| gyrus dentatus | Serrated strip of gray matter under the medial border of the hippocampus and in its depths. It is an archicortex which develops along the edge of the hippocampal fissure and which consists of molecular, granular, and polymorphic layers. The molecular layer is continuous with that of the hippocampus in the depths of the hippocampal fissure. (carpenter and sutin, human neuroanatomy, 8th ed, p626) (12 Dec 1998) |

| Stephanurus dentatus | The kidney worm or lard worm of swine, a strongyle nematode parasite species that also occurs, though rarely, in the liver of cattle. Adult worms in swine live in the perirenal fat, the kidney pelvis, or as erratic forms in many other locations. Eggs are passed through the urine and infection is direct, by ingestion of infective larvae or by skin infection, or indirect, by ingestion of earthworms in which the larvae can survive. Origin: G. Stephanos, crown, + oura, tail (05 Mar 2000) |
| nucleus dentatus cerebelli | The most lateral and largest of the cerebellar nuclei; it receives the axons of the Purkinje cells of the neocerebellum (lateral areas of cerebellar cortex); together with the more medially located globosus and emboliform nuclei it is the major source of fibres composing the massive superior cerebellar peduncle or brachium conjunctivum. Synonym: nucleus dentatus cerebelli, corpus dentatum, dentatum. (05 Mar 2000) |
| adjustable articulator | An articulator which may be adjusted to permit movement of the casts into recorded eccentric relationships, an articulator capable of adjustment to more than one eccentric position. (05 Mar 2000) |
| arcon articulator | An articulator with the equivalent condylar guides fixed to the upper member and the hinge axis to the lower member, an instrument that maintains a constant relationship between the occlusal plane and the arcon guides at any position of the upper member, thereby making possible more accurate reproductions of mandibular movements. (05 Mar 2000) |
| articulator | <dentistry> A special holder for models of your teeth. The articulator holds the models in the same alignment as your jaw so the orthodontist can look carefully at your bite. (08 Jan 1998) |
| non-arcon articulator | An articulator with the equivalent condylar guides attached to the lower member and the hinge axis to the upper member. (05 Mar 2000) |
