生物运动系统具有液晶结构。本文首先介绍了具有近晶液晶结构的横纹肌收缩系统。我们在这里报告了肌肉的自动振荡特性，称为自发振荡收缩（SPOC）[1]，并建立了一个数学模型来解释其机制[2，3]。此外，肌节动力学在心跳过程中观察到的描述。第二个主题是减数分裂纺锤体的微观力学，这是微管与染色体的双极组装[4]。第三个主题是证明在油包水液滴内自发形成的收缩肌动蛋白环，这可以被认为是人工细胞模型[5]。
Bio-motile systems have liquid-crystalline structures. This review first describes the contractile system of striated muscle having a smectic liquid crystalline structure. We here report the muscle's auto-oscillatory property named spontaneous oscillatory contraction (SPOC) [1], and a mathematical model to explain its mechanism [2, 3]. Also, sarcomere dynamics observed during heartbeat are described. The second topic is the micromechanics of the meiotic spindle, a bipolar assembly of microtubules with chromosomes [4]. The third topic is the demonstration of a contractile actin ring spontaneously formed inside a water-in-oil droplet, which can be considered as an artificial cell model [5].
