| 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) |
| mandibular lymph node | One of the facial lymph nodes located by the facial artery near the point it crosses the mandible. Synonym: nodus mandibularis, mandibular nodes. (05 Mar 2000) |
| paratracheal lymph node | Nodes along the sides of the trachea in the neck and in the posterior mediastinum; receive drainage of superior (and inferior) tracheobranchial (nodes, trachea and oesophagus); drain to bronchomediastinal lymphatic trunk(s), thoracic duct. Synonym: nodi lymphatici paratracheales, tracheal lymph nodes. (05 Mar 2000) |
| giant lymph node hyperplasia | Large benign, hyperplastic lymph nodes. The more common hyaline vascular subtype is characterised by small hyaline vascular follicles and interfollicular capillary proliferations. Plasma cells are often present and represent another subtype with the plasma cells containing IgM and IgA. (12 Dec 1998) |
| Virchow's node | A firm supraclavicular lymph node, especially on the left side, sufficiently enlarged that it is palpable from the cutaneous surface; such a lymph node is so termed because it may be the first recognised presumptive evidence of a malignant neoplasm in one of the viscera. A signal node that is known to contain a metastasis from a malignant neoplasm is sometimes designated by an old eponym, Troisier's ganglion. Synonym: jugular gland, Virchow's node. (05 Mar 2000) |
| medial lacunar lymph node | A lymph node of the external iliac group located medial to the external iliac vein at the vascular lacuna. Synonym: nodus lacunaris medialis, medial lacunar node. (05 Mar 2000) |
| medial lacunar node | A lymph node of the external iliac group located medial to the external iliac vein at the vascular lacuna. Synonym: nodus lacunaris medialis, medial lacunar node. (05 Mar 2000) |
| vital node | A circumscript region in the lower part of the medulla oblongata, near the apex of the calamus scriptorius, interpreted by M. Flourens (1858) as a nerve centre controlling respiration. Synonym: vital knot, vital node. Origin: Fr. (05 Mar 2000) |
| medulla of lymph node | The central portion of a node consisting of cordlike masses of lymphocytes, plasma cells, and macrophages in a stroma of reticular fibres separated by lymph sinuses; it reaches the surface of the node at the hilum. Synonym: medulla nodi lymphatici. (05 Mar 2000) |
| peroneal node | A small inconstant lymph node located along the course of the peroneal vein. Synonym: nodus fibularis, fibular node, peroneal node. (05 Mar 2000) |
| Rosenmuller's node | One of the deep inguinal lymph node's located in or adjacent to the femoral canal; sometimes mistaken for a femoral hernia when enlarged. Synonym: Rosenmuller's gland, Rosenmuller's node. (05 Mar 2000) |
| middle rectal lymph node | A lymph node along the middle rectal artery that receives afferents from the pararectal nodes and sends efferents to the internal iliac nodes. Synonym: middle rectal node, nodus rectalis medius. (05 Mar 2000) |
| middle rectal node | A lymph node along the middle rectal artery that receives afferents from the pararectal nodes and sends efferents to the internal iliac nodes. Synonym: middle rectal node, nodus rectalis medius. (05 Mar 2000) |
| mucocutaneous lymph node syndrome | <syndrome> An acute febrile illness in children first described in Japan in the late 1960's. Referred to as mucocutaneous lymph node syndrome because of typical changes in the mucus membranes that line the lips and mouth. Enlarged and tender lymph glands are also seen. Synonym:: Kawasaki disease. (13 Nov 1997) |
