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.

Atomic images of muscle molecules in action have now been captured by researchers, giving possibility of new nanomachines. At the molecular level, muscle contraction is defined by myosin molecules ...

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.
