A new kind of muscle receptor has been described in the medicinal leech, the first stretch receptor in a soft-bodied invertebrate to be identified and characterized. 2. The sensory responses to stretch in these receptors are different from those of other more well known muscle receptors such as vertebrate spindles or crustacean stretch receptors. 3. The leech receptors provide the sensory innervation for the tubular muscle layers of the body wall, and they respond to stretch of the muscle with hyperpolarizing potentials that are conducted passively to the CNS. 4. This review summarizes their unusual morphology, membrane properties and sensory responses to stretch; their association with particular muscle fibre types in leech body wall; their synaptic connections; and their role in a well characterized rhythmic behaviour in the leech-swimming.

一种新型的肌肉受体已在药用水蛭中被描述，它是软体无脊椎动物中首个被识别和鉴定的牵张受体。2. 这些受体对牵张的感觉反应不同于其他更为知名的肌肉受体，如脊椎动物的肌梭或甲壳类动物的牵张受体。3. 水蛭受体为体壁的管状肌肉层提供感觉神经支配，它们对肌肉牵张的反应是产生超极化电位，并被动传导至中枢神经系统。4. 本综述总结了它们不同寻常的形态学、膜特性以及对牵张的感觉反应；它们与水蛭体壁中特定肌肉纤维类型的关联；它们的突触连接；以及它们在水蛭游泳这一特征明确的节律性行为中的作用。
