Topography and ultrastructural organization of proprioceptors in the striated parietal muscle of the hagfish, Myxine glutinosa, are described. Due to the topographical location of the afferent nerve terminals four subtypes of proprioceptors are distinguished. Type 1-receptor and type 2-receptor are localized in an encapsulated and lamellated corpuscular organ located along and above the myosepta of the parietal muscle. Type 3-receptor is composed of a complex of free en plaque nerve endings within the dense collagen fibre texture at the site where myoseptum, muscle fascia and body fascia fuse to a raphe. Type 4-receptor resembles type 3 but it is localized in the straight collagen fibre bundles of the myoseptum and the body fascia. A proprioceptive function of the nerve terminals is discussed.
本文描述了盲鳗（Myxine glutinosa）横纹顶叶肌中本体感受器的拓扑结构和超微结构组织。根据传入神经末梢的拓扑位置，区分出四种本体感受器亚型。1型感受器和2型感受器位于沿顶叶肌肌隔并在其上方的一个被囊化且分层的小球状器官中。3型感受器由在肌隔、肌肉筋膜和体筋膜融合形成缝的部位的致密胶原纤维结构内的游离板状神经末梢复合体组成。4型感受器与3型相似，但它位于肌隔和体筋膜的直胶原纤维束中。本文还讨论了神经末梢的本体感受功能。
