| dentate nucleus of cerebellum | 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) |
| dentate suture | One whose opposing margins present deep sawlike indentations, as most of the sagittal suture. Synonym: sutura serrata, dentate suture. (05 Mar 2000) |
| dentate-ciliate | <botany> Having the margin dentate and also ciliate or fringed with hairs. Source: Websters Dictionary (01 Mar 1998) |
| dentate-sinuate | <botany> Having a form intermediate between dentate and sinuate. Source: Websters Dictionary (01 Mar 1998) |
| dentatectomy | Surgical destruction of the dentate nucleus of the cerebellum. Origin: dentate (nucleus) + G. Ectome, excision (05 Mar 2000) |
| dentated | 1. <botany> Toothed; especially, with the teeth projecting straight out, not pointed either forward or backward; as, a dentate leaf. 2. <zoology> Having teeth or toothlike points. Origin: L. Dentatus, fr. Dens, dentis, tooth. Source: Websters Dictionary (01 Mar 1998) |
| dentatorubral cerebellar atrophy with polymyoclonus | A familial disorder beginning in late childhood, characterised by progressive cerebellar ataxia, action myoclonus and preserved intellect. Probably due to multiple causes, mitochondrial abnormalities being one. Synonym: dentatorubral cerebellar atrophy with polymyoclonus. (05 Mar 2000) |
| dentatorubral fibres | Nerve fibres arising in the dentate nucleus of the cerebellum and projecting, via the superior cerebellar peduncle and its decussation, to the contralateral red nucleus of the midbrain. Synonym: fibrae dentatorubrales. (05 Mar 2000) |
| dentatothalamic fibres | Nerve fibres projecting from the dentate nucleus of the cerebellum to the contralateral thalamus via the superior cerebellar peduncle (and its decussation); enter the thalamus as one component of the thalamic fasciculus. (05 Mar 2000) |
| dentatothalamic tract | That component of the superior cerebellar peduncle (brachium conjunctivum) which originates in the cerebellar nuclei, crosses completely in the decussation of the brachia conjunctiva, bypasses the red nucleus, and terminates in parts of the ventral anterior, ventral intermediate, ventral posterolateral, and central lateral nuclei of the thalamus. Synonym: tractus cerebellothalamicus, dentatothalamic tract. (05 Mar 2000) |
| dentatum | Synonym: dentate nucleus of cerebellum. Origin: L. Neut. Of dentatus, toothed (05 Mar 2000) |
