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.

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.

DMD, the most common type of muscular dystrophy, is caused by the absence of dystrophin, a protein that protects muscle from contraction-induced damage. Nearly all boys with DMD require the use of a ...

A concentric contraction is a type of muscle activation that causes tension on your muscle as it shortens. As your muscle shortens, it generates enough force to move an object. This is the most ...

Researchers say a regulatory protein found in skeletal muscle fiber may play an important role in the body's fight or flight response when encountering stressful situations. Researchers at the ...

Researchers at the University of Bristol have created a network of simple mechanical motors that replicates how human muscles respond to increasing load. Built using small electric motors, 3D-printed ...

From your morning stretch to your fastest sprint, every movement depends on the precise dance between actin, myosin, and calcium inside your muscle fibers. Scientists are uncovering not only the ...
