Abstract
A model of activation of muscle contraction has been proposed. It is based on calcium diffusion and binding to specific regulatory sites in a sarcomere. Calcium ions activate interactions of contractile proteins and thus the generation of force. The model quantifies the relation between calcium released from intracellular stores and the elicited force.
摘要
已经提出了一种肌肉收缩激活模型。它基于钙在肌节中的扩散以及与特定调节位点的结合。钙离子激活收缩蛋白的相互作用，从而产生力量。该模型量化了从细胞内储存释放的钙与所引发力量之间的关系。
