Muscle Density, but Not Size, Correlates Well With Muscle Strength and Physical Performance
Journal of the American Medical Directors Association, 2021There is increasing evidence that muscle volume and mass are poor predictors of muscle strength and physical performance. Other assessments of muscle quality such as skeletal muscle density measured by computed tomography (CT) may be more important. The aim of this study was to explore associations of muscle size and density with handgrip strength (HGS)

Human jaw muscle strength and size in relation to limb muscle strength and size
European Journal of Oral Sciences, 2004The aim of the present study was to investigate to what extent general factors (e.g. genotype, hormones) and factors at the craniofacial level (e.g. craniofacial size, jaw muscle architecture) contribute to the size and strength of the jaw muscles. A strong relationship of jaw muscle size and strength with that of other muscles would argue for general ...

Size of the Superior Palpebral Involuntary Muscle (Müller Muscle)
Journal of Craniofacial Surgery, 2010The aim of this study was to elucidate the width and length of the superior palpebral muscle by using anti-α-smooth muscle actin antibody. Ten orbits of 5 adult Korean cadavers were used. Eyelids were cut in vertical planes through midpupilliary, medial limbus, and lateral limbus and in horizontal planes at the anterior border of the superior ...

Control of the Size of the Human Muscle Mass
Annual Review of Physiology, 2004▪ Abstract This review is divided into two parts, the first dealing with the cell and molecular biology of muscle in terms of growth and wasting and the second being an account of current knowledge of physiological mechanisms involved in the alteration of size of the human muscle mass.

Muscle Dynamics, Size Principle, and Stability
IEEE Transactions on Biomedical Engineering, 1984A mathematical model of skeletal muscle activation during small or isometric movements is discussed with the following attributes. A direct relationship between the stimulus rate and the active state is established. A piecewise linear relation between the length of the contractile element and the isometric force is considered.

Abdominal muscle size and symmetry in normal subjects
Muscle and Nerve, 2006AbstractThis study was undertaken to establish normal reference ranges for abdominal muscle size and symmetry and to examine the effects on these of gender and age. We studied 123 subjects, consisting of 55 men (aged 21–72 years) and 68 women (aged 20–64 years). Real‐time ultrasound imaging of the abdominal muscles was performed.

The sizes of the nerve fibres of muscle nerves
Proceedings of the Royal Society of London. Series B - Biological Sciences, 1951Abstract The diameters of the fibres in the nerves innervating twenty-five muscles in the rabbit have been measured and two types of muscle nerves are distinguished. (1) The 'bimodal’ nerves of nearly all limb muscles and the extrinsic eye muscles show two peaks in the size-frequency distribution and contain many large fibres (up to ...

Size Principle of Striated Muscle Cells
Netherlands Journal of Zoology, 1997We have investigated the relationship between cross-sectional area (CSA) and maximum rate of oxygen consumption (VO2max, in nmol .mm-3 .s-1) of heart and skeletal muscle cells from different species. VO2max and CSA were determined for single muscle fibres of Xenopus laevis at 20°C and for cardiomyocytes in thin trabeculae dissected from the right ...
