摘要
目的 观测山羊心脏三尖瓣复合体形态特征 ,为心脏研究和比较解剖学积累资料。方法 1 0 %甲醛固定的山羊心脏 1 0 5例 ,解剖并观测三尖瓣复合体 ,保留隔缘肉柱和羊心腔特有结构。结果 山羊心脏三尖瓣复合体前瓣、后瓣 ,隔侧瓣的高度分别为 :8 4 3± 2 0 0mm、8 1 3± 1 90mm、7 6 8± 2 .1 0mm ;宽度分别为 :1 4 0 3± 3 1 6mm、1 4 35± 2 70mm、1 6 78± 3 4 6mm。前乳头肌腱索总条数为 :7 79± 1 72。后群乳头肌腱索条数为 :7 4 2± 2 1 7,后群乳头肌的个数为 2 36± 0 92。隔侧群乳头肌腱索总条数为 :1 0 4 2± 2 4 9,隔侧群乳头肌的个数为 4 0 5± 1 4 4。隔缘肉柱的长度为 9 5 3± 3 4 6mm。结论 山羊心脏三尖瓣复合体和人类心相似 。
Objective To observe and measure the tricuspid valve complex in goat to accumulate comparative data for further study. Methods 105 hearts of goat were fixed with 10% formaldehyde. The tricuspid valve complex were dissected, observed and measured with anatomical method.Results The average heights of anterior, posterior and septal valves of the tricuspid valve complex in goat were 8.43±2.00mm, 8.13±1.90mm,7.68±2.10mm respectively; and their average widths were 14.03±3.16mm, 14.35±2.70mm,16.78±3.46mm respectively. The average number of chordae tendinesses of anterior papillary muscle is 7.79±1.72. The average number of chordae tendinesses of posterior papillary muscle is 7.42±2.17, the number of posterior papillary muscle is 2.36±0.92. The average number of chordae tendinesses of septal papillary muscle is 10.42±2.49,the number od septal papillary muscle is 4.05±1.44. The length of septomarginal trabecula is 9.53±3.46mm.Conclusion The tricuspid valve complex of goat is similar to that of human heart in morphology and structure in spite of the special structure of goat heart.
