The flow of water within a muscle fiber may dictate how quickly muscle can contract, according to a new study. The flow of water within a muscle fiber may dictate how quickly muscle can contract, ...

Researchers have discovered that a protein called B1N1 is necessary for the heart to contract. The findings shed light not only on what makes a heart beat but also on heart failure, a disease where ...

Without functioning muscles, we wouldn’t be able to do a whole lot. Even our most basic needs, eating and breathing, depend on our muscles. Yet on the molecular level, muscles are quite simple.

Sometimes, people experience random muscle twitches that interrupt their normal daily activities. This is usually not harmful, but can produce discomf.

In a serendipitous discovery, UC San Diego researchers using cryo-EM technology captured the first visualizations of the 3-D structure of the muscle acetylcholine receptor in fetal and adult muscles.

Molecular discoveries may help improve treatments for labor and pain. When labor starts, the uterus must produce steady, precisely timed contractions to allow a safe delivery. Hormones such as ...

Eccentric exercise involves lengthening muscles which increases size by adding stress. Concentric moves shorten muscles for gains with less soreness.

The muscular system works to control the movement of our body and internal organs. Muscle tissue contains something called muscle fibers. Muscle fibers consist of a single muscle cell. They help to ...

Muscle knots are highly irritated muscle fibers that have tightened into a ball in one area of your muscle. These painful, tender spots can feel sore and often occur in your upper back, shoulders, or ...
