However, skeletal muscle is primarily made of muscle fibers, which are bundles of lots of proteins called myofibrils. Each myofibril contains smaller protein structures called sarcomeres.

New research reveals how exercise transforms muscles into communication hubs that release beneficial molecules throughout the ...

Dr. Gabrielle Lyon is on a mission to bring attention to the importance of strength. The "health of skeletal muscle" is the "focal point" of health and wellness, Dr. Lyon said during an exclusive ...

Rhabdomyolysis is when skeletal muscle tissue deteriorates. This can produce substances that increase the risk of kidney damage. Learn more here.

Skeletal muscles connect to the bones by tendons and are responsible for movement. Bundles of muscle fibers, known as myocytes, make up the skeletal muscles. Each myocyte contains myofibrils that ...

Muscle mass is a part of your lean body mass. It’s difficult to calculate lean body mass, let alone muscle mass, but there are some ways to get an idea of how much you have. Learn more.

Measuring roughly 0.2 inch (5 millimeters) in length, it is the smallest skeletal muscle in the human body. Here, you can see the stapedius muscle connected to a small bone called the stapes.

When you pull a muscle, you tear it, but the damage can vary in severity. Certain muscles are more at risk, and recovery is fairly straightforward.
