The main types of muscle fibre in the pond loach lateral musculature—red, intermediate and white, distinguished histochemically by myofibrillar ATPase activity—differ in the composition of their native myosin isoforms. However, each of these fibre types expresses a single myosin heavy chain (MHC) ...

Requiring only small amounts of starting muscle tissue (.., 2–10 mg wet weight), muscle fibre type is determined in one-tenth of a 1–3-mm fibre segment, with the remainder of each segment pooled with fibre segments of the same type (I or II) for subsequent protein quantification ...
In the CP muscle, the majority of fibres were type IIC at 2 weeks. At 2 months, more than 20% of the fibres were still type IIC and the proportion of type I fibres as a main component in the adult was smaller than that of the adult. None of the puppies younger than 9 weeks old...
General Structure of a Muscle (Source: SEER Training) Each muscle (mainly skeletal) has an outer covering called the perimysium. It covers and protects the muscle fibres. Around the entire structure lies the fibrous layer of the epimysium which protects the entire muscle. Each bundle of fibre...
The small diameter fibres (referred to also as tonic-like) are distinct in myofibrillar ATPase activity and seem to contain the unique type of MHC, which suggests unique contractile properties for this fibre type.关键词: Misgurnus fossilis L Muscle fibre types Myosin isoforms ...
Here we compare the V of muscle fibres during locomotion with their Vmax. This comparison shows that during slow locomotion, the slow fibres shorten at a velocity that gives peak mechanical power and efficiency and the fast fibres shorten at their optimal velocity when powering maximal movements. ...
A major recent advance in the field of muscle fiber types has been the discovery that myogenic factors regulate fiber phenotypic properties. Myogenic influences occur in limb and trunk (somitic) muscle, but are particularly strong in jaw-closing muscles and extraocular muscles that express some uniqu...
9c,d). Similarly, the decrease in gastrocnemius weight, diameter of muscle fibres and increase in Atrogin-1 and Murf-1 expression levels in denervated muscles were also attenuated in mice injected with miR-29b sponge (Fig. 9c,e,f). Interestingly, in denervation mice injected with miR-29b ...
fibres arrangement within the cells is responsible for these dark and light stripes. visceral muscle visceral muscles are found within organs such as the intestines, the blood vessels and the stomach. these muscle tissues cause contractions within the organs, which help in the transportation of ma...
