Myosin filaments contain tiny globular heads, called cross bridges at regular intervals. Actin-accumulation myopathy is a disorder that primarily affects skeletal muscles, which are muscles that the body uses for movement. People with actin-accumulation myopathy have severe muscle weakness (myopathy) and poor muscle tone (hypotonia) throughout the body. Signs and symptoms of this condition are apparent in infancy and include feeding Actin Myosin: The filaments are composed of actin proteins, troponin and tropomyosin.

P i is then released, allowing myosin to expend the stored energy as a conformational change. The myosin head moves toward the M line, pulling the actin along with it. As the actin is pulled Myofibrils are composed of long proteins including actin, myosin, and.

In addition, actin and myosin have been used for developments towards nanotechnological applications in recent years. Myosin filaments have many heads, which can bind to sites on the actin filament.
