Plasma cells are often present and represent another subtype with the plasma cells containing IgM and IgA. (12 Dec 1998) |
| mastoid lymph nodes | Two or three nodes in the region of the mastoid process; they receive afferent lymphatic vessels from the scalp and auricle and send efferent vessels to the superior deep cervical nodes. Synonym: nodi lymphatici mastoidei, mastoid lymph nodes. (05 Mar 2000) |
| visceral lymph nodes | The lymph nodes draining the viscera of the abdomen or of the pelvis. Synonym: nodi viscerales, visceral nodes. (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) |
| pectoral group of axillary lymph nodes | Lymph nodes located along the lateral thoracic vein; they receive the drainage of the pectoral region, including most of the drainage of the breast. Synonym: nodi lymphatici axillaris pectorales, anterior group of axillary lymph nodes. (05 Mar 2000) |
| central group of axillary lymph nodes | Nodes located around the midportion of the axillary vein; they receive afferent vessels from the lateral (brachial), pectoral, and subscapular groups of axillary nodes and send efferent vessels to the apical group of axillary node's. (05 Mar 2000) |
| gluteal lymph nodes | Nodes of the internal iliac group; they are subdivided into two groups: interior gluteal lymph nodes, located along the inferior gluteal vein; superior gluteal lymph nodes located along the superior gluteal vein. Synonym: nodi lymphatici gluteales. (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) |
| central mesenteric lymph nodes | The mesenteric lymph nodes located along the intestinal (jejunal and ileal) branches of the superior mesenteric artery. Synonym: nodi lymphatici superiores centrales, central mesenteric lymph nodes. (05 Mar 2000) |
| retroauricular lymph nodes | Two or three nodes in the region of the mastoid process; they receive afferent lymphatic vessels from the scalp and auricle and send efferent vessels to the superior deep cervical nodes. Synonym: nodi lymphatici mastoidei, mastoid lymph nodes. (05 Mar 2000) |
| retrocaecal lymph nodes | Nodes located behind the caecum draining lymph into the ileocolic nodes. Synonym: nodi lymphatici retrocaecales. (05 Mar 2000) |
| retropharyngeal lymph nodes | The three groups of lymph nodes, one median and two lateral, located between the pharynx and the prevertebral fascia; they receive lymph from the nasopharynx, the auditory tube, and the atlanto-occipital and atlantoaxial joints. Synonym: nodi lymphatici retropharyngeales. (05 Mar 2000) |
| retropyloric lymph nodes | A group of lymph nodes located behind the pylorus. Synonym: nodi retropylorici, retropyloric nodes. (05 Mar 2000) |
| mesenteric lymph nodes | Nodes located in the mesentery; they are of three classes: mesenteric lymph nodes, juxta-intestinal lymph nodes, and the superior middle group of mesenteric lymph nodes. Synonym: nodi lymphatici mesenterici. (05 Mar 2000) |
