(boom’kéz) (Oswald Conrad Edward Bumke, German neurologist, born 1877]. See Inflated or blad- pupil. bunch (buntsh). horses. bundle (bun’dl).

Clarke's b., a bundle of nerve-fibers extending between Clarke's and Burdach’s columns. b. of Forel, a large bundle of fibers which arises from the nucleus ruber and its capsule, and runs upward, laterad, and dorsad to the ventral part of the thalamus, to the reticular layer, etc. Gierke’s res) iratory b., the solitary fasciculus. Gratiolet’s b., a bundle of nerve-fibers pa ing from the optic thalamus to the optic center in the occipital lobe of the brain. ground-b., anterior, that portion of the lateral tract of the spinal cord which lies between Tiirck’s column and the anterior root-fibers. ground-b., lateral, that part of the lateral column which is situated between the sides of the gray matter and the horns. b. of Helweg, a small triangular group of descending fibers of the anterolateral column of the cord, beginning in the neighborhood of the olive and pa ing down the cervical cord. b. of His, a muscular band, containing nerve-fibers, connecting the auricles with the ventricles of the heart. It serves to convey stimuli from the auricle to the ventricle. Degeneration of this bundle produces heart-block. The bundle of His is made up of four portions: the auriculoventricular node; the main bundle; the septal divisions, right and left; the terminal division, which sometimes takes the form of small moderator bands. Called also atrioventricular b., auriculoventricular b., a-v. b., and Gaskill’s bridge. Hoeve’sb.

Lenho ék’s b., the ascending root of the pneumogastric and glo opharyngeal nerves. main b., the portion of the bundle of His between the auriculoventricular node and the septal divisions. See. of His. Marchi’s b., a bundle of fibers on the anterior white column of the spinal cord from the cerebellum to the anterior gray column. marginal b., the white matter at the tip of the dorsal cornu of the spinal cord. Meynert’s b. See Meynert's fasciculus, under fasciculus. Monakow’s b. Sce prepvramidal tract, under tract. mauscle-b., a fascicle of muscle-fibers inclosed in a sheath. oral b., a projection which marks the outer surface of the dorsal zone of the human embryo. respiratory b., the solitary fasciculus.

Thorel’s b., a bundle of muscle-fbers in the heart connecting the sino-auricular and the auriculoventricular nodes, and pa ing around the mouth of the inferior vena cava. "s b., a bundle of nerve-fibers running from the cerebral cortex through the outer part of the crusta of the cerebral peduncle and the bone into the internal geniculate body. b. of Vicq d’- Azyr, a bundle of white fibers around the base of the anterior nucleus of the optic thalamus. Wei mann’s b., the bundle of striped muscular fibers of a neuromuscular spindle.
