Although airway smooth muscle contraction is an integral part of the acute and chronic bronchoconstriction observed in conditions such as asthma, the role of this musculature in health is unclear (1).

Gastrointestinal motility occurs by the coordinated contractions of the tunica muscula ris, which forms the outer wall of the alimentary canal from the distal oesophagus to the external anal sphincter ...

A new molecular pathway critical for maintaining the smooth muscle tone that allows the passage of materials through the digestive system is being identified by researchers at UMass Medical School.

Researchers at UT Southwestern Medical Center at Dallas are the first to use genetically engineered mice containing a fluorescent molecule to examine in real time the chemical reactions that result in ...

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— ...

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 ...

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.

Childbirth depends not just on hormones, but on the uterus’s ability to sense physical force. Scientists found that pressure ...
