Activities of individual, force-sensitive mechanoreceptors (funnel canal organs) of the terminal segment (dactyl) of the crab leg have been recorded in freely moving animals. During the stance phase of walking receptors discharge in regular bursts that are closely correlated with activity of the opener muscle of the propodite when the leg is used on the trailing side in lateral locomotion. Individual funnel canal organs also show sustained discharges to imposed cuticular strains and strains resulting from resisted muscle contractions. These receptors thus can monitor both internal and external forces that are applied to the leg in locomotion.
已在自由活动的动物中记录了蟹腿末端节段（指节）单个力敏机械感受器（漏斗管器官）的活动。在行走的支撑阶段，当腿在侧向运动中用于后侧时，感受器会有规律地爆发性放电，这与柄节张开肌的活动密切相关。单个漏斗管器官对施加的表皮应变和抵抗性肌肉收缩产生的应变也表现出持续放电。因此，这些感受器可以监测在运动过程中施加到腿部的内部和外部力量。
