This study aimed to determine the number of mental foramina (MFs) in vervet monkeys of the Cercopithecini tribe and perform a µCT analysis of mental foramina and mandibular canal morphology. A total of 19 simian skulls belonging to Chlorocebus aethiops species were used in the analyses. An average of three mental foramina was present in most individuals from the analyzed group. The Mann–Whitney test revealed no statistically significant difference between the number of foramina on the right- and left-hand side. Likewise, no statistically significant differences between the number of MFs across sexes were observed. Correlation coefficient values between mandibular length and the ipsilateral number of MF indicate a weak and statistically non-significant (p > 0.05) linear relationship. Volumetric reconstructions revealed the presence of a single periosteal sheathed mandibular canal terminated with four small mental foramina.

非洲绿猴 (Grivet) (Chlorocebus aethiops) 精神孔数量的变异性

本研究旨在确定 Cercopithecini 部落黑长尾猴的颏孔 (MF) 数量，并对颏孔和下颌管形态进行 μCT 分析。分析中总共使用了 19 个属于 Chlorocebus aethiops 物种的猿猴头骨。来自分析组的大多数人平均存在三个精神孔。Mann-Whitney 检验显示右侧和左侧的椎间孔数量在统计学上没有显着差异。同样，在不同性别的 MF 数量之间没有观察到统计学上的显着差异。下颌长度与同侧 MF 数之间的相关系数值表明弱且统计上不显着 (p > 0.05) 线性关系。
