The mechanism of skeletal muscle contraction is a process that relies on calcium signaling. However, the physiological role of calcium-induced calcium release (CICR) through the ryanodine receptor ...

IT is well established that an increase in the intracellular concentration of ionized calcium after excitation in the membrane is the key factor for initiation of contraction of various types of ...

The ability to modify the intracellular concentrations of divalent calcium ions is vital to normal cell functioning. In the cells of the cardiac muscle, calcium ions play a crucial role in coupling ...

IT is believed that muscle contracts or relaxes depending on the concentration of calcium in the sarcoplasm: when the concentration rises to some required level the muscle contracts; when it falls ...

Ferulic acid suppresses ileal smooth muscle contraction by inhibiting calcium ion influx through voltage-dependent calcium channels. This action may help prevent or treat excessive intestinal motility ...

Scientists discover that muscles repair themselves by moving thousands of internal nuclei, a rapid process that is key after ...

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.

Biomedical engineers have grown muscles in a lab to better understand and test treatments for a group of extremely rare muscle disorders called dysferlinopathy or limb girdle muscular dystrophies 2B ...
