Skeletal muscles are by far the largest organ of the human body, accounting for up to 40%–50% of the body weight. In the past much of our knowledge on muscle contraction and relaxation was obtained from experiments with isolated frog muscle or single muscle fibers stimulated with electric pu...

Each section has its own introduction and covers all key components. That means from the muscle and its contraction to the control of metabolic fuels, and from renal filtration to the control of breathing, you have everything you need on physiology in one place. But don't just take our wor...
在人类中,不能直接测量PICs,但可以通过量化共享共同突触输入的成对MU的起始-偏移滞后来估计PICs的大小,也称为成对运动单元分析(即ΔF)技术。 Ageing is associated with several alterations within the neuromuscular system that underlie the...
Calcium (Ca2+) release from intracellular stores plays a key role in the regulation of skeletal muscle contraction. The type 1 ryanodine receptors (RyR1) is the major Ca2+ release channel on the sarcoplasmic reticulum (SR) of myocytes in skeletal muscle and is required for excitation–contraction...
The mind-muscle connection refers to the conscious effort to focus one’s attention on the contraction of a specific muscle or muscle group during exercise. This practice involves mentally engaging with the working muscle, aiming to isolate and enhance its activation without relying solely on the ...
(dnaJ); protein ubiquitination (zfp364); proteolysis (ctse, ctsh, ctsl, Aplp2, serpina3n, and tmprss2); regulation of cell shape (sprr2A); regulation of muscle contraction (my19 and cnn1); response to oxidative stress (prdx1 and prnp); synaptic transmission (syn1); and tRNA amino...
23Citations 1Altmetric Metrics Abstract The regulation of muscle contraction is a critical function in the cardiovascular system, and abnormalities may be life-threatening or cause illness. The common basic mechanism in muscle contraction is the interaction between the protein filaments myosin and actin...
