Abstract
From differences in morphological, histochemical and mechanical properties three types of intrafusal (IF) fibre have been distinguished: “dynamic nuclear bag1”, “static nuclear bag2” and “nuclear chain” fibres. We have recently shown that the muscle spindles in the human masticatory muscles are far more complicated in structure than reported before for human and animal muscle spindles (Eriksson and Thornell, 1985, 1987). To attain further information about the structure and function of human muscle spindles we have analysed the composition of different myofibrillar and cytoskeletal proteins in IF fibres and spindle capsule tissue.
Supported by the Swedish Medical Research Council (3934 and 6874), the K-O. Hansson Foundation, Umeå University, and the Swedish Dental Society.
