摘　　要：采用传统的系统形态解剖学方法对短蛸神经系统和消化系统进行观察,并描述、绘图。结果表明,短蛸中枢神经系统由围绕着食道的脑神经节、足神经节和脏神经节组成,周围神经系统可见口球神经节、视神经节、胃神经节、鳃神经节、外套神经节和脑神经索;短蛸的消化管从前到后包括口、口球、食道、嗉囊、胃、胃盲囊、肠、直肠、肛门,消化腺包括1个肝脏及前唾液腺、后唾液腺和胰脏各1对。The traditional morphological anatomical technique was applied to study the morphology of the nervous and digestive systems of Octopus ocellatus. The results showed that the central nervous system （CNS） of O. ocellatus consisted of dorsal cerebral ganglion, ventral tandem visceral and pedal ganglions around the esophagus. The buccal ganglion, optic ganglion, gastric ganglion, gill ganglion, stellate ganglion and brain cable could be seen in the peripheral nervous system. The digestive system of O. oceUatus included the digestive tract and the digestive gland. The digestive tract consisted of bulhus otis, esophagus, craw, stomach, stomachic caecus, intestines, rectum, anus. The digestive gland consisted of a pair of anterior salivary glands, posterior ones and hepatopancreas.
