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.

The contractile responses of esophageal smooth muscle (SM) induced by platelet-activating factor (PAF) involve the activation of L-type voltage-dependent calcium channels (L-type VDCCs), ...

Calcium is the essential "on switch" for muscle contractions and a critical partner in maintaining hydration during hard ...

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 ...

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, ...

A research group led by Dr. Keisuke Obara, Dr. Kento Yoshioka, and Professor Yoshio Tanaka from the Department of Chemical Pharmacology, Faculty of Pharmaceutical Sciences, Toho University, has ...

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 ...

Calcium is vital for bones, muscles, nerves, and heart health, and can be obtained from various non-dairy drinks.
