| Purpose of the study: to establish the morphological characteristics of the
nuclei of the cerebellum. The study was carried out on 340 specimens of the cerebellum of people who died at the age of 20 to 99 years due to diseases. In this study were used mac- ro-microscopic, morphometric, histological (hematoxylin-eosin, for Krutsay, by Pat. 65245 Ukraine [4]) methods of statistical analysis. Fastigial nucleus – paired formation, that located in the white matter of the cerebellar vermis left and right about his middle-sagittal line over the top of the fourth ventricle and spreads ventro-laterally from the base of the tongue of the cer- ebellum. In 55,9% (190 preparations), the kernel of the tent has a rounded shape, 28,5% (98 drugs) – conical, that faces by its base to the front. On histological preparations we noted the connection between the gray matter of the right and left nucleus of the tent as its thin bundle. In the ventral-lateral direction the nucleus of the tent connected to emboliform nucleus thin bundle of the grey matter, which originates from the anterior edge of the nucleus of the tent. In the dorsal-lateral di- rection the nucleus of the tent connected to emboliform nucleus by thin bundle of 90 the grey matter. The length of the nucleus from 3 to 6 mm, width – from 4 to 6 mm, the height – of 2 to 5 mm. Globose nucleus is paired formation, located in the right and the left hemi- sphere of the cerebellum ventrally from the anterioro edge of the emboliform nu- cleus and coated from the dorsal surface of the dentate nucleus. The nucleus ex- tends into ventro-lateral direction in the thickness of white matter of the gate of dentate nucleus, the shape changes from the winding tape-shaped to the sigmoid- oval, depending on its parts. The dorsal-medial part of the nucleus is connected to a thin bundle of the gray matter to the anterior-lateral part of the nucleus of the tent. In the ventral-lateral part the nucleus is connected by thin bundle of the gray matter with ventral-anterior part of the emboliform nucleus. The length of the nu- cleus from 2 to 6 mm, width – from 1 to 4 mm and height – from 2 to 5 mm. Emboliform nucleus – pair formation, located in the right and the left hemi- sphere of the cerebellum parallel to the sagittal plane and is separated from the cer- ebellar vermis by the thin bundle of white matter, it lies at the gates of the gear core, adjacent to the first gyrus dentate nucleus, which is connected with its dorso- medial surface of a thin and wide plate gray matter. The shape of the nucleus in 80% (272 of preparations) incorrect triangular with its apex facing in the ventral direction, 20% (68 of preparations) – quadrilateral elongated parallel to the sagittal plane of the cerebellar vermis. The length of the nucleus is from 4 to 11 mm, width – from 3 to 8 mm, the height – of 2 to 6 mm. The dentate nucleus is paired formation, located in the right and the left hemisphere of the cerebellum, which lies deep in their white matter and occupies their medial department. We found on the macro-microscopic preparations the nu- cleus has four gyrus in the gate area of the dentate nucleus on its ventral surface. The plate of grey matter of the dentate nucleus is divided into two sections: the dorsomedial, the first three gyrus are related to it, the fourth gyrus is related. Walk- ing toward the back of the cerebellar hemispheres 1-3 gyri dentate nucleus ventral are folded to form a loop, respectively, each gyrus. Fourth gyrus of the dentate nu- cleus is much shorter and wider than 1-3 gyri, its plate of grey matter has a small scroles in the form of wavy lines. The fibers going out from the front of the 1-3 gy- ri and have antero-dorsal direction and fibres going out from the base of the 4 gy- rus – in the anterior-ventral direction. The length of the nucleus is from 12 to 25 mm, width – from 9 to 21 mm, the height – from 6 to 20 mm. жүктеу/скачать 3,44 Mb. Достарыңызбен бөлісу:
