RECENT work on contractile phenomena in muscle 1 indicates that a complete understanding of these processes demands a fuller knowledge of the sub-microscopic morphology and distribution of the mineral ...

Researchers at the Hong Kong University of Science and Technology (HKUST) have created a cutting-edge platform consisting of a dual-laser nonlinear optical microscope to investigate the dynamics of ...

The film explores the muscular system of the human body, detailing the roles and functions of the three types of muscles: skeletal, smooth, and cardiac. Skeletal muscles, which are voluntary and work ...

Muscles make up nearly 40% of the human body and power every move we make, from a child's first steps to recovery after ...

From arthritis and heart failure to diabetes and menopause, many conditions are associated with muscle weakness and increased fat deposits. Now a multidisciplinary team of researchers at the ...

Hierarchical structure of muscle and activation of thin filaments. In both skeletal and cardiac muscles under a relaxed state, a low intracellular calcium ion concentration is maintained and the ...

Numerous motor and structural proteins compose a highly ordered structure known as the sarcomere, the basic unit of muscle contraction in heart and skeletal muscles. Sarcomeric myosin heavy chain ...

The muscular system works to control the movement of our body and internal organs. Muscle tissue contains something called muscle fibers. Muscle fibers consist of a single muscle cell. They help to ...
