| pancreatic lymph nodes | Nodes draining the body and tail of the pancreas; they are subdivided into two groups: inferior pancreatic lymph nodes (nodi lymphatici pancreatici inferiores ), located along the inferior pancreatic artery; superior pancreatic lymph nodes (nodi lymphatici pancreatici superiores ), located along the splenic artery near the origin of its pancreatic branches. Synonym: nodi lymphatici pancreatici. (05 Mar 2000) |

| pancreaticoduodenal lymph nodes | Nodes along the superior and inferior pancreaticoduodenal arteries. Synonym: nodi lymphatici pancreaticoduodenales. (05 Mar 2000) |
| pancreaticosplenic lymph nodes | Lymph nodes of the pancreatic tail and spleen, receiving afferents from both organs plus the greater curvature of the stomach; they drain to the coeliac lymph nodes. Synonym: nodi lymphatici pancreticolienales. (05 Mar 2000) |
| gastroduodenal lymph nodes | Group of nodes surrounding the pylorus, draining lymph into the right gastric or the right gastro-omental lymph nodes; it is divided into three smaller groups: suprapyloric lymph nodes, above the pylorus; subpyloric lymph nodes, below the pylorus; and retropyloric lymph nodes, behind the pylorus. Synonym: nodi lymphatici pylorici, gastroduodenal lymph nodes. (05 Mar 2000) |
| paramammary lymph nodes | Several lymph nodes on the lateral side of the mammary gland that receive afferents from the mammary gland and send efferents to the axillary pectoral group of lymph nodes. The paramammary lymph nodes are commonly considered as part of the pectoral group of axillary nodes. Synonym: nodi lymphatici paramammarii. (05 Mar 2000) |
| pararectal lymph nodes | Nodes located on either side of the rectum; they send efferents to the middle rectal and superior rectal nodes. Synonym: nodi lymphatici pararectales, nodi lymphatici anorectales, anorectal lymph nodes. (05 Mar 2000) |
| parasternal lymph nodes | A number of small nodes that lie along the course of the internal thoracic vessels; lymph enters these nodes from the anterior intercostal spaces, pericardium, diaphragm, liver and medial mammary gland; the efferent vessels pass upward to join the bronchomediastinal trunk of the same side. Synonym: nodi lymphatici parasternales. (05 Mar 2000) |
| parauterine lymph nodes | Nodes on either side of the uterus draining lymph to the internal iliac nodes and to the lumbar nodes via lymphatic vessels following the ovarian arteries. Synonym: nodi lymphatici parauterini. (05 Mar 2000) |
| paravaginal lymph nodes | Lymph nodes in association with the vagina; they drain to the internal iliac nodes. Synonym: nodi lymphatici paravaginales. (05 Mar 2000) |
| paravesical lymph nodes | The lymph nodes located around the urinary bladder and, in the male, the prostate; there are three groups: prevesicular lymph nodes, in front of the bladder; lateral vesical lymph nodes, on the right and left sides; postvesicular lymph nodes behind the bladder. (05 Mar 2000) |
| parietal lymph nodes | The lymph nodes draining the walls of the abdomen or of the pelvis. Synonym: nodi lymphatici parietales, parietal nodes. (05 Mar 2000) |
| 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) |
| 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) |
