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 contraction of smooth muscle is an essential process underpinning diverse physiological functions ranging from gastrointestinal motility to vascular regulation. At its core, smooth muscle ...

Using powerful new visualization technologies, researchers have captured the first 3-D images of the structure of a key muscle receptor, providing new insights on how muscles develop across the animal ...

Molecular discoveries may help improve treatments for labor and pain. When labor starts, the uterus must produce steady, ...

Thomas Lapole a reçu pour ses travaux des financements de l’Université Jean Monnet de Saint-Etienne ainsi que du Centre National d'Etudes Spatiales. Cet article est publié dans le cadre de la Fête de ...

Muscle twitches can occur for many reasons, such as a lack of sleep, caffeine use, nutrient deficiencies, overexertion, and stress. Depending on the cause, treatments and remedies may help relieve ...

In a serendipitous discovery, UC San Diego researchers using cryo-EM technology captured the first visualizations of the 3-D structure of the muscle acetylcholine receptor in fetal and adult muscles.
