| 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.

| 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.

| 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 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) |
