In light of the aforementioned MyoD data, we first performed RNA-seq analysis of muscle cells that were isolated from hind-limb skeletal muscles of wild-type (WT) and MyoD-null (MKO) mice and cultured in growth medium (GM, Pax7+, and MyoD+) or differentiation medium (DM, MyoG+) (Suppl...
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 ...
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...
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...
Skeletal muscles are the muscles that are under the control of the somatic nervous system (voluntary) and are striated. Also they have many nuclei and are triggered into motion via electrical impulses from the motor neuron terminals connected to the muscle fibres. These motor neurons are ...
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...
