| nodi lymphatici intercostales | One or two small nodes located posteriorly in each intercostal space; they receive lymph from the parietal pleura, intercostal space, and posterior body wall; the nodes in the upper spaces empty into the thoracic duct; the nodes in the lower spaces form a descending intercostal trunk that opens into the cisterna chyli. Synonym: nodi lymphatici intercostales. (05 Mar 2000) |

| bulbus venae jugularis | <anatomy, vein> One of two dilated parts of the internal jugular vein: the superior bulb (Heister's diverticulum) is a dilation at the beginning of the internal jugular vein in the jugular fossa of the temporal bone; the inferior bulb is a dilat ed portion of the vein just before it reaches the brachiocephalic vein. Synonym: jugular bulb, bulbus venae jugularis. (05 Mar 2000) |
| valvula venae cavae inferioris | An endocardial fold extending from the anterior inferior margin of the inferior vena cava to the anterior part of the limbus fossa ovalis. Synonym: valvula venae cavae inferioris, caval valve, eustachian valve, sylvian valve. (05 Mar 2000) |
