摘　　要：目的观测家兔心脏二尖瓣复合体的解剖结构,为家兔心脏的研究和比较解剖学积累资料。方法取甲醛固定后的兔心50例,大体解剖并观测二尖瓣复合体。结果家兔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(23.46±4.34)mm;内侧瓣、外侧瓣、前外侧连合、后内侧连合的高度分别为(4.47±0.77)、(3.39±0.72)、(2.89±0.86)和(2.96±0.79)mm;内侧瓣、外侧瓣的宽度为(6.13±1.14)、(7.26±1.55)mm;前群乳头肌起始点至内侧瓣、外侧瓣、后内侧连合的腱索分别有(2.04±0.78)、(2.72±0.97)、(1.28±0.67)条;后群乳头肌起始点至内侧瓣、外侧瓣、前外侧连合的腱索分别有(2.00±0.86)、(2.24±0.77)、(1.32±0.74)条。结论家兔心脏二尖瓣复合体与人类二尖瓣复合体整体相比较小,但其结构与人类具有一定相似性,仅在形态数目有特异性。Objective To observe and measure the anatomical structure of mitral complex in rabbit,in order to accumulate comparative data for zootomy study. Methods Fifty hearts of rabbit was fixed with formaldehyde,the morphology and structure of mitral complex was observe with gross anatomical method. Results The mitral complex of rabbit was composed of the mitral ring and valve,chordae tendineae and papillary muscles. The average length of the mitral ring was（ 23. 46 ±4. 34） mm; the average height of medial valve,lateral valve,anterolateral commissure,posteromedial commissure was（ 4. 47 ±0. 77）,（ 3. 39 ± 0. 72）,（ 2. 89 ± 0. 86）,（ 2. 96 ± 0. 79） mm; the average width of medial valve,lateral valve was（ 6. 13 ±1. 14）,（ 7. 26 ± 1. 55） mm; the average number of chordae tendineae from anterior papillary muscle to medial valve,lateral valve and posteromedial commissure was 2. 04 ± 0. 78,2. 72 ± 0. 97,1. 28 ± 0. 67; the average number of chordae tendineae from anterior papillary muscle to medial valve,lateral valve and anterolateral commissure was 2. 00 ± 0. 86,2. 24 ± 0. 77,1. 32 ± 0. 74. Conclusion The mitral complex of rabbit heart is smaller than that of human heart. But he mitral complex of rabbit heart is similar to that of human heart in morphology and structure,in spite of the differences in the number of configuration.
