Abstract

Sexual dimorphism, adaptational and evolutionary trends to the morphophysiology of mastication can be interpreted from maxillofacial and mandibular anatomy of animals. We looked at these regions in camels from three geographical zones in Nigeria. We noticed an isolated case of bilateral longitudinal opening in the nasal bones. Our study also revealed that camels show variations in the morphological arrangement of the incisive, maxilla and nasal bones as well as in the eruption pattern of their first premolar. No geographical variation was seen in camels from the three locations in their palatal morphometrics, but in the nasals, the midline nasal length was longest in camels from Maiduguri and this was more significant than those from Kano. All quantitative nasal and palatal parameters were significantly lower in immature camels when compared with the respective adults. This work provided information on the maxillofacial and mandibular region of the camels that will aid morphophysiological, archeological and adaptational studies of this species.
