterior and anterior tibial recurrent, lateral and medial anterior malleolar, dorsalis pedis, lateral tarsal, medial tarsal, arcuate, dorsal metatarsal, and dorsal digital. Synonym: arteria tibialis anterior. (05 Mar 2000) |
| anterior tibial bursa | <anatomy> The small bursa between the medial surface of the medial cuneiform bone and the tendon of the tibialis anterior. Synonym: bursa subtendinea musculi tibialis anterioris, anterior tibial bursa. (05 Mar 2000) |
| anterior tibial compartment syndrome | <syndrome> Ischemic necrosis of the muscles of the anterior tibial compartment of the leg, presumed due to compression of arteries by swollen muscles following unaccustomed exertion. (05 Mar 2000) |
| anterior tibial muscle | <anatomy, muscle> Origin, upper two-thirds of lateral surface of tibia, interosseous membrane, and intermuscular septum; insertion, medial cuneiform and base of first metatarsal; action, dorsiflexion and inversion of foot; nerve supply, deep peroneal. Synonym: musculus tibialis anterior, anterior tibial muscle, musculus tibialis anticus. (05 Mar 2000) |
| anterior tibial nerve | <anatomy, nerve> One of the terminal branches of the common peroneal nerve, arising at the fibular neck and passing into the anterior compartment of the leg; it supplies the tibialis anterior, extensor hallucis longus, extensor digitorum longus, and peroneus tertius muscles in the leg, then crosses the ankle joint to supply the muscles on the dorsum of the foot (extensors hallucis and digitorum brevis) becoming cutaneous to innervate adjacent sides of the great and second toes. Synonym: nervus fibularis profundus, nervus peroneus profundus, anterior tibial nerve, deep fibular nerve. (05 Mar 2000) |
| anterior tibial recurrent artery | <anatomy, artery> A branch of the anterior tibial artery which ascends to supply the front and sides of the knee joint, thus contributing to the articular network of the knee. Synonym: arteria recurrens tibialis anterior. (05 Mar 2000) |
