“…However, Moustafa and Kamel () in camel reported the excavation of the frontal sinus extends beyond the angle of divergence of the external parietal crest. In agreement with Ahmed et al () in camel and Kumar and Dhingra () and Alsafy et al () in buffalo, the present study found a short curved supraorbital canal, which passes through the caudal frontal sinus.…”

“…Cattle and buffalo also have a nuchal and cornual diverticulum that extends into the frontal sinus (Alsafy et al, ; Budras et al, ; Nickel et al, ). The frontal sinus boundaries are limited to the frontal bone and Ahmed et al () have reported similar observations in camel. However, Moustafa and Kamel () in camel reported the excavation of the frontal sinus extends beyond the angle of divergence of the external parietal crest.…”

“…The paranasal sinuses were the frontal, maxillary, sphenoidal, ethmoidal, and lacrimal sinuses. These are different than that in cattle and buffalo which have frontal, maxillary, sphenoidal, ethmoidal, lacrimal and palatine sinuses (Ahmed et al, ; Alsafy et al, ; Bai et al, ; Budras et al, ; Dyce et al, ; Nickel et al, ; Saber, ).…”

“…The maxillary sinus appeared in a small excavation of the maxilla and the rostral part of zygomatic bone (Ahmed et al, ; Alsafy et al, ; Moustafa and Kamel, ; Saber, ). In addition, the sphenoidal sinus was in an excavation of the body and wing of the sphenoid bone and was subdivided into small compartments by bony plates.…”

Computed tomography (CT) is widely applied in human and veterinary medicine for investigation of a variety of diseases (Pollard and Puchalski, ).…”

The current study aimed to document by computed tomography (CT) the anatomical structures of the one-Humped camel head relative to their adaptability to living environments. Seven adult one-Humped camels' heads were used in this study. The structures of the nasal cavity, paranasal sinuses, oral cavity, orbit, and cranium were investigated using computed tomographic scans, cross, and sagittal sections of the head cadavers, and skulls. The study showed the nasal conchae had special properties where the dorsal nasal concha contained the dorsal conchal sinus, the middle nasal concha contained the middle conchal sinus, while the ventral nasal concha did not contain a sinus. The middle nasal concha was large and extended rostral between the dorsal and ventral nasal concha. The nasal meatuses were narrow spaces that suggested adaptability to a desert environment. The paranasal sinuses comprised maxillary, frontal, sphenoidal, lacrimal, and ethmoidal that were identified and labeled according to cheek teeth landmarks. The topographic description and relationship between nasal, oral, orbital, cranial cavities, pharynx, larynx, and paranasal sinuses were demonstrated. The articular disc, articular surface, and joint capsule of the temporomandibular joint were described by CT and cross sectional images. The current CT, cross, and sagittal sections images provide a reference for normal camel head anatomy. Anat Rec,

The current study was designed to describe the nasal turbinates of 15 heads of Anatolian shepherd dogs using the histology and scanning electron microscope. The caudal part of the nasal cavity is almost occupied by the ethmoidal concha that is related to the high dog's smelling. Keratinized stratified squamous epithelial lining of the rostral part of dorsal and ventral concha were interdigitated with the underlying lamina propria, with numerous sebaceous and sweat glands. The pseudostratified squamous epithelium lining of the middle part of the dorsal and ventral conchae had simple seromucous glands. The caudal third of dorsal, ventral, and ethmoidal conchae covered by olfactory epithelium that had three cell types; basal, supporting, and bipolar cells with mucous glands. SEM of the vestibular region shows that the dorsal conchae had a wrinkled surface with microvilli, little olfactory buds, and small sebaceous and sweat glands openings, while the ventral conchae had a lot of filiform‐like microvilli. SEM of the respiratory region shows that the dorsal conchae had a little number of seromucous glands and a rosette‐shape cilia, while the ventral conchae had numerous cellular cilia that cover all surface. SEM of the fundus region shows that the dorsal conchae had numerous microvilli of ciliated olfactory cells, while the ventral conchae had numerous long microvilli of ciliated olfactory cells. SEM of the ethmoidal nasal conchae shows a dense network of long microvilli of ciliated olfactory cells. We concluded that the morphological features of the dog's nasal turbinates were correlated with their environmental condition.

In order to improve the current knowledge of the topography and the anatomy of the paranasal sinuses of the one‐humped dromedary (Camelus dromedarius), we applied both conventional and advanced imaging techniques, namely, radiography and computed tomography (CT). Twelve heads of healthy dromedaries were used; eight heads were dissected to obtain skulls for the fenestration of the sinuses, two heads underwent anatomical sections, and two heads were imaged respectively by radiography and CT. Sinus fenestration allowed observation of sinuses and their communications. In each dissected dromedary's head, the frontal sinus is a large compartment delimited by thick partitions. The sphenoid sinus is divided into small compartments by bony plates. The lacrimal sinus occupies a small cavity in the rostro‐medial lacrimal bone of the orbit. In all dissected heads, there was neither palatal sinus nor ventral conchal sinus. Five images obtained by CT were selected with an excellent correspondence with the anatomical sections. These images allowed a good differentiation between bones and sinus cavities. The visualisation of the sinus cavities and their anatomical limits has better quality using the CT compared to the radiography. Radiographic and CT images are therefore very useful for the interpretation of clinical imaging studies of the dromedary's paranasal sinuses.
