| Abstract | ||||
| The nasal cavity of the rabbit is supplied mainly by the sphenopalatine and the external ethmoidal arteries and partly by the malar artery, The sphenopalatine artery is one of the terminal branches of the des cending palatine artery. In the nasal cavity it divides into a larger A. nasalis caudalis and smaller A.nasalis lateralis et septalis. The caudal nasal artery supplies the rostral 2/3 of the dorsal nasal concha, ventral nasal concha, rostral part of the middle nasal concha, ethmoidal conchae and septum nasi, as well as the lateral nasal wall. The external ethmoidal artery is one of the terminal branches of the external ophthalmic artery. It supplies the caudal part of the dorsa! nasal concha, middle and ethmoidal conchae and the septum nasi, as well as the maxillary sinus. Blood is drained from the nasal cavity through the dorsal nasal vein, lateral nasal vein, major palatine vein, palatine veins and sphenopalatine venous plexuses in the nasal conchae and the vein. These veins form septum nasi. | ||||
