| disease, his | Named for the Swiss physician Wilhelm His, Jr. (who also described the bundle of His in the heart), this is a louse-borne disease first recognised in the trenches of World War I (and so called trench fever), again a major problem in the military in World War II, seen endemically in Mexico, N. Africa, E, Europe, and elsewhere. The cause, Rochalimaea quintana, is an unusual rickettsia that multiplies in the gut of the body louse. Transmission to people can occur by rubbing infected louse feces into abraded (scuffed) skin or conjunctiva (whites of the eyes). Onset of symptoms is sudden, with high fever, headache, back and leg pain and a fleeting rash. Recovery takes a month or more. Relapses are common. Also called Wolhynia fever, shin bone fever, quintan fever, five-day fever, Meuse fever, His-Werner disease, Werner-His disease. (12 Dec 1998) |
| disease, his-werner | Named for the Swiss physician Wilhelm His, Jr. (who also described the bundle of His in the heart) and the German physician Heinrich Werner (who did not describe Werner's syndrome). See Disease, His. (12 Dec 1998) |

| isthmus of His | A constriction in the embryonic neural tube delineating the mesencephalon from the rhombencephalon, the anterior portion of the rhombencephalon connecting with the mesencephalon. Synonym: isthmus rhombencephali, isthmus of His. (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.
