Using powerful new visualization technologies, researchers have captured the first 3-D images of the structure of a key muscle receptor, providing new insights on how muscles develop across the animal ...

From arthritis and heart failure to diabetes and menopause, many conditions are associated with muscle weakness and increased fat deposits. Now a multidisciplinary team of researchers at the ...

Adding to the growing fundamental understanding of the machinery of muscle cells, a group of biophysicists describe -- in minute detail -- how actin filaments are stabilized at one of their ends to ...

Numerous motor and structural proteins compose a highly ordered structure known as the sarcomere, the basic unit of muscle contraction in heart and skeletal muscles. Sarcomeric myosin heavy chain ...

The contraction process involves interactions between actin and myosin filaments within the sarcomeres to generate force. News organizations may use or redistribute this image, with proper attribution ...

A new study has observed differences in the shape, structure and mechanical properties of nuclei in trained and untrained individuals, potentially helping to explain the anti-aging effects of exercise ...

There are three types of muscle tissue in the human body including cardiac muscle, smooth muscle, and skeletal muscle. Skeletal muscle fibers are those which are attached to the skeleton. They are ...

Maternal antenatal creatine supplementation protects the brain, kidney, and diaphragm against the effects of birth asphyxia in the spiny mouse. In this study, we examined creatine’s potential to ...

Voluntary muscles can be controlled by the person, like muscles in your neck and legs. Involuntary muscles work without you thinking about it, like your heart and stomach muscles. Skeletal muscles ...

Muscle loss isn't just a sign of aging—it’s a metabolic crisis you can prevent. Learn how strategic movement and targeted nutrition can safeguard your mobility and longevity.
