A macroscopical investigation on the tongue nerves in the van cat

Abstract

This study was performed lo determine the cranial nerves stimulating the tongue in the Van cat. For this purpose. adull four female and four male cats were used. Innervation of the tongue was derived from the lingual, glossopharyngeal. hypoglossal nerves and the cord ol the tympanum. The lingual nerve sprang from the mandibular nerve along with the alveolar inferior nerve. The lingual nerve received Ihe cord ol the tympanum after coursing 0,5 cm in the medial pterygoid muscle, and supplied the cranial two-third of the tongue. The glossopharyngeal nerve arose from the medulla oblongata into three and four trunks, and terminated at the caudal third of the tongue after leaving the cranial cavity through the jugular foramen along wilh the vagus and accessory nerves. The hypoglossal nerve diffused the muscles of the tongue by coursing together with the lingual artery after leaving the cranial cavity from the hypoglossal canal. The digastric and stylohyoid branches originating Irom the facial nerve ran the digastnc and stylohyoid muscles, respectively.
