Light now in sight: Control of a 'blind' neuroreceptor with an optical switch
When nerve cells communicate with one another, specialized receptor molecules on their surfaces play a central role in relaying signals between them. A collaborative venture involving teams of chemists based at Ludwig-Maximilians-Universitat ...

How work tells muscles to grow
We take it for granted, but the fact that our muscles grow when we work them makes them rather unique. Now, researchers have identified a key ingredient needed for that bulking up to take place. A factor produced in working ...

Perfect micro rings woven from muscle fibers: A biological model system that dead-ends in 'absorbing state'
Supplied with sufficient energy, a freight train would ride the rails as far as they go. But nature also knows systems whose dynamics suddenly turn into a kind of endless loop. Like in a hamster wheel, a train ...

Researchers discover that stem cell marker regulates synapse formation
Among stem cell biologists there are few better-known proteins than nestin, whose very presence in an immature cell identifies it as a "stem cell," such as a neural stem cell. As helpful as this is to researchers, ...

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.
