Parotid and Mandibular Salivary Glands Segmentation Of The One Humped Dromedary Camel (Camelus dromedarius)

The present study provides detailed anatomical description of the parotid and mandibular salivary glands of the one humped camel with their segmentation based on arterial blood supply and salivary ducts; to facilitate partial removal of the pathologic gland. The shape, position, relations and blood supply of both salivary glands with their ducts were studied on six cadaveric heads. The mandibular and parotid ducts were injected with Urographin® as contrast medium; through inserting the catheter into their openings in the oral cavity; then applying lateral radiography immediately after the injection. The common carotid arteries were injected with red Latex Neoprene and dissected. The parotid gland was irregular rectangular and had five processes while the mandibular gland was irregular triangular with rounded proximal and pointed distal extremity. The parotid duct enters the oral cavity on the cheek opposite the upper 4th molar tooth. The mandibular duct opens in the oral cavity at the sublingual caruncles on the sublingual floor, just about 2cm cranial to frenulum linguae. Both The parotid and the mandibular salivary glands could be divided into four segments. Partial removal of the pathologic parotid or mandibular salivary glands could be performed based on their segmentation. Tumor arrest could be established by ligation of the arterial supply of specific part of the gland.
