| haemal node | <anatomy> A lymphoid structure in which the blood sinuses are present in place of lymph sinuses; haemal node's occur in ruminants and some other mammals, but their presence in humans is questioned. Synonym: haemal gland, haemolymph gland, haemolymph node, vascular gland. (05 Mar 2000) |

| posterior tibial lymph node | A small inconstant lymph node located along the course of the posterior tibial artery. Synonym: nodus tibialis posterior, posterior tibial node. (05 Mar 2000) |

Synonym: haemal gland, haemolymph gland, haemolymph node, vascular gland. (05 Mar 2000) |
| cystic lymph node | A lymph node at the neck of the gallbladder draining lymph into the hepatic nodes. Synonym: nodus cysticus, cystic node. (05 Mar 2000) |
| cystic node | A lymph node at the neck of the gallbladder draining lymph into the hepatic nodes. Synonym: nodus cysticus, cystic node. (05 Mar 2000) |
| primitive node | A local thickening of the blastoderm at the cephalic end of the primitive streak of the embryo. Synonym: Hensen's knot, Hensen's node, Hubrecht's protochordal knot, primitive knot, protochordal knot. (05 Mar 2000) |
| S-A node | <anatomy, cardiology, physiology> The impulse generating (pacemaker) tissue located in the right atrium, under the epicardium at the upper end of the sulcus terminalis. The specialised cardiac muscle fibres generate cardiac impulses that normally acts as the pacemaker of the cardiac conduction system. Normal impulses start in the sinoatrial node and are transmitted to the ventricles, through the atrioventricular node and into the bundle of His. Synonym: nodus sinuatrialis, atrionector, Flack's node, Keith and Flack node, Keith's node, Koch's node, sinoatrial node, sinus node. (20 Jun 2000) |
| Hensen's node | A local thickening of the blastoderm at the cephalic end of the primitive streak of the embryo. Synonym: Hensen's knot, Hensen's node, Hubrecht's protochordal knot, primitive knot, protochordal knot. (05 Mar 2000) |
| schmorl node | <radiology> Chondrification defects where periosteal vessels penetrate cartilage plates of disc, Xray: concave defects at upper and lower vertebral endplates with sharp margins produced by herniation of disc material, MRI: similar signal intensity as disc, low signal intensity of rim, associated with narrow disc space Differential diagnosis: SHOOT, Scheuermann disease, hyperparathyroidism, osteoporosis, osteomalacia, trauma (12 Dec 1998) |
| hilum of lymph node | The depressed area of the surface of a lymph node through which the efferent lymphatics emerge from the medulla and through which blood vessels enter and leave the node. Synonym: hilum nodi lymphatici. (05 Mar 2000) |
| signal 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) |
