Morphological Observation of Digestive System of Aegypius Monachus
Abstract:The observation morphological constructure of digestive system of Aegypius monachus has been carried out by naked eyes and OLYMPUS dissection microscope in this paper.It shows:(1)This kind of bird has many bomblike papillas which point towards hind section in roof of cavum oris and root of tongue and pharynx.The papillas at the end of two branches of tongue root become stick like.These papillas can prevent the escaping of food;(2)Cinereous vulture has developed ingluvies;(3)Cinereous vulture has less developed pars muscularis ventriculi with wall less than 10mm in width,and there is cutinlike membrane on the internal surface while densitive flashing tendon mircle external. The intestine is very much developed but the interstinum caesum is very degenerate and hardly seen.According to the comparison between Cinereous vulture and some other birds,the carnivorous birds have very developed intestine and undeveloped caesum,but herbivorous birds have mild developed intestine and very developed caesun.
Keywords:Aegypius monachus  digestive system  morphology
