Inspired by the structure of muscles, an innovative new strategy for creating fiber actuators could lead to advances in robotics, prosthetics, and smart clothing, according to a Penn State led team of ...

A new study comparing muscle structure between active and inactive people has found that older people who regularly do endurance exercise maintain similar muscle characteristics to younger ...

- Muscle cells, also known as myocytes, are specialized cells designed for contraction and force production. Skeletal Muscle Cells: These cells are long, cylindrical, and have a striated (or striped) ...

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 ...

Hierarchical structure of muscle and activation of thin filaments. In both skeletal and cardiac muscles under a relaxed state, a low intracellular calcium ion concentration is maintained and the ...

Muscle loss, or atrophy, due to inactivity is common after illness, injury, hospitalization or falls, and becomes increasingly frequent with aging.

For most of his career, Richard Lieber ’78, Ph.D. ’83, has focused on understanding and solving painful and debilitating muscle contractures that are the result of cerebral palsy, stroke and spinal ...

While humans lose muscle within weeks of inactivity, brown bears preserve muscle during hibernation, offering clues for maintaining our muscle health.
