| RLNL | regional lymph node lymphocytes |

| RLND | retroperitoneal lymph node dissection |
| sigmoid arteries | Origin, inferior mesenteric; distribution, descending colon and sigmoid flexure; anastomoses, left colic, superior rectal. Synonym: arteriae sigmoideae. (05 Mar 2000) |
|---|---|
| sigmoid colon | <anatomy> The portion of the colon that connects to the descending colon above and the rectum below. (27 Sep 1997) |
| sigmoid flexure | <anatomy> The portion of the colon that connects to the descending colon above and the rectum below. (27 Sep 1997) |
| sigmoid fossa | A broad groove in the posterior cranial fossa, first situated on the lateral portion of the occipital bone, then curving around the jugular process on to the mastoid portion of the temporal bone, and finally turning sharply on the posterior inferior angle of the parietal bone and becoming continuous with the transverse groove; it lodges the transverse sinus. Synonym: sulcus sinus sigmoidei, sigmoid fossa, sigmoid groove, sigmoid sulcus. (05 Mar 2000) |
| sigmoid groove | A broad groove in the posterior cranial fossa, first situated on the lateral portion of the occipital bone, then curving around the jugular process on to the mastoid portion of the temporal bone, and finally turning sharply on the posterior inferior angle of the parietal bone and becoming continuous with the transverse groove; it lodges the transverse sinus. Synonym: sulcus sinus sigmoidei, sigmoid fossa, sigmoid groove, sigmoid sulcus. (05 Mar 2000) |
| sigmoid kidney | Upper pole of one kidney fused with the lower pole of the other. (05 Mar 2000) |
| sigmoid notch | The deep notch between the condylar and coronoid processes of the mandible. Synonym: incisura mandibulae, sigmoid notch. (05 Mar 2000) |
| sigmoid sinus | The S-shaped dural venous sinus lying deep to the mastoid process of the temporal bone and immediately posterior to the petrous temporal bone; it is continuous with the transverse sinus and empties into the internal jugular vein as it passes through the jugular foramen. Synonym: sinus sigmoideus. (05 Mar 2000) |
| sigmoid sulcus | A broad groove in the posterior cranial fossa, first situated on the lateral portion of the occipital bone, then curving around the jugular process on to the mastoid portion of the temporal bone, and finally turning sharply on the posterior inferior angle of the parietal bone and becoming continuous with the transverse groove; it lodges the transverse sinus. Synonym: sulcus sinus sigmoidei, sigmoid fossa, sigmoid groove, sigmoid sulcus. (05 Mar 2000) |
| sigmoid veins | The several tributaries of the inferior mesenteric vein that drain the sigmoid colon. Synonym: venae sigmoideae. (05 Mar 2000) |
| sigmoid volvulus | Relatively common location of volvulus, with obstruction either proximal or distal to the sigmoid segment. (05 Mar 2000) |
| Babes' nodes | Collections of lymphocytes in the central nervous system found in rabies. (05 Mar 2000) |
| big axillary nodes and normal breasts | <radiology> Consider: lymphoma, leukaemia, rheumatoid arthritis (12 Dec 1998) |
| ranvier's nodes | Regularly spaced gaps in the myelin sheaths of peripheral axons. Ranvier's nodes allow saltatory conduction, that is, jumping of impulses from node to node, which is faster and more energetically favourable than continuous conduction. (12 Dec 1998) |
| mandibular nodes | 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) |
