Researchers at Osaka University used electron cryomicroscopy (CryoEM) to image essential cardiac muscle components, known as thin filaments, with unprecedented resolution. They also discovered the ...

Contraction of the heart is driven by cyclical interactions between myosin and actin filaments powered by ATP hydrolysis. The modular structure of heart muscle and the organ-level synchrony of the ...

Atrial fibrillation, heart failure and stroke—hypertrophic cardiomyopathy can lead to many serious health conditions and is a major cause of sudden cardiac death in people younger than 35. "The heart ...

At the molecular level, muscle contraction is defined by myosin molecules pulling actin filaments. New electron cryomicroscopy images with unprecedented resolution taken by researchers at Osaka ...

Skeletal muscle cells (myofibres) are large and multinucleated, containing highly organized contractile proteins that interact with each other to generate force and allow movement of the body. Each ...

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.
