The Anatomical and Morphometrical Investigations on the Cisternal and Canalicular Segments of the Hypoglossal Nerve in Holstein Cattle

Öz

Aim: The purpose of this study is determined that anatomical and morphometrical characteristics of cisternal
and canalicular part of the hypoglossal nerve in Holstein cattle. Material and Method : In this study, 24 heads of adult Holste in cattle which obtained from the slaughterhouse were used. Samples were fixated by using classical method and dissected in anatomy laboratory. Results: lt was seen that hypoglossal nerve as 46,04±7,29 roollets left from 10,36 ± 1,01 mm. in diameter hypoglossal line which placed 7,90 ± 0,54 mm in length from fissura mediana laterally onto level of the decussatio pyramidum in Holste in cattle. It was found out, at the end of cisternal course 9,23±1 ,50 in lenght, rootlets made up 7,90±1 ,75 bundles and these bundles penetrated into the dura mater via 2,29±0,68 points. Bundles which were surrounded by dura mater passed through 1,50±0,62 hypoglossal canals and then reached fossa condylaris ventralis. At this point these bundles were joined each others and composed of a nerve trunk. Conclusion: This study demonstrates comprehensively anatomical and morphometrical properties of cisternal and canalicular part of the hypoglossal nerve.
