Orthogonal Diameters in the Analysis of Muscle Fibre Size and Form
Nature, 1963DISTRIBUTIONAL changes in sizes of fibres have been correlated with pathological processes affecting muscle. Micrometry of muscle fibres in histological cross-section, for example, has been frequently used to follow the course of denervation atrophy1.

Estimation of Changes in Single Muscle Fibre Diameter in Different Solutions by Diffraction Studies
Pflugers Archiv European Journal of Physiology, 1981Studies of the effects of varying tonicity on the contraction of muscle fibres requires a knowledge of the corresponding changes in fibre diameters, if the observed mechanical changes are to be attributed to various factors, including that of the interfilamental spacing.

The tensile properties of single muscle fibres isolated from porcine longissimus and iliocostalis muscles conditioned for various lengths of time and cooked at different temperatures for 1 h were investigated. The stress-strain curves of fibres extended to fracture were r-shaped with yield points of 2-5% resting length in raw fibres and 10-20% in ...

The diameter and mean sarcomere length of individual muscle fibres
Life Sciences, 1975Abstract Studies of the coefficients of variation and the repeatibility of the measurements indicate that a sample of 25 fibres is sufficient to provide an accurate estimate of the mean fibre diameter and sarcomere length of a muscle. There is a significant negative correlation (−0.55) between the diameter and mean sarcomere length of an individual ...

Fibre distribution and fibre diameters in two muscles of swedish moose (Alces alces L.)
Comparative Biochemistry and Physiology Part A: Physiology, 19821. Muscle samples from M. semitendinosus (S) and M. longissimus (L) were taken by autopsy, shortly after killing from 36 moose ranging approximately from 5 months to 6 yr of age. 2. The moose muscle contains three populations of fibres namely beta R, alpha R and alpha W.

Abstract 1. 1. Fibre diameter and sarcomere length were measured in pre- and post-rigor biceps brachii muscle of adult mice (rigor muscle in folded, stretched or resting position). 2. 2. Fibre unit volume (FUV) (fibre diameter) 2 × sarcomere length of pre-rigor muscle was almost constant between animals despite variation in fibre diameter ...

Fibre type grouping and end-plate diameter in human skeletal muscle
Journal of the Neurological Sciences, 1971Abstract The maximum diameters of end-plates in muscles with abnormally high functional terminal innervation ratios were measured and expressed as histograms. Subsequent histochemical examination showed that histograms with a normal type of distribution were associated with muscles not showing fibre type grouping, whereas muscles with fibre type ...

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 ...

Increase in Diameter of Muscle Fibres in the Foetal Pig
British Veterinary Journal, 1972SUMMARY Skeletal muscle fibres from foetal pigs between 45 days’ gestation and 7 days after birth were examined and their growth in diameter measured by light microscopy of paraffin sections. Three developmental stages are described: A. Development of large myotubes. Up to day 55. B.
