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.
A new study by researchers at Yale and Johns Hopkins University has discovered how asthmatic bronchial spasms — muscle contractions in the airway that cause difficulty breathing in asthma patients— ...
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), ...

Compound found in rice bran can suppress intestinal contractions by inhibiting calcium influx
A research team at Toho University has revealed that ferulic acid (FA), a polyphenol abundant in rice bran, suppresses intestinal smooth muscle contractions by inhibiting voltage-dependent calcium ...
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 ...
