Superficial lumbrical spindles of the cat show several important differences as compared with the classic picture of the spindle, derived principally from tenuissimus. Thus long chain fibres occur in a high proportion of superficial lumbrical spindles, and there is great individual variation in the number of bag fibres present. This study is especially concerned with the morphology and relationships of the bag1, fibre, which are again highly unusual. Most notably, bag1 fibres were almost always the longest intrafusal fibres, typically exceeding bag2 fibres by about 2 mm in total length. They also commonly exhibited the greatest diameter, especially in the extracapsular region where, uniquely, they normally increased in size on leaving the capsule, often becoming similar to extrafusal fibres in this respect. In a few spindles where there was only a single bag fibre this was more often a bag1 than is the case for similar spindles in tenuissimus, and in tandem-linked spindles the continuous bag fibres were more often bag1 than bag2. These results contribute to growing evidence that different muscles exhibit characteristic features of the structure and innervation of their proprioceptors, which may reflect adaptations to local control requirements.
