Astronomical Instruments and Techniques,ved. In addition, bones serve as levers for muscles to contract against (Figure 5.2). Muscles typically operate at negative mechanical advantage (r/R < 1). This arrangement increases the range of motion over which muscles can operate effectively, but it also increases the muscle force needed to moveheadway 发表于 2025-3-27 15:43:13

Reduced Bone Formation in the Pathogenesis of Bone Fragility,ed and formed in each basic multicellular unit (BMU) on the endocortical surface determine the proximity of the endocortical and periosteal surfaces. This in turn determines the cortical thickness and the distance the cortical shell is placed from the neutral or long axis of the bone. This geometricTRUST 发表于 2025-3-28 07:55:17
