Muscle is a soft tissue composed of elongated cells (muscle fibres) that produce force and motion through contraction. Involuntary cardiac and smooth muscles are responsible for contraction of the heart and movement of substances through hollow organ systems, respectively, and voluntary skeletal muscles...
Skeletal muscleis the main tissue responsible for body posture and movement. To accomplish this function, skeletal muscle requires a major part of whole-body energy metabolism. Even at rest the musculature is responsible for approximately 30% of the metabolic rate of human body. With this metabolic...
theskeletonandconstitutesthe bulk of the body’s muscle tissue. The multinucleated fibres are under the control of the somaticnervous systemand elicit movement by forces exerted on the skeleton similar to levers and pulleys. The rhythmic contraction ofcardiac muscleis regulated by the sinoatrial node...
2. A contractile organ consisting of a special bundle of muscle tissue, which moves a particular bone, part, or substance of the body: the heart muscle; the muscles of the arm. 3. Muscular strength: enough muscle to be a high jumper. 4. Informal Power or authority: put some muscle int...

Following starvation for 130 days the body weight of cod decreased by 30%, the diameter of the red muscle fibres by 15 %(P < 0.001) and that of the white m... MG Walker - 《J.cons.int.explor.mer》 被引量: 86发表: 1971年 The effect of starvation in the rat on metabolite concent...
The multinucleated fibres are under the control of the somatic nervous system and elicit movement by forces exerted on the skeleton similar to levers and pulleys. The rhythmic contraction of cardiac muscle is regulated by the sinoatrial node, the heart’s pacemaker. Although cardiac muscle is ...
This preferential recruitment of the faster fibres for the faster tasks indicates that in some circumstances motor unit recruitment during locomotion can match the contractile properties of the muscle fibres to the mechanical demands of the contraction. 展开 关键词: muscle, recruitment, fibre-type ...
Adrenalectomy of obese mice increases the weights of their skeletal muscles towards normal. We have investigated whether this increased growth was specific for the fast phasic muscles and white, glycolytic fibres most affected by obesity and whether the proportions of the different fibre types were re...
