Macroanatomic investigations on (he innervation of the tongue in holstein cattle

Abstract

This study was carried out to investigate the origines, courses and innervation areas of the cranial nerves innervating the tongue in Holstein cattle. For this purpose, as a material, it was used the eight ol Holstein cattle ensured (rom Konya slaughterhouses. The materials were dissected after fixed In formaldehit solution 10%: It was detected that the involved nerves left the cranial cavity through the different opening after steming from the different regions ol the brain, then, ended by reaching the concerned innervation parts. The lingual nerve terminated in the rostral two thirds of the tongue. The chorda tympani joined to the lingual nerve after leaving the petrotympanic fissure. The glossopharyngeal nerve stemmed from the medulla oblongata, then, dispersed in the caudal one third of the tongue. The hypoglossal nerve scattered in the tongue muscles after arising from the medulla oblongata.
