| Killian's bundle | Origin, outer surfaces of thyroid (thyropharyngeal part) and cricoid (cricopharyngeal part, musculus cricopharyngeus; superior or upper oesophageal sphincter muscle) cartilages; insertion, pharyngeal raphe in the posterior portion of wall of pharynx; action, narrows lower part of pharynx in swallowing, the cricopharyngeal part has a sphincteric function for the oesophagus, allowing some voluntary control of eructation and reflux; nerve supply, pharyngeal plexus. Synonym: musculus constrictor pharyngis inferior, cricopharyngeus muscle, laryngopharyngeus, musculus laryngopharyngeus. (05 Mar 2000) |

| pallister-killian syndrome | <syndrome> A condition with multiple malformations at birth and mental retardation due to isochromosome 12p mosaicism (an abnormal chromosome 12 in some cells). (12 Dec 1998) |

| Killian, Gustav | <person> German laryngologist, 1860-1921. See: Killian's bundle, Killian's operation, Killian's triangle. (05 Mar 2000) |
| Killian's operation | <procedure, surgery> An operation for frontal sinus disease in which the entire anterior wall is removed and the mucous membrane is curetted away. The ethmoid cells are scraped out through an opening in the nasal process of the maxillary bone, and the upper wall of the orbit is removed as well. (05 Mar 2000) |
| Killian's triangle | <anatomy> The triangular-shaped area of the cervical oesophagus bordered by the oblique fibres of the inferior constrictor muscle of the pharynx and the transverse fibres of the cricopharyngeus muscle through which Zenker's diverticulum occurs, and the A-V nodal triangle between the coronary sinus orifice and the ventricular crest. Synonym: laimer triangle. (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) |
