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 ...

Using powerful new visualization technologies, researchers have captured the first 3-D images of the structure of a key muscle receptor, providing new insights on how muscles develop across the animal ...

Adding to the growing fundamental understanding of the machinery of muscle cells, a group of biophysicists describe -- in minute detail -- how actin filaments are stabilized at one of their ends to ...

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 contraction process involves interactions between actin and myosin filaments within the sarcomeres to generate force. News organizations may use or redistribute this image, with proper attribution ...

The structure of a key protein implicated in diseases affecting the heart muscle has been uncovered, scientists say. Researchers, including some from King's College London, say they now understand why ...

Voluntary muscles can be controlled by the person, like muscles in your neck and legs. Involuntary muscles work without you thinking about it, like your heart and stomach muscles. Skeletal muscles ...
