摘要

目的分析河南淅川下王岗人群下颌骨与咀嚼肌发达程度相关的形态特点，并探讨时代变异。方法对44例下王岗人群下颌骨的下颌角外翻、咬肌粗隆、翼肌粗隆、颏棘的表现特点进行记录，并与全新世其他人群进行对比分析。结果下王岗人群下颌角外翻、咬肌粗隆、右侧翼肌粗隆、颏棘主要表现为“显著”级别，与全新世对比人群有明显差异。结论下王岗人群与咀嚼肌肉相关的下颌骨性状主要表现为显著级别，可能反映其咀嚼肌肉比较发达，同时提示这些性状的表现程度随时代发生着变化。

Abstract

Objective To understand the variation of some mandibular traits related to masticatory muscle of Xiawanggang population in Xichuan county, Henan province. Methods This study was conducted on 44 human mandibles of Xiawanggang population. Mandibular trait is divided into several types, which consist of extroversion of mandibular angle, tuberositas masseterica, tuberositas ptelygoidea and mental spine. And then comparisons are made among different time periods during the Holocene. Results Extroversion of mandibular angle, tuberositas masseterica, right tuberositas ptelygoidea and mental spine turn out mainly to be “obvious” type among Xiawanggang population. Conclusion The mandibular traits of Xiawanggang population related to masticatory muscle is mainly " obvious " type, which may reflect their big musculus masseter. Meanwhile it is suggested that the degree of those traits varies as time period goes by in Holocene.
