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 ...

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 ...
