Ophiura Amphipholis kochii Lütken can move with any one of five arms directed forwards; therefore, each arm performs various functions during locomotion. The arm amputated together with the adjoining part of the central nervous ring is capable of complicated behaviour, particularly, of locomotion. Transection of the central nervous ring results in disturbances of the arms coordination. Experiments with amputation of a part of the arms showed that afferent signals from arms are important for determination of the leading arm and mode of locomotion. The experimental data suggest that each arm has an autonomous nervous centre, and coordinated activity of all arms is acheaved by an interaction of the nervous centres. The interaction results in function distribution among the arms and in synchronization of arm movements. The leading arm prevails, since the influences exerting by its centre determine activity of adjacent centres.
蛇尾纲的多棘海盘车（Ophiura Amphipholis kochii Lütken）可以将五条臂中的任意一条向前移动；因此，每条臂在运动过程中都执行各种功能。与中枢神经环相邻部分一起被切断的臂能够表现出复杂行为，特别是运动行为。中枢神经环的横断会导致臂的协调出现障碍。对部分臂进行截肢的实验表明，来自臂的传入信号对于确定主导臂和运动方式很重要。实验数据表明，每条臂都有一个自主神经中枢，所有臂的协调活动是通过神经中枢之间的相互作用实现的。这种相互作用导致臂之间的功能分配以及臂运动的同步。主导臂占优势，因为其神经中枢施加的影响决定了相邻中枢的活动。
