E. Huxley and J. Hanson (1954) observed changes in the sarcomeres as muscle tissue shortened. They observed that one zone of the repeated sarcomere arrangement, the "A band," remained relatively ...

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 ...

This growth pattern lengthens the muscle fibers and could decrease the amount of stretch each sarcomere experiences, ...

A single myosin filament connects to two actin filaments on either side, forming a single unit of muscle tissue known as a sarcomere. Intercalated discs connect cardiac muscle cells. Gap junctions ...
