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 ...

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 ...

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 ...

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 ...

There are three types of muscle tissue in the human body including cardiac muscle, smooth muscle, and skeletal muscle. Skeletal muscle fibers are those which are attached to the skeleton. They are ...

Engineers at Washington University in St. Louis have developed a new class of protein-based fibers modeled on the aligned structure of animal skeletal muscle, producing materials that resist ...
