MusclesSummary 1. The muscle fibre is regarded as a bundle of myofibrils, embedded in a viscous matrix, the sarcoplasm, the whole being surrounded by a delicate sheath, the sarcolemma. 2. The sarcolemma is a thin, apparently structureless membrane. Preliminary study with the electron microscope ...

247). In living muscles under the interference microscope, the H zone is conspicuous only when the fibre is moderately stretched (neither shortened not greatly stretched), as would be expected on this picture, but the optical conditions are not good enough to measure its width. (4) Constancy ...
The three dimensional structure of these deformities has been visualized in isolated fibres and the orientation of these deformities was determined within the muscle by confocal laser scanning microscopy. We have also shown that the occurrence of morphologically abnormal fibres is greater in muscles with...
Muscles perform a wide range of motile functions in animals. Among various types are skeletal and cardiac muscles, which exhibit a steady auto-oscillation of force and length when they are activated at an intermediate level of contraction. This phenomenon, termed spontaneous oscillatory contraction or...
Muscles can also be described in terms of their contractile velocity, which reflects their relative aerobic or anaerobic metabolism:1 Type I fibres are abundant in myoglobin, mitochondria, and capillaries. They have a slow conduction velocity and as a result are very fatigue resistant. Type IIa fi...

MusclesMicroscopy, ElectronChickensFreezingElectron micrographs of longitudinal ultrathin cryo-sections and plastic sections of chicken pectoralis muscle together with their average images have been used to study in detail the axial structure of the M-band. It was found that M-band structure could vary...
