Vasculature and Innervation of The Inner Ear of Camel (Camelus Dromedarius)

Abstract

The osseous labyrinth, the arterial blood supply and innervation of the inner ear especially the cochlea of the camel were examined both macroscopically and microscopically using different techniques. The aim of this study to observe any variation between the osseous labyrinth of the camel and its arterial blood supply and innervation and the other mammals. The results of this study show variation between the camel and the other domestic animals in the course of the main arterial blood vessel, which supply the inner ear; caudal cerebellar artery. Also the angle of vestibulocochlear nerve and facial nerve at internal acoustic meatus is recorded. The cochlear artery and nerve show type of modification in the modulus of the cochlea, which influences in the morphology of the cochlea and consequently in physiological function.
