太行山猕猴寰椎桥的形态和分布
Morphological and distribution characteristics of the atlas bridges of the macaques Macaca mulatta from the Taihang mountains
摘要
Abstract
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.关键词
