摘　　要：目的:观察太行山猕猴寰椎桥(腹桥、侧桥和背桥)的形态和分布特征,推测寰椎桥在非人灵长类动物可能出现的进化趋势,理解人类寰椎桥变异。方法:在太行山猕猴寰椎标本,观察每个寰椎上3种寰椎桥的形态学特征和出现率。采用IBM SPSS 26.0软件进行数据处理,采用非参数χ^(2)检验进行各种寰椎桥间出现率差异比较。结果:腹桥和背桥是太行山猕猴寰椎的稳定结构,出现率分别是100.0%和97.7%。侧桥结构基本稳定,出现率为83.1%。侧桥从缺失到完整的过渡类型,表现出多态特征。结论:猕猴寰椎桥的主要类型为原始的A型,与主要类型为D型的人类发生分离,猕猴寰椎上的3种寰椎桥是一种稳定的性状。Objective:To observe the morphological structure and distribution characteristics of the three kinds of atlas-axis bridges(ventral,lateral,and dorsal)in Macaca mulatta from the Taihang mountains,attempting to understand the variation of the atlas bridges observed in human,and speculating on the possible evolutionary trend of the bone bridges in non-human primates.Methods:Specimens of atlas vertebrae from Taihangshan macaques were studied.The morphological characteristics and occurrence rates of three types of atlas bridges on each atlas vertebra were observed.IBM SPSS 26.0 software was used for data processing,and nonparametric chi-square tests were used for analyzing the differences in inter-species occurrence rates of atlas-axis bridges.Results:The ventral bridge and dorsal bridge were stable structures of the atlas vertebrae in Taihang macaques,with incidence rates of 100.0%and 97.7%,respectively.The lateral bridge was basically stable,with an occurrence rate of 83.1%.The lateral bridge showed polymorphic characteristics as it transitioned from absent to complete.Conclusion:The main type of atlas bridge in rhesus monkey is the primitive type A,which is separated from the main type D in human.The three atlas bridges in rhesus monkey can be considered as a stable trait.
