How the bicep tenses is no longer a secret. In every muscle cell there are so-called myofibrils, which contract at the same time. They are responsible for muscle movement. Each of these fibrils ...

Sarcomeres are small repeating subunits of myofibrils, the long cylinders that bundle together to make the muscle fibres. Inside the sarcomeres, filaments of the proteins myosin and actin interact to ...

Myosin was localized in situ in the posthatch chicken pectoralis using isoform-specific mAbs. The distribution among myofibrils was demonstrated by immunofluorescence and by immunogold EM. Fluorescein ...

Researchers have just made the unexpected discovery of a novel organization of muscle fibers in Parophidion vassali, a fish that lives in the Mediterranean Sea and, like many fish, uses specialized ...
