A new swtudy sheds light onto the causes and potential solutions to the GI problems associated with myotonic dystrophy type 1 (DM1), the most common form of adult-onset muscular dystrophy, affecting ...

An international team has produced the first high-resolution 3D image of the sarcomere, the basic contractile unit of skeletal and heart muscle cells, by using electron cryo-tomography. Electron ...

The flow of water within a muscle fiber may dictate how quickly muscle can contract, according to a new study. The flow of water within a muscle fiber may dictate how quickly muscle can contract, ...

MHH scientist investigates how pro-inflammatory cytokines interfere with muscle metabolism and actively transform muscles.

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.
