Proceedings Correlation between ultrastructure and histochemistry of mammalian intrafusal muscle fibres (original) (raw)

This paper examines the correlation between the ultrastructural features and histochemical profiles of mammalian intrafusal muscle fibers, particularly in cat, rabbit, and rat species. By analyzing the differences in ATPase activity and other staining reactions across various parts of the muscle spindle, the study reveals significant variations in histochemical properties, suggesting potential functional implications for muscle fiber specialization. The findings contribute to a deeper understanding of intrafusal muscle fiber types, their structural characteristics, and the physiological roles they play within the muscle spindle.
