Özet
The ethmoid bone is an unpaired and non-visible bone from the external aspect of the skull, situated between the cranial and nasal cavities, forming the rostral boundary between them. The lamina cribrosa is one of the components of the ethmoid bone, through which bundles of the olfactory nerve pass from the nasal cavity to the olfactory bulb of the forebrain. In most textbooks of veterinary anatomy and in the scientific literature to date, detailed information regarding the dimensions of the ethmoid fossa, its volume, and the exact number of cribriform foramina is lacking. In this study, five red fox skulls were examined. A detailed description of the ethmoid fossa was performed, and morphometric parameters of the skull, cranial cavity, and ethmoid fossa were measured using a digital caliper. Additionally, the volumes of the cranial cavity and the ethmoid fossa were determined, and the exact number of cribriform foramina was counted. The results showed that the mean volumes of the cranial cavity and the ethmoid fossa were 49.67 ± 3.42 cc and 1.84 ± 0.15 cc, respectively. The average number of cribriform foramina was 183 ± 28.1 per side (range: 139–216). Each side of the ethmoid fossa was divided into three parts by fine ridges running in a dorsolateral direction, and many foramina in the dorsolateral region opened into the frontal sinuses. In conclusion, this study provides new information on the detailed morphology of the ethmoid bone in wild carnivores such as the red fox, particularly regarding the number of cribriform foramina. These findings contribute to a better understanding of ethmoid bone morphology and may have implications for comparative cranial anatomy.
