| Hoche's bundle | A compact bundle composed of descending branches of posterior root fibres located near the border between the fasciculi gracilis and cuneatus of the cervical and thoracic spinal cord; it corresponds to the septomarginal fasciculus, Hoche's tract, or oval area of Flechsig in the lumbar, and to the triangle of Philippe-Gombault in the sacral spinal segments; like these, it can be demonstrated only in cases of demyelination resulting from dorsal root lesions. Synonym: fasciculus semilunaris, fasciculus interfascicularis, comma bundle of Schultze, comma tract of Schultze, interfascicular fasciculus. (05 Mar 2000) |

| anterior ground bundle | The ground bundle of the anterior column of the spinal cord. See: fasciculi proprii. Synonym: anterior ground bundle. Origin: L. Dim. Of fascis, bundle (05 Mar 2000) |
| Arnold's bundle | A fibre group originating in the cerebral cortex of the temporal lobe, particularly the superior and middle temporal gyri, following the sublenticular limb of the internal capsule into the lateral margin of the crus cerebri in which it descends to its termination in the pontine nuclei or the ventral part of the pons. Synonym: tractus temporopontinus, Arnold's bundle, Arnold's tract. (05 Mar 2000) |
| atrioventricular bundle | The bundle of modified cardiac muscle fibres that begins at the atrioventricular node as the trunk of the atrioventricular bundle and passes through the right atrioventricular fibrous ring to the membranous part of the interventricular septum where the trunk divides into two branches, the right crus of the atrioventricular bundle and the left crus of the atrioventricular bundle; the two crura ramify in the subendocardium of their respective ventricles. Synonym: fasciculus atrioventricularis, atrioventricular band, Gaskell's bridge, His' band, His' bundle, bundle of His, Keith's bundle, Kent's bundle, Kent-His bundle, ventriculonector. (05 Mar 2000) |
| A-V bundle | The bundle of modified cardiac muscle fibres that begins at the atrioventricular node as the trunk of the atrioventricular bundle and passes through the right atrioventricular fibrous ring to the membranous part of the interventricular septum where the trunk divides into two branches, the right crus of the atrioventricular bundle and the left crus of the atrioventricular bundle; the two crura ramify in the subendocardium of their respective ventricles. Synonym: fasciculus atrioventricularis, atrioventricular band, Gaskell's bridge, His' band, His' bundle, bundle of His, Keith's bundle, Kent's bundle, Kent-His bundle, ventriculonector. (05 Mar 2000) |
| Bachmann's bundle | Division of the anterior internodal tract that continues into the left atrium providing a specialised path for interatrial conduction. (05 Mar 2000) |
| bundle | 1. To prepare for departure; to set off in a hurry or without ceremony. 2. To sleep on the same bed without undressing; applied to the custom of a man and woman, especially lovers, thus sleeping. "Van Corlear stopped occasionally in the villages to eat pumpkin pies, dance at country frolics, and bundle with the Yankee lasses." (W. Irving) Source: Websters Dictionary (01 Mar 1998) |
| bundle bone | Immature bone containing thick bundles of collagen fibres arranged nearly parallel to one another with osteocytes in between; a similar type of bone is found in regions penetrated by fibres of Sharpey, as at ligament and tendon attachments. (05 Mar 2000) |
| bundle-branch block | <cardiology, physiology> Abnormal conduction through one of the conductive branches which normally supply the right and left ventricles. Usually results in delayed conduction though either the right or left bundle branches where one ventricle is excited before the other because of absence of conduction in one of the branches of the bundle of His. Intraventricular block due to interruption of conduction in one of the two main branches of the bundle of His and manifested in the electrocardiogram by marked prolongation of the QRS complex; block of each branch has distinctive QRS morphology. (05 Mar 2000) |
| bundle divertor | <radiobiology> Divertor concept where a toroidal field coil extracts a bundle of toroidal field lines (flux) and forms a separatrix in the toroidal field. (Hard to do and tends to mess up axisymmetry of the torus, not used much.) (09 Oct 1997) |
| bundle of His | <cardiology, physiology> Small band of specialised cardiac muscle fibres that originates in the atrioventricular node and extends into the membranous part of the interventricular septum. (12 Dec 1998) |
| bundle of Rasmussen | A bundle of fibres that originates from the periolivary nuclei bilaterally, exits the brainstem on the vestibular nerve, joins the cochlear nerve in the inner ear, and terminates on outer hair cells. Synonym: bundle of Rasmussen, olivocochlear fibres. (05 Mar 2000) |
| Gantzer's accessory bundle | <anatomy> An accessory muscle extending from the superficial flexor of the digits to the deep flexor of the digits. (05 Mar 2000) |
| vascular bundle | Strand of vascular tissue in a plant, composed of xylem and phloem. (18 Nov 1997) |
