Abstract

In the present study, cadaver heads of 10 mongrel dogs utilised for student training in the Mehmet Akif Ersoy University Faculty of Veterinary Medicine Department of Anatomy Laboratory was used for macroanatomical examination of nasal cavity (cavum nasi) and innervation of this region. With the help of an electrical sawmill machine, cadaver heads were separated sagittally into two halves on the right side of the median line in order to avoid damage to the septum nasi. Left head halves were dissected and data were obtained. Measurements were made for concha nasalis dorsalis, concha nasalis media and concha nasalis ventralis in all materials. The mean and standard deviations of these measurements were calculated. It was found the nerves that are innervating the cavum nasi are nn. olfactorii, n. vomeronasalis, n. ethmoidalis and n. nasalis caudalis which were separated from n. ophtalmicus and n. maxillaris which are the branches of n. trigeminus. It was found that nerve fibres and n. vomeronasalis enter into the cavum nasi via foramina cribrosa. It was detected that n. ethmoidalis enters into the cavum cranii via foramen ethmoidale after leaving n. ciliaris and then runs dorsally and enters into the nasal cavity through foramina cribrosa. It was seen that n. nasalis caudalis enters into the nasal cavity through the foramen sphenopalatinum after leaving n. pterygopalatinus, a branch of n. maxillaris
