Damaged muscles don't just die, they regenerate themselves

A research collaboration between Kumamoto University and Nagasaki University in Japan has found that components leaking from broken muscle fibers activate "satellite" muscle stem cells. While attempting to identify the proteins ...

Skeletal muscle

Skeletal muscle is a form of striated muscle tissue existing under control of the somatic nervous system. It is one of three major muscle types, the others being cardiac and smooth muscle. As its name suggests, skeletal muscle is linked to bone by bundles of collagen fibers known as tendons.

Skeletal muscle is made up of individual components known as muscle fibers. These fibers are long, cylindrical, multinucleated cells composed of actin and myosin myofibrils repeated as a sarcomere, the basic functional unit of the cell and responsible for skeletal muscle's striated appearance and forming the basic machinery necessary for muscle contraction. The term muscle refers to multiple bundles of muscle fibers held together by connective tissue.
