The present study examined the morphometric properties of the forelimb, including the inertial properties of the body segments and the morphometric parameters of 21 muscles spanning the shoulder and/or elbow joints of six Macaca mulatta and three M. fascicularis. Five muscle parameters are presented: optimal fascicle length (L(0)(M)), tendon slack length (L(S)(T)), physiological cross-sectional area (PCSA), pennation angle (alpha(0)), and muscle mass (m). Linear regressions indicate that muscle mass, and to a lesser extent PCSA, correlated with total body weight. Segment mass, center-of-mass, and the moment of inertia of the upper arm, forearm, and hand are also presented. Our data indicate that for some segments, radius of gyration (rho) predicts segment moment of inertia better than linear regressions based on total body weight. Key differences between the monkey and human forelimb are highlighted.
本研究考察了恒河猴的前肢形态测量特性，包括身体各节段的惯性特性以及跨越六只恒河猴和三只食蟹猴肩和/或肘关节的21块肌肉的形态测量参数。给出了五个肌肉参数：最佳肌束长度（L(0)(M)）、肌腱松弛长度（L(S)(T)）、生理横截面积（PCSA）、羽状角（alpha(0)）和肌肉质量（m）。线性回归表明，肌肉质量以及在较小程度上的PCSA与总体重相关。还给出了上臂、前臂和手部的节段质量、质心和转动惯量。我们的数据表明，对于某些节段，回转半径（rho）比基于总体重的线性回归能更好地预测节段转动惯量。突出了猴子和人类前肢之间的关键差异。
