A light microscope study of fibre diameter and sarcomere length relationships in rigor skeletal muscles

  • P. V. J. Hegarty
  • C. E. Allen


Correlation coefficients between fibre diameter and sarcomere length were significant in relaxed, unfixed muscles in rigor, indicating that fibres with large diameters had short sarcomeres and fibres with small diameters had long sarcomeres. No significant correlations were obtained in muscles from limbs that entered rigor in a folded or stretched position.
