The standard textbook model of muscle contraction includes only two main players, the filaments actin and myosin, which slide past each other, causing the sarcomere—the basic unit of muscle tissue—to ...

Muscle contraction is the tightening, shortening, or lengthening of muscles when you do some activity. It can happen when you hold or pick up something, or when you stretch or exercise with weights.

Genetic inhibition of RyR1-mediated calcium-induced calcium release reveals its minimal role in skeletal muscle contraction and its critical contribution to malignant hyperthermia risk You are free to ...

Dystrophin is part of a protein complex linking the cytoskeleton of muscle fibers to the surrounding connective tissue (basal lamina). It’s a long protein with numerous redundant coils (purple balls), ...

New research has shown one type of muscle contraction is most effective at increasing muscle strength and muscle size -- and rather than lifting weights, the emphasis should be on lowering them. Good ...

The flow of water within a muscle fiber may dictate how quickly muscle can contract, according to a new study. The flow of water within a muscle fiber may dictate how quickly muscle can contract, ...
