Carbachol-evoked contractions of descending colon strips from patients with CC (A, B). Dose-response effects of carbachol on the amplitude of contraction of circular (Aa) and longitudinal (Ba) muscle ...

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.

Researchers have developed a new imaging tool, called electromyometrial imaging (EMMI), to create real-time, three-dimensional images and maps of contractions during labor. The non-invasive imaging ...
