Muscle architecture is an important component to typical musculoskeletal models. Previous studies of human muscle architecture have focused on a single joint, two adjacent joints, or an entire limb. To date, no study has presented muscle architecture for the upper and lower limbs of a single cadaver. Additionally, muscle architectural parameters from elderly cadavers are lacking, making it difficult to accurately model elderly populations. Therefore, the purpose of this study was to present muscle architecture of the upper and lower limbs of a 104 year old female cadaver. The major muscles of the upper and lower limbs were removed and the musculotendon mass, tendon mass, musculotendon length, tendon length, pennation angle, optimal fascicle length, physiological cross-sectional area, and tendon cross-sectional area were determined for each muscle. Data from this complete cadaver are presented in table format. The data from this study can be used to construct a musculoskeletal model of a specific individual who was ambulatory, something which has not been possible to date. This should increase the accuracy of the model output as the model will be representing a specific individual, not a synthesis of measurements from multiple individuals. Additionally, an elderly individual can be modeled which will provide insight into muscle function as we age.
肌肉结构是典型肌肉骨骼模型的重要组成部分。以往对人体肌肉结构的研究主要集中在单个关节、两个相邻关节或整个肢体上。迄今为止，尚无研究展示单个尸体上下肢的肌肉结构。此外，缺乏来自老年尸体的肌肉结构参数，这使得准确模拟老年人群变得困难。因此，本研究的目的是展示一名104岁女性尸体上下肢的肌肉结构。去除上下肢的主要肌肉，测定每块肌肉的肌-腱质量、腱质量、肌-腱长度、腱长度、羽状角、最佳肌束长度、生理横截面积和腱横截面积。本完整尸体的数据以表格形式呈现。本研究的数据可用于构建一个能行走的特定个体的肌肉骨骼模型，这在迄今为止是无法做到的。这应该会提高模型输出的准确性，因为该模型将代表一个特定个体，而不是多个个体测量值的综合。此外，可以对老年人进行建模，这将有助于深入了解随着年龄增长肌肉的功能。
