山羊心脏二尖瓣复合体的应用解剖学研究

Applied Anatomic Study on Mitral Complex of Goat Heart

目的观测山羊心脏二尖瓣复合体的解剖结构,为比较解剖学积累资料。方法利用大体解剖方法观测山羊二尖瓣复合体的形态结构。结果山羊心脏二尖瓣复合体由二尖瓣瓣环、瓣膜、腱索和乳头肌构成,二尖瓣瓣环周长为47.00±7.39mm,前瓣的高度为7.93±2.03mm,宽度为21.58±4.17mm,后瓣的高度为9.89±1.90mm;宽度分别为20.61±4.22mm;前乳头肌起始点至前瓣、后瓣和后内侧连合的腱索条数分别为5.06±1.71,3.19±1.11,1.25±0.48;后乳头肌起始点附着于前瓣、后瓣和前外侧连合的腱索条数分别为4.50±1.88,4.16±1.84,1.32±0.54。结论山羊心脏二尖瓣复合体的结构与人类相似,但形态有特异性。

Objective To observe and measure the anatomical structure of mitral complex in goat to accumulate comparative data for zootomy. Method To observe the morphology and structure of mitral complex in goat and with gross anatomical method. Results The mitral complex of goat was composed of the mitral ring and valve, chordae tendinease and papillary muscles. The length of the mitral ring was 47.00±7.39 mm; the average height of anterior valves was 7.93±2.03 mm, the width of anterior valves was 21.58±4.17 mm; the average height of posterior valves was 9.89±1.90 mm, the width of posterior valves was 20.61±4.22 mm; the average numbers of chordae tendinease from anterior papillary muscle to anterior valve, posterior valve and posterior medial commissural area were 5.06±1.71, 3.19±1.11, 1.25±0.48; the average numbers of chordae tendinease from posterior papillary muscle to anterior valve, posterior valve and anterior lateral commissural area were 4.50±1.88, 4.16±1.84, 1.32±0.54. Conclusion The mitral complex of goat heart is similar to that of human heart in morphology and structure in spite of the differences in configuration and diathesis.
