中国大鲵 meaning in Chinese
chinese giant salamander
Examples
- In order to enrich the content of the anatomy and histology about andrias davidianus , obtain new data about systematic position and blood circulation physiology and also provide reference for comparative anatomy and vertebrate evolution reseach , we studied the anatomy and histology about andrias davidianus by means of normal inject method , normal paraffin section method , microcopy system and digital camera
本研究主要采用常规血管注射法，常规石蜡切片法，以及光学显微照相系统和荧光显微数码照相系统对中国大鲵( andriasdavidianus )的循环系统进行了比较详细的解剖学观察研究，并对其心脏及血管进行了组织学研究。目的在于丰富中国大鲵解剖学和组织学的资料，为中国大鲵分类地位的探讨和血液循环生理研究提供解剖学依据，同时也为比较解剖学和脊椎动物的进化提供解剖学依据。 - Examination shows that the heart of andrias davidianus have three chamers - two atria and one ventride , the atria on the left of midline , the ventricle on the right of midline , and the atria are divided into two cavities by septum interatriale . there are four valvula semilunaris in conus arteriosus , but no spiral valve in conus arteriosus . the coronary artery is made by arterica carotis externa branches
研究结果表明,中国大鲵循环系统解剖学特点为： 1 .心脏：心房心室为左右排列，两心房前后排列，共有4对动脉弓，其中第二、三对动脉弓汇合成一条背主动脉；动脉圆锥基部与心室相接处有4个瓣膜，动脉圆锥内没有螺旋瓣，动脉圆锥与腹侧主动脉干之间有3个半月瓣；房间隔有穿孔；冠状动脉由颈外动脉的分支汇合而成。
